Characteristics
Isocret is a liquid additive which gives concrete waterproof quality. The
product reacts chemically with the lime that is formed from hydration of
cement and creates salts which, on the one side, block capillary pores
but on the other side, give concrete hydrophobic properties. An important
quality of Isocret is that, compared to other additives of its category, it does
not cause reduction of the final resistances of concrete. (According to table
9 of standard ELOT EN 934 – 2 the reduction of resistance in compression
is allowed up to the scale of 15%).
The impermeability of concrete:
Water absorption through concrete is a multifaceted problem that is
analyzed in two steps:
a) The capillary absorption of water in simple contact (without
pressure) with concrete.
b) Pressured water penetration into concrete.
Standard EN 934-2: 2001 requires reduction of water absorption into
concrete to the extent of ≥ 40% by the addition of a waterproofing additive. Consumption: 300-500gr/100 Kg cement Packaging: 5 Kg / 20 Kg / 100 Kg plastic bottles
