Concrete powder waterproof additive is a mixture with very fine particles insoluble in water, which spreads throughout its entire volume after mixing with concrete.
Due to the hydrophobicity of concrete powder waterproofing, the penetration of water, chemicals and sulfates is prevented, the durability of concrete increases against different atmospheric conditions.
Powder waterproofing reduces the permeability of concrete against water and corrosive chemical solutions by up to 80%.
Powder waterproofing is one of the advantages of using waterproofing, increasing the consistency and uniformity of concrete and increasing the speed of concrete setting by up to 10%, reducing the effects of corrosion, water leakage, and increasing the protection of rebars and reinforced structures.
Concrete powder waterproofing increases the life of concrete structures.
The low cost of materials and ease of implementation are two other advantages of waterproofing. For the production of all kinds of concrete, tanks, foundations, bridges, walls, roofs, etc. Chemical concrete powder waterproof is the best.
In dam construction and air and ground resources made of concrete, pools, concrete structures that need to be sealed. In places where freezing and thawing conditions prevail. It is used to make concrete impervious to chemical solutions and water for retaining walls, water channels, tunnels, bridges, ponds and for durable and long-term waterproof constructions.
The most important reason for the lack of resistance of concrete against water penetration and other chemical factors is the lack of necessary compression and the presence of voids in concrete. After mixing with concrete, chemical concrete powder concrete creates a hydrophobic crust (water-repellent) inside the pores, cavities and on the surface of the concrete, after mixing with the concrete, and it cuts off the connection of the fine channels inside the concrete with each other. It reduces its permeability.
The resulting layer has a stable property and besides the water repellency property, it increases the resistance of concrete against the invasion of sulfates and other chemical solutions.
Chemical concrete powder waterproof protects your structure against moisture. Although waterproofing systems make up a small part of the total cost of a building project, if the wrong solution is chosen or installed incorrectly, the cost of remediation can be very high.
Usually, the amount of water used in concrete is much more than the amount needed to hydrate cement. This excess water occupies space in the concrete and forms a network of capillary pores.
The best amount of consumption is determined by performing various tests in workshop conditions. The usual amount of consumption is 1 to 3% of the weight of cement used. Which is 3% at best.
It is better to mix it with the solid materials of the mortar first and then add the used water, otherwise it should be mixed for at least 10 minutes after adding it to the ready concrete.
(Due to the possible error of adding additives and the use of invalid additives in the concrete mix, it is not prepared to add all the additives on site.)
