What is concrete waterproofing agent?

Overview of concrete waterproof admixture

A concrete waterproof admixture is a chemical admixture added to the cement. After the cement is hardened, its volume will expand to compensate for the shrinkage and tension of the steel bars, thereby generating prestress and completely filling the cement gap. It can be directly incorporated into the bottom surface of the cement waterproofing agent product to form an excellent hydrophobic layer. When water splashes on the surface, it will roll off in the form of water droplets, acting as a lotus leaf. The mixture of water and foam is called a pre-foaming solution. The pre-foaming solution and compressed air are supplied through a spray gun.

What is a concrete waterproofing agent?

A concrete waterproof additive is a kind of chemical admixture added to the cement. When the cement solidifies and hardens, the volume expands and plays a role in compensating for shrinkage and tensioning the steel to generate prestress and fill the cement gap. Waterproofing agent, also known as waterproofing essence, plugging king, plugging spirit, and new waterproof material, is divided into two kinds of organic and inorganic. It is a new type of high-tech waterproofing product. The advanced fatty acid type mortar waterproofing agent has the characteristics of long waterproof life, wide application range, simple construction, low cost, safety, and environmental protection (reaching oral non-toxic level). Its executive standard is jc474-2008 (mortar, concrete waterproofing agent) standard.

What is the performance of the cement waterproofing agent?

1. The calcium sulfoaluminate expansion agent component of this product is very effective in compensating for the shrinkage of concrete to achieve crack resistance; the ultimate expansion rate of concrete after 14 days of curing in water is ≥0.015%, while general waterproofing agents can only resist water seepage. Will crack.

2. The superplasticizer of this product can reduce the water-cement ratio of concrete and improve concrete's workability and compactness, thereby further reducing the shrinkage of concrete, filling the internal porosity of concrete, and improving permeability and high strength. Concrete.

3. The product changes with the construction season, compound retarder, and other ingredients. With lower concrete hydration heat, temperature difference cracks can be reduced. Mass concrete can be poured, summer construction concrete, or early strength agent or antifreeze can be added, and early strength anti-freezing and anti-cracking concrete can be added cast in winter.

4. Reinforced concrete structures over 60m should be constructed using the shrinkage-compensating concrete of this product, and no post-pouring tape should be left behind. Instead of post-casting belts, expansion reinforcement belts should be used for continuous casting of concrete. It can solve the trouble caused by cleaning and gouging after casting the joint. It solves the problem that the joint must be poured within 60 days after pouring, the construction period is long, and the a hidden danger of water leakage.

What are the classifications of cement waterproofing agents?

1. Leather waterproofing agent

2. Textile waterproofing agent

3. Mortar waterproofing agent

4. Silicone waterproofing agent

Application of concrete waterproof admixture

Concrete waterproofing agent significantly improves the impermeability and waterproof function of concrete, and the impermeability reaches P25 or more. It also has the effects of retardation, early strength, water reduction, and crack resistance, and can improve the workability of fresh mortar. Can replace lime slurry. It is used for waterproofing projects in basements, toilets, water storage tanks, purified water tanks, tunnels and roofs, roofs, floors, walls, etc. It is especially suitable for bungalow roof concrete, large-volume waterproof concrete, hydraulic concrete, waterproof mortar, etc., which can completely solve the roof Problems with water leakage, damp walls, and groundwater leakage. The cheapest, ideal, and reliable material of choice in China.
