After pouring, the cementitious material hydration heat in cement base causes temperature to increase in turn, in the case where volume of concrete is larger, gathers
The heat of hydration of collection inside it is not easy to distribute, and internal temperature increases, but surface temperature is very fast and relatively low because radiating, so holding
The inside and outside significant temperature difference is easily caused, concrete surface is made to form temperature tensile stress, meeting lower in early stage tensile strength
Crack is formed in mass concrete surface, crack can not only reduce the bearing capacity of structure, but also to the waterproof of structure, anticorrosive
Etc. performances generate large effect.Therefore, it is necessary to the raising of the internal temperature of mass concrete be controlled, to reduce inside and outside it
The temperature difference reduces structural cracks.

Latent heat；When phase-change material cools down, the heat of storage will be dispersed into environment within the scope of certain temperature, be carried out from liquid
State is to solid reverse transformation.In both phase transition process, stored or release energy is known as latent heat of phase change.Physical state is sent out
