筏板基础砼施工中温度控制技术应用

Application of Temperature Control Technique to Concrete Construction of Raft Foundation

针对筏板基础大体积砼浇筑、初凝过程中出现的温差以及砼的搅拌、输送、浇筑等方面的问题,从配合比的设计、掺加剂的应用、砼温度控制等方面作了阐过,给出了"双掺"技术的社会经济效益.

According to some problems on temperature difference and stir,transfer and pour of concrete in process of pour and initial set for large volume concrete of raft foundation,the design of combining proportion,application of adulterating agent and temperrture control of concrete are ex- pounded.And social economic benefits of'double adulteration'technique is given.
