Chemically converted fiber expansion anti-cracking waterproofing agent
> br r rr
>Execution standard: "Mortar Concrete Waterproofing Agent"
>Product Introduction
>Chemically converted type Fiber expansion anti-crack waterproofing agent contains many high molecular polymer materials, modified fibers, inorganic materials and auxiliary materials. It is a cement-based dry powder material processed through special technology. The active substances it contains can react with unhydrated concrete. The cement reacts with hydration-active substances to form crystals and block the voids in the concrete. It greatly improves the impermeability, impact resistance and earthquake resistance of mortar concrete. The concrete has the characteristics of high shrinkage rate, high crack resistance and high toughness. The fiber in the product uses high-strength and high-modulus polyvinyl alcohol fiber whose tensile strength and elastic modulus are several times or dozens of times higher than that of the modified fiber. The fiber contains hundreds of millions of fibers per cubic meter in the mortar concrete, and is evenly and disorderly distributed in any direction of the mortar concrete, just like hundreds of millions of micro-rebars embedded in the mortar concrete, which greatly improves the reinforcement effect. function, thereby significantly improving and enhancing the permeability, crack resistance, impact resistance, wear resistance and frost resistance of mortar concrete and improving the earthquake resistance. The incorporation of materials such as microsilica fume and waterproofing agents also improves and enhances the quality of mortar concrete in different aspects.

>Working Principle
>What plays a leading role is the active compound contained in it. The reaction product of this compound and calcium ions can be mixed with water in the The internal porosity and cracks of concrete migrate. When encountering cement and other hydrated substances, chemical transformation occurs, generating calcium silicate crystals and blocking pores and cracks, reducing the porosity of cement stone.
>Product Features
>Significantly improve the waterproof and impermeability properties of concrete
>Reduce the porosity of cement stone and improve the freeze-thaw resistance of concrete
>Effectively avoid corrosion of steel bars
> Reduce the plastic shrinkage and drying shrinkage of concrete and reduce the risk of cracking
>Non-toxic, environmentally friendly and pollution-free
>Avoid high maintenance and repair costs.
>Scope of application
>It can be applied to all projects that require high durability of concrete. The effect is more significant for concrete projects in harsh environments such as civil air defense projects, tunnels, roofs, pavements, basement projects, etc.
