摘要
阐述了超时缓凝现象的概念;试验研究了超时缓凝混凝土的特征,包括混凝土凝结时间、抗压强度和塑性收缩;并结合工程实例,提出了预拌混凝土超时缓凝现象的判断和处理方法。为今后处理预拌混凝土的超时缓凝质量问题提供了技术参考。
This paper described concept of overtime retarding, experimental researched on features of overtime retarding concrete which included setting time, compressive strength and plastic shrinkage of concrete, then presented judgment and treatment methods of overtime retarding in ready mixed concrete combining with engineering example.This can be as a reference of overtime retarding concrete engineering problems.
