Self-healing inorganic proliferation waterproof agent is a natural inorganic waterproof material with mainly amorphous active silicon, supplemented by hydration thermal inhibition components and micro-expansion components, and has the function of "thickening, crack prevention, seepage resistance, crack self-healing, improve durability" and other functions.This special active silicon combined with calcium hydroxide in cement, with the help of air water or water source, generation of calcium silicate crystal, produce insoluble branch and vine crystal in the concrete pores and capillary pipeline, increase the density, improve the durability of concrete, this repeated reaction, reproduction function, so that the concrete temperature crack, shrinkage crack get self-healing, thus achieving a permanent waterproof and cracking effect.Added quantity is 1% (concentrated type) and 3% (standard type) of the cement quality.

The waterproof mechanism of the self-healing inorganic proliferation waterproofing agent is to generate calcium silicate crystals with the help of water and the reactant calcium hydroxide. While preventing the loss of free calcium hydroxide, the colloid continues to multiply and fills the gaps in the water channel, forming a high-density impermeable body structure, thereby achieving the effect of structural waterproofing.

 

The main reason for the deterioration of concrete material performance is its exposure to a corrosive environment, in which chloride ions and sulfate ions are considered to be the main chemical corrosive media that affect the durability of concrete. The damage mechanism and residual strength of concrete in a chemical medium environment have attracted the attention of material experts and structural experts. In water conservancy projects and waterproofing projects, impermeable concrete plays an important role. People constantly change the performance of impermeable concrete by adjusting admixtures, concrete mix ratios, etc. to meet engineering needs. With the continuous development of materials science, nanomaterials are increasingly valued in the field of concrete. Adding nanomaterials can effectively increase the service life of concrete and improve the mechanical properties of concrete. Therefore, nanomaterials are currently widely used in the construction of hydraulic structures, underground structures, roads and bridges, etc.

Self-healing test design
standard concrete impermeability test mold is formed, and 12 impermeability test blocks are formed, namely the reference test block, 3% test block, 5% test block, and 7% test block. Test method
The second permeability pressure
of all impermeability test pieces is tested after 14 days of curing. After the first impermeability test, the mold is continued to be cured in water under standard curing conditions for 28 days, and the second impermeability test is carried out to measure the impermeability pressure.

The proliferator is alkaline like concrete, so avoid direct contact with the skin and avoid getting into the eyes. Wear rubber gloves when mixing dry powder or wet materials by hand.

 

The finished products need to be stored in a dry environment, pay attention to ventilation, avoid squeezing and collision, and keep away from fire and heat sources.
