Desc:The function of the early strength agent is to accelerate the hydration process of the cement under the condition of the existence of the liquid phase in the concrete, and improve the early strength. In winter, considering the effect of low temperature on the material, and the surface covering repair operation is relatively long, material freezing is likely to occur during the operation. Therefore, calcium formate has the advantages of simple operation, good maintenance, and good frost resistance and abrasion resistance, and can complete the repair construction of cement pavement sand.
