water proof ,leak proof, crack proof, concrete hardener and corrosion resistant to the steel in R.C.CCONCARE-XL is a very powerful liquid admixture compound extracted from algae. They are long chain carbohydrate biopolymer and its salts are hydrocolloids (materials that bind or absorb water). CONCARE-XL is acid stable and heat resistant. CONCARE-XL is manufactured to the Indian standard of IS 2645. CONCARE-XL as chloride and sulfate free.CONCARE-XL is free from chloride and sulfate. It can be applied to any type of construction work. Versatile use of CONCARE-XL admixtureCONCARE-XL is versatile admixture used in cement construction as a waterproof, weather proof, crack proof and as concrete hardener. 200ml of CONCARE-XL is recommended for 50kg of cement. CONCARE-XL can be used for all types of cement. CONCARE-XL prevents segregation of aggregates in the mix and improves the cement strength. How CONCARE-XL works.On usages of CONCARE-XL water can be reduced dramatically for the type of mix and usage. Around 10%-20% of water is reduced and presence of cohesiveness in CONCARE-XL increases the workability of the mix. Water plays important role in concrete structure. When minimum water is used in the mix cement strength increases and decrease in porosity. The fig shows the strength of cement due change in water cement ratio. CONCARE-XL as crack proof, water proof and corrosion resistant.On the application of CONCARE-XL admixture, the natural accelerator increases the cement bonding by changing the cement into gel form, which decreases porosity.Thus gel formed cementious liquid gets hardened preventing formation of cracks and increases the durability of concrete.Presence of CONCARE-XL in the concrete forms a coating over the surface of steel rods and prevents corrosion. CONCARE-XL admixture controls the rate of hydration there by eliminates the surface cracks, on vertical application where proper water curing cannot be done.
