JF CALCIUM FORMATE Product Description:

Synonym: CAS 544-17-2

Calcium formate is a kind of additive which has no erosive effect on steel bar. Its molecular formula is C2H2CaO4, which mainly accelerates the hydration of calcium silicate in cement and increases the early strength of cement mortar. The influence of calcium formate on strength of cement mortar mainly depends on the content of tricalcium silicate in cement. Tricalcium silicate is less, it will not attenuate the late strength of cement mortar, and there is a certain antifreeze at low temperature.

There are two main reasons for adding early strength agent to polymer mortar:

One is that some construction sites require a certain amount of construction, which should be strengthened earlier on the basis of early strength to meet the requirements of outdoor force. Second, when the temperature is low, the strength of the mortar slows down and will be affected. The strength of the mortar is low when it freezes. The more the mortar is beaten, the mortar will be frozen in the early low-strength period, so add the early strength agent at low temperature.

At low temperatures, even the addition of strength agents will reduce the strength of cement mortar. One is because the water conversion rate is slow when construction is performed in a low temperature environment, which affects the construction efficiency. When the temperature reaches the freezing point, the water turns into ice and expands in volume, making it easy to hollow out and fall off. After the two people went deep inside, the strength of the mortar was significantly reduced. During construction, icing occurred.

Naturally, the hydration reaction is a release, with a certain hydration temperature, the cement strength is reduced. If the welding temperature exceeds 0°C, the hydration reaction will continue and the strength of the once-cycle cement will decrease. The third is the general reheatable reaction powder reaction powder reaction. The molding temperature of EVA is above 0°C, while the temperature of EVA products is above 0°C, generally around 0°C. gender. Moreover, when the temperature is slow, the dissolution rate of salt particles is slower, and the adhesion and workability of the mortar are weaker. Therefore, the construction quality above 5°C can be guaranteed.
