CAA chemical conversion type fiber expansion anti-crack waterproofing agent

Chemical conversion type fiber expansion anti-crack waterproofing agent
Implementation standard "Mortar, concrete waterproofing agent"
Product introduction
Chemical conversion type fiber expansion anti-crack waterproofing agent contains many polymers It is a kind of cement-based dry powder material processed by special technology, including physical materials, modified fibers, inorganic materials and auxiliary materials. The active substances it contains can react with unhydrated cement and substances with hydration activity in concrete to form Crystallizes and blocks concrete voids. Greatly improve the impermeability, impact resistance and earthquake resistance of mortar and concrete. 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. This fiber contains hundreds of millions of fibers per cubic meter in mortar and concrete, and is evenly and disorderly distributed in any direction of the mortar and concrete, just like hundreds of millions of micro-rebars embedded in the mortar and concrete, greatly improving In order to enhance the effect, it can significantly improve and enhance the impermeability, crack resistance, impact resistance, wear resistance, frost resistance and earthquake resistance of mortar and concrete. The incorporation of materials such as microsilica fume and waterproofing agents also improves and enhances the quality of mortar and 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 migrate with water in the internal porosity and cracks of concrete, and when it encounters cement and other water After oxidizing the substance, a chemical transformation occurs, forming calcium silicate crystals and blocking pores and cracks, reducing the porosity of the cement stone.
Product Features
, Significantly improve the waterproof and impermeability properties of concrete
, Reduce the porosity of cement stone, improve the freeze-thaw resistance of concrete
, Effectively avoid corrosion of steel bars
, Reduce The plastic shrinkage and drying shrinkage of concrete reduce the risk of cracking
, are non-toxic, environmentally friendly and pollution-free
, and avoid high repair and maintenance 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.
, Large volume mortar and concrete pouring, such as conversion beams, columns and floor slabs of docks and high-rise buildings.
, roof treatment of industrial and civil buildings, basement waterproofing, interior and exterior wall plastering mortar.
, powder building materials, concrete mixing stations, commercial concrete, construction dry mortar, anti-cracking mortar, thermal insulation mortar, etc.
Pavement guardrails for roads, bridges and highways.
Concrete pouring for dams, pools, swimming pools, parking lots, airport runways and aprons.
Shotcrete for tunnels, mines, culverts, subways, slopes, etc.
, corrosion-resistant sites on coastal beaches, dams, saline-alkali zones, and chemical plants.
, making concrete components, European components, and urban art sculptures. Pipes, plates, fiber cement products.
, lightweight partition walls, panels, insulation panels, decorative panels, etc.
