In the earlier article, we discussed how Rusticide helps in the removal of rust from steel.

Now once the corrosion (rust) has been treated using Rusticide, it is necessary to prevent it from rusting thereafter to ensure that the structure can meet its designed service life.Sunanda Global has exactly developed a tailormade ready-to-use product - POLYALK FIXOPRIME.

The high alkalinity of cement fortified by high alkalinity, high flexural strength, and extra adhesion owing to specially engineered polymers in POLYALK FIXOPRIME, give long-lasting protection against corrosion (rusting) of steel rebars.

Being cementitious, Polyalk Fixoprime coated rebars do not suffer the loss of a bond when embedded in concrete, whereas epoxy-coated bars are prone to suffer substantial loss of bond.STEPS TO USE POLYALK FIXOPRIME Clean the steel surface with a stiff wire brush to remove loosely held rust particles/ scales.

Apply RUSTICIDE with cotton waste swab as per specification.

Mix 1 Kg of POLYALK FIXOPRIME with 1.25 Kgs of fresh grey cement, using a mechanical stirrer, to form a lump free slurry Apply this slurry to the steel rebar surface with a brush taking care to avoid pinholes.Allow this coat to set for a minimum of six hours (or preferably till the next day) Apply a second coat of the slurry carefully and allow this coat to set.

The Jumeirah Lakes Towers (JLT) is a huge development in Dubai.

Ecological difficulties in the United Arab Emirates (UAE) are brought about by the misuse of common assets, quick population development, and high energy interest.

Problem:   Since the structures are located on the seafront.

The rate of corrosion is very high.In Dubai, RCC structures like the star tower in Jumeirah lake, Dubai are exposed to corrosive environments.

Conclusion:  To protect huge development from a corrosive environment, we have suggested installing galvanic Sacrificial Anode which will help for Cathodic Protection.

Galvanic Anode systems are self-regulating, with no maintenance required, no continuous adjustment.

It is a well-known fact that corrosion of steel reduces the service life of structures.

Once steel rebars start corroding (rusting), the reinforced concrete structure begins deteriorating.

Well, Guess What?Sunanda Global has developed and created a miracle product called RUSTICIDE, a single component sulphate and chloride-free liquid, which in one operation removes rust and prevents further rusting of steel.

Embedded steel in repairable structures.

Apply sufficient RUSTICIDE on the affected metal surface using a cotton waste swab.Leave it in contact with the surface until the red color of the corroded steel surface gets converted to the nearest original black.An excess application may sometimes give a whitish black surface.Remove the freed loose rust particles by brush after a minimum duration of 24 hours.

The reddish rusted surface is still left exposed sometimes after the detachment of loose scales.

Generally, it is very tedious and time consuming to apply cement plaster on smooth concrete surfaces, generally on account of poor interfacial bonding.Before cement plastering is done, concrete slabs (soffits or ceilings), walls, columns, beams are hacked with a chisel and hammer in order to roughen their surfaces to enable the plaster to adhere to the concrete surface.

However, there is no way to maintain uniformity and consistency in the number of hacks per sq.

Adding more water to this debonded plaster compromises the original water-cement ratio, significantly reduces the strength, life and quality of plaster.

Hence, it is recommended to do plastering right the first time.This makes us wonder how can we prevent plaster from debonding, increase the speed of plastering, and in turn increase the speed of the construction?Well, no need to worry!SUNANDA GLOBAL, one of the top manufacturers of construction chemicals in India has managed the impossible.

The company has developed ‘HACK AID PLAST’ - a path-breaking product to replace the conventional methodology of hacking.HACK AID PLAST  is a unique single component liquid bonding agent for plaster that strengthens the bond between the plaster and concrete.HACK AID PLAST is an efficient and cost-effective product that costs approximately Rs.

This product is a customized solution that completely eliminates the need to hack concrete surfaces that will receive plaster.Benefits of using Hack Aid PlastIt ensures complete contact and bonding of plaster with concrete surfaces.Significantly reduces wastage and rebound loss of plaster.Speed of the work in plastering is significantly increased which results in significant savings in labour costs.

The exclusion of wet from buildings is thus not solely fascinating however conjointly AN utmost concern to the residents of the buildings.Water seepage through external wallsIn Mumbai, because of a significant downfall, water flowing through external walls is found to be a standard defect faced by the householders.In general, watercourse through external walls at intervals the primary 5 years of building completion.

the matter is additionally combined by Mumbai's high wetness and copious downfall.

Building envelopes should, therefore, be adequately designed and made to stop the ingress of water.General reasons for water seepage through external walls:1.Joints and cracks in the walls2.Absorption and permeation of the materials3.Construction joints in the walls4.Penetrating dampness5.Rising dampness due to capillary action6.Poor construction practices7.Honeycomb structures in concrete or plaster.8.Separation gapsWaterproofing Systems & MaterialsWater tightness of external walls is typically achieved by providing adequate wall thickness, correct coming up with at construction joints, and surface rendering and finishes that function as a barrier against water ingress.

Generally, no consideration is paid towards significant regions like partition holes, honeycomb zones, sodden verification courses at the platform level, etc.

This results in serious leakages through external walls and damages to high-priced internal paints & finishing.Significance of external wall coatingUse of SUNANDA Polyalk WP and SUNANDA Polyfill AR.SUNANDA, Polyalk WP waterproofing coating can be applied on all types of exterior concrete surfaces.Features and Benefits of POLYALK WP :Confirms to I.S.

Indian Construction Chemical Company 'Sunanda Speciality Coatings Pvt.

Ltd.' bagged the award for the 'Development of Anti-washout admixture' for the primary time within the Indian continent.

Hon'ble Chief Minister of Gujarat Mrs. Anandiben Patel, Chief Guest at the inauguration of India Chem perform congratulated the winners, as an encouragement to indigenous R and innovation in the chemicals sector, that is assumed to be one of the key stakeholders in creating Hon'ble Prime Minister'sMake in India' program successful.Sunanda Company's Chairman and manager, Dr. Surendra Manjrekar distinguished that concrete once poured underwater can disintegrate because the cement gets washed away leading to concrete not setting.

generally over the ninetieth of the cement is washed away leading to a colossal loss in terms of cash, resources, and poor quality of underwater construction.This novel anti-washout admixture for concrete by Sunanda to be used for the underwater construction of a weir for the Srisailam Dam (India's ordinal largest hydropower project) across the avatar watercourse in the province, India Same.

Since there aren't any makers of anti-washout admixture in India, this development was important involving over one hundred trials.

This admixture permits construction to require place underwater with but V-E Day loss of cement and has the potential to revolutionize the development of underwater structures like dams, bridge piers jetties, weirs, canals, foundations, etc.

In the earlier article, we discussed how Rusticide helps in removal of rust from steel.

Now once the corrosion (rust) has been treated using Rusticide, it is necessary to prevent it from rusting thereafter to ensure that the structure can meet its designed service life.Sunanda Global has exactly developed a tailormade ready-to-use product - POLYALK FIXOPRIME.

The high alkalinity of cement fortified by high alkalinity, high flexural strength, and extra adhesion owing to specially engineered polymers in POLYALK FIXOPRIME, give long-lasting protection against corrosion (rusting) of steel rebars.

Being cementitious, Polyalk Fixoprime coated rebars do not suffer the loss of a bond when embedded in concrete, whereas epoxy-coated bars are prone to suffer substantial loss of bond.STEPS TO USE POLYALK FIXOPRIME Clean the steel surface with a stiff wire brush to remove loosely held rust particles/ scales.

Apply RUSTICIDE with cotton waste swab as per specification.

Mix 1 Kg of POLYALK FIXOPRIME with 1.25 Kgs of fresh grey cement, using a mechanical stirrer, to form a lump free slurry Apply this slurry to the steel rebar surface with a brush taking care to avoid pinholes.Allow this coat to set for a minimum of six hours (or preferably till the next day) Apply a second coat of the slurry carefully and allow this coat to set.

Generally, it is very tedious and time consuming to apply cement plaster on smooth concrete surfaces, generally on account of poor interfacial bonding.Before cement plastering is done, concrete slabs (soffits or ceilings), walls, columns, beams are hacked with a chisel and hammer in order to roughen their surfaces to enable the plaster to adhere to the concrete surface.

However, there is no way to maintain uniformity and consistency in the number of hacks per sq.

Adding more water to this debonded plaster compromises the original water-cement ratio, significantly reduces the strength, life and quality of plaster.

Hence, it is recommended to do plastering right the first time.This makes us wonder how can we prevent plaster from debonding, increase the speed of plastering, and in turn increase the speed of the construction?Well, no need to worry!SUNANDA GLOBAL, one of the top manufacturers of construction chemicals in India has managed the impossible.

The company has developed ‘HACK AID PLAST’ - a path-breaking product to replace the conventional methodology of hacking.HACK AID PLAST  is a unique single component liquid bonding agent for plaster that strengthens the bond between the plaster and concrete.HACK AID PLAST is an efficient and cost-effective product that costs approximately Rs.

This product is a customized solution that completely eliminates the need to hack concrete surfaces that will receive plaster.Benefits of using Hack Aid PlastIt ensures complete contact and bonding of plaster with concrete surfaces.Significantly reduces wastage and rebound loss of plaster.Speed of the work in plastering is significantly increased which results in significant savings in labour costs.

Indian Construction Chemical Company 'Sunanda Speciality Coatings Pvt.

Ltd.' bagged the award for the 'Development of Anti-washout admixture' for the primary time within the Indian continent.

Hon'ble Chief Minister of Gujarat Mrs. Anandiben Patel, Chief Guest at the inauguration of India Chem perform congratulated the winners, as an encouragement to indigenous R and innovation in the chemicals sector, that is assumed to be one of the key stakeholders in creating Hon'ble Prime Minister'sMake in India' program successful.Sunanda Company's Chairman and manager, Dr. Surendra Manjrekar distinguished that concrete once poured underwater can disintegrate because the cement gets washed away leading to concrete not setting.

generally over the ninetieth of the cement is washed away leading to a colossal loss in terms of cash, resources, and poor quality of underwater construction.This novel anti-washout admixture for concrete by Sunanda to be used for the underwater construction of a weir for the Srisailam Dam (India's ordinal largest hydropower project) across the avatar watercourse in the province, India Same.

Since there aren't any makers of anti-washout admixture in India, this development was important involving over one hundred trials.

This admixture permits construction to require place underwater with but V-E Day loss of cement and has the potential to revolutionize the development of underwater structures like dams, bridge piers jetties, weirs, canals, foundations, etc.

  Water discharge or additional unconditionally wet ingress in buildings results in damp, uncomfortable internal environments; deterioration of internal finishes (including mold growth); unpleasant damp areas on wall and ceiling surfaces and multiplied concentrations of harmful pollutants moving occupant's health.

The exclusion of wet from buildings is thus not solely fascinating however conjointly AN utmost concern to the residents of the buildings.Water seepage through external wallsIn Mumbai, because of a significant downfall, water flowing through external walls is found to be a standard defect faced by the householders.In general, watercourse through external walls at intervals the primary 5 years of building completion.

the matter is additionally combined by Mumbai's high wetness and copious downfall.

Building envelopes should, therefore, be adequately designed and made to stop the ingress of water.General reasons for water seepage through external walls:1.Joints and cracks in the walls2.Absorption and permeation of the materials3.Construction joints in the walls4.Penetrating dampness5.Rising dampness due to capillary action6.Poor construction practices7.Honeycomb structures in concrete or plaster.8.Separation gapsWaterproofing Systems & MaterialsWater tightness of external walls is typically achieved by providing adequate wall thickness, correct coming up with at construction joints, and surface rendering and finishes that function as a barrier against water ingress.

Generally, no consideration is paid towards significant regions like partition holes, honeycomb zones, sodden verification courses at the platform level, etc.

This results in serious leakages through external walls and damages to high-priced internal paints & finishing.Significance of external wall coatingUse of SUNANDA Polyalk WP and SUNANDA Polyfill AR.SUNANDA, Polyalk WP waterproofing coating can be applied on all types of exterior concrete surfaces.Features and Benefits of POLYALK WP :Confirms to I.S.
