As we all know, to build a house naturally requires the use of cement, so as to better stabilize the foundation and the entire building. However, with the continuous advancement in the level of science and technology, there has been a new type of cement addition agent on the market, which is said to improve the product performance of cement and increase the strength of cement. Then, what are the advantages and benefits of using this additive in construction projects? Next, we will explain it to you by Xiaobian.
1, the advantages of cement enhancer
Before understanding its role, first understand the main components of the cement enhancer , including: 8% to 15% of diethylene glycol, 15% to 20% of starch syrup, 3% to 5% of glycerin, 2 % to 4% of triethanolamine, 2% to 4% of anhydrous sodium sulfite, in addition to a small amount of water.
In fact, the advantages of the product include: no need to use additives such as sand ash, fly ash, strong plasticizers, water reducers and bulking agents, eliminating the need for multiple processes. When the temperature is too high, only a small amount of water can be used for curing one or two times; no curing agent is needed. And it doesn't have to leak water and it's not easy to precipitate. There is it in the high-pressure spray operation, easy to pump and easy to plug, each thickness of up to 7-8 cm, rebound less than 5%. In addition, the construction temperature does not affect the condensation time at negative 5-40°C, and the construction time can be increased.
2, the role of cement enhancer
a, reduce the amount of shrinkage can reach more than 2 times, so it has good crack resistance.
b. Reduce the heat of hydration by 30-50% and reduce the temperature differential shrinkage and cracking.
c. Reduce water consumption by 10-20%, which means that the amount of cement in the formula can be reduced.
d. Increase the compressive strength by 20-25%, tensile strength by 40%, freeze-thaw resistance by more than 30%, reach over 350 cycles, and resist rupture strength by over 60%.
e, can resist 14 atmospheric pressure, that is more than 200psi water pressure, with impermeability.
f. reacts with lime Ca(OH)2 to form crystals, inhibit alkaline reactions, avoid crystallization, whitening, sanding and other phenomena.
g. Resist erosion and damage of seawater and chloride ions in the air and prevent corrosion of steel bars.
h. It can also improve the abrasion resistance of the concrete surface, making the work surface cleaner; and reducing the reaction with carbon dioxide to produce concrete neutral. Concrete contains 97% microcapillaries and 3% coarse pores. The total porosity decreases and the density can increase to 20-25%.
Xiao Bian concludes: For the strength of cement enhancer products and the use of it in the end what is introduced to this, I believe we look at the relevant knowledge in the above, the new building materials have a better understanding of the future When you want to build a new house, whether it needs to use this additive or not, you can make a choice.
