速凝剂凝结时间和抗压强度测定方法

The Measuring Method of Setting Time and Compressive Strength of Accelerator

总结了速凝剂检测工作中存在的问题,通过设计试验方法,将无扰动试验方法测得的凝结时间和抗压强度结果与标准试验方法测得的结果对比、分析,得出测定初凝时间小于1.5 min的速凝剂宜采用无扰动试验方法,给出了检测过程中的注意事项和建议。

This paper summarizes the practical problems existing in the detection of accelerator for shotcrete.Through the design of test method,the setting time and compressive strength measured by undisturbed test method are compared and analyzed with the results of standard test method.Finally,the result show that the undisturbed test method is suitable for the accelerator with initial setting time less than 1.5 min,as well as the precautions and suggestions in the detection process are proposed.
