大体积混凝土施工中表面保温

Thermal isolation on surface of mass concrete work in construction

对于严寒地区寒潮是大体积混凝土产生裂缝的主要原因。因此 ,表面保温尤为重要 ,本文从寒潮引起的混凝土表面温度及应力变化讨论了大体积混凝土的表面保温及防裂问题。

In cold region, crevices emerged on the surface of mass concrete because of cold waves. It is important to keep the surface temperature in construction. The problems on thermal isolation and crevices prevention are discussed based on analysis of surface temperature and stress change due to cold waves.
