. Product introduction
. -Chemical conversion expanded fiber Fiber is a cement-based dry powder material. The active substances it contains can react with unhydrated cement and hydration-active substances in concrete to form crystals and block concrete pores. Numerous high molecular polymer materials, modified fibers, inorganic materials and auxiliary materials, dry powder materials processed by special processes. It is a flexible anti-crack admixture specially designed for commercial concrete and commercial mortar. It has the characteristics of high shrinkage reduction, high crack resistance and high toughness.

. Working Principle
. - What plays a leading role is the active compound contained in it. The reaction product of this compound and calcium ions can migrate with water in the internal voids and cracks of concrete, and when it encounters cement and other water-soluble After oxidizing the substance, a chemical transformation occurs, forming calcium silicate crystals and blocking the gaps and cracks, reducing the porosity of the cement stone. The active compound returns to its original state after the conversion reaction and can continue to participate in the next round of reactions. The schematic diagram of the conversion reaction is as follows:
. Product advantages
. 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 concrete plastic shrinkage and drying shrinkage, reduce the risk of cracking
. Non-toxic, environmentally friendly and pollution-free
. Avoid high repair and maintenance costs.
. Scope of application
. It can be applied to all projects that require high durability of concrete. For concrete projects in harsh environments such as: civil air defense projects, tunnels, roofs, pavements, basement projects, etc., the effect is better. Significantly.
