高温长运距喷射混凝土坍落度损失问题解决方法研究

Study on Slump Loss for Shotcrete under the Conditions of High Temperature and Long Distance Transportation

如何减小高温长运距喷射混凝土坍落度损失是工程施工中需要解决的一个难题,通过大量的室内及现场试验,采用更换特定的外加剂、改装转运小车等方案,成功解决了巴基斯坦某工程中喷射混凝土在高温长运距运输中坍落度损失的问题。

It is relatively difficult to solve the problem of slump loss for shotcrete under the conditions of high temperature and long distance transportation. By conducting a large number of indoor and site tests, and adopting specific admixture and modifying the transfer vehicles, the problem of slump loss of shotcrete in a Pakistan＇s project is successfully sloved.
