explanations:
Concrete with the right mix design, quality stone materials and a suitable water to cement ratio is largely impermeable, but small joints and cracks and pores and other defects that occur during the construction and execution of concrete reduce the strength. It resists the penetration of water and other solutions. The use of a suitable water-proofing material without creating an adverse effect on the concrete gives it water repellency and relative insulation. RW Waterproof additive after mixing with cement and water in hydrophobic crust concrete (hydrophobic) inside the holes And on the concrete surface and cuts the connection of small ducts inside the concrete with each other and reduces the permeability. The resulting crust has a stable property and in addition to creating hydrophobic properties, it also increases the resistance of concrete to the intrusion of sulfates and chemical solutions. 122 matches.
