Specialization of Cement Reinforcing Agent ZOC-BT4

Reduce hydration heat

KFA promotes the breaking down of cement particles, and the heat released by hydration is lower than that of ordinary concrete. At the same time, some of the heat released by KFA is absorbed and utilized during the oxidation of metal elements, so the hydration heat energy is reduced.

Reduce shrinkage cracking of ZOC-BT4

The water consumption is reduced by 10-20%, the electrolyte is high, the cement slurry increases by more than 10%. The free lime Ca (OH) 2 reacts to form a high consistency crystal liquid, which is not easy to precipitate and is not easy to secrete water. The slurry evaporation speed on the surface of the high electrolyte cement paste is slow, and the crystallization liquid can grow into crystal in the stable volume cement slurry, which can reduce the shrinkage and cracking.

Permeability of ZOC-BT4

When the cement reacts with KFA, light acetylene gas will be released. The gas will be released from the concrete surface quickly, which will reduce the total porosity. The pores contain 97% of the coarse pores and 3% coarse pores, and the voids are fine and few. Generally, carbon dioxide is produced in concrete. The bubble needs to accumulate to the critical mass before the large void can be formed from the concrete surface. Generally, it contains 70% coarse and 30% fine pores

The reaction of plaster with KFA results in calcium aluminate crystal, which is insoluble and chemical resistant. During hydration, it grows along the capillary wall to form hexagonal dendrite. When the liquid goes deep, the hexagonal dendrite expands and reduces the diameter of the pores. The diameter of the pore decreases, which can increase the hydraulic pressure and pressure in the pores. The positive pressure produced by the pore can resist the infiltration of gas, liquid and other electrolyzing chemical solutions such as salt, acid, alkali, industrial waste liquid, sugar acid and oil. At the same time, water, acid. The self tension of alkali chemical liquid, petroleum and other liquids can not penetrate into the micro pore. Although the pore is very small due to the expansion and contraction of crystalline body, it still has air permeability.

 Chemical resistance of ZOC-BT4

The metal elements in cement produce oxidation, which will form active metal ions with charge. The metal ions with charge and chemical liquids with electrolytes, such as corrosive liquids, react with each other on the surface of concrete to resist the erosion of chemical substances. Their chemical resistance is better than acid cement or high aluminum cement, and has corrosion resistance.

Reduce water consumption of ZOC-BT4

 

The higher the electrolyte, the faster the hydration speed of cement, the more the cement slurry, the better its working degree. Therefore, the water consumption must be reduced to maintain the best electrolyte strength and produce the most cement mortar. Main uses:

It is waterproof and can be used for underground buildings, such as subway, MRT system, tunnel, underground continuous wall, underground parking lot, underground sidewalk, elevator pit. Reservoir, swimming pool, water guide pipe, high impermeability shaft, culvert. High impermeable water drainage roof, building floor, high impermeable mortar moisture-proof layer, mortar waterproof layer.

It has acid resistance and chemical resistance, and can be used for:

Sewage treatment tank, acid storage tank, oil tank. Acid resistant terrace, chemical factory building, near beach dike, wharf, freezing room, etc.

It has the anti freezing and thawing property, and can be used in the freezing room, air-conditioning room, places with great temperature change and so on.

It can be used for buildings, dykes, docks and other projects near the sea.

The heat of bottom hydration and shrinkage cracking of the bottom can be used for reservoir concrete, dam concrete mortar layer, bridge concrete mortar layer, concrete pavement, etc.
