大体积混凝土表面保温程序的开发与应用

Developmcnt and Application of Mass Concrete Surface Heat Preservation's Procedure

大体积混凝土表面保温是防止混凝土表面出现裂缝的重要措施,而混凝土保温又涉及到诸多因素,以寒潮期问的保温为例,论述了大体积混凝土表面保温系统的开发过程,并以沙老河拱坝为算例,分析了表面保温的要求与意义,可供工程参考应用。

Mass conterete surface's heat preservation is an important nieasure to prevent concrete surfacecracking. But concrete heat preservation is influenced by many factors , as a example of heat preservation dur-ing cold wave, this paper discusses the development of the mass concrete surface' heat preservation sys-tem. Traking Shalaohe Arch Dam for computing example, the demand and significance of concrete surface heatpreservation are analyzed. The result is valuahle for engineering.
