C - Max (Water Proofing)

C-MAX is a Cement Admixture manufactured under license from Dr. Volker in der Weische, Germany conforming to IS 2645:2003 for Integral Waterproofing Admixture and IS 9103:1999 for Water reducing admixture.

C-MAX is a solution of micro fines mineral particles as well as some Nano ceramics in Phenolic Acrylates. This is a proprietary product of SRL, developed in co-operation with Dr. Volker In der Wiesche, Germany. These Nano ceramics and micro fine materials give additional strength to the concrete Block.

Excess quantity of water used during construction period leads to defect in the concrete. If more water is added, it will evaporate and will lead to voids in the concrete, thereby making the concrete weaker.

By adding C-MAX, water demand in the cement is reduced and the cement colloids travel to fill up all the voids and produce a compact and dense concrete mass.

Cement is basically a chemical, having various proportions of Di-Calcium Silicate (DCS) and Tri-Calcium Silicate (TCS). Grade-33 type of cement contains 33% TCS and Grade-43 type of cement contains about 43% TCS. Higher TCS containing material needs colder climates and Grade 53 type of cement is used more in construction of dams etc, because, they are basically high heat generation cement and they work better and give more strength in under water condition or in high humid conditions. In Indian condition, where temperature variation is extreme, it is always better to use moderate heat generating type of cement, like Grade-33 type. Grade-33 type does not mean that, strength in the structure will be less. But, it will ease the use and will not generate more heat during use. So, less water is required and so, you also save on the cost of the material, which cement manufacturers charge for Grade-53 type. It is very interesting to know that, the chemical composition of the cement irrespective of their grades, world-over remains the same. The general chemistry is as under:

  • CaO : 64% ± 4%
  •  SiO2 : 22% ± 1%
  •  Al2O3 : 6% ± 1%
  •  Fe2O3 : 5% ± 2%
