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. It’s the complete solution to treating corrosion of steel bars.
ADVANTAGES
RUSTICIDE is a rust remover liquid for steel that treats corroded rebars in one operation.
APPLICATIONS
Rusticide is a rust remover and passivator and prevents further corrosion of
- New/ old reinforcement steel.
- Embedded steel in repairable structures.
- Steel structures such as tanks, water pipelines, effluent pipelines, trusses, purlins, rafters, and other structural members.
Simple Methodology To Use Rusticide:
- Initially remove loose rust by mechanical means like wire brushing, chipping, hammering, etc. depending on the extent of corrosion.
- 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. This should be re-treated with RUSTICIDE.
- A passivating coating like POLYALK FIXOPRIME may be applied after the surface totally dries up (around 48 hours later) as per specification.

In the next series, we will discuss the prevention and passivation of corrosion of steel rebars.
Mechanism of Waterproofing by Proper Cement HydrationOne of the products of hydration of cement is cementgel or Tobermorite, which is formed upto water cement ratio 0.65 to 0.7.
At lower w/c ratio, it is formed more and more and vice versa.
However, actually in practice at average job, we end up getting the permeability anywhere between 10-6 to 10-8 cm/sec.
This is mainly due to uncontrolled w/c ratio, lack of curing and also other bad detailing.Combination of Conventional and Non-Conventional WaysVarious ways of waterproofing the structures are recommended.
However, a discerning client and the consultant need to study all the possible parameters, positive as well as negative, and then come to a recommendatory conclusion.
Conventional ways of waterproofing are like brickbat Coba followed by IPS.
The importance of sustainable building practices has led to significant innovation in the products that can help in making concrete more durable and improve its overall resistance.
The addition of an integral waterproofing compound intends to make the concrete waterproof and thereby increase the overall strength and lifespan of the concrete.Integral waterproofing compounds have been utilized since the last twenty years, owing to their durability, high strength, corrosion resistance, and high retention properties, among others.The trends of the integral waterproofing compound industry vary with different geographical regions.
The report also provides a country-based analysis for all the leading countries in every region, including the U.S., Canada, Mexico, Germany, the U.K., Italy, China, India, Japan, Australia, Brazil, Argentina, and Saudi Arabia, among others.
Concrete is one of the most utilized materials in the construction industry, owing to its versatility, low cost, high strength, abundance and easy availability.
The major advantage of encompassing concrete is that it is very flexible and can be put into any shape or sizes.
The deterioration of the concrete majorly occurs owing to the slow weakening and corrosion of different raw materials mixed with it during the time of construction.
