摘要
高性能混凝土因水胶比低、自收缩大且主要发生在早期 ,而目前对于早期自收缩的测量还没有统一标准可依。在对比和分析国内外自收缩测量方法的基础上 ,提出了一种新型非接触式测试方法。该方法测量精度高 ,适用范围广 。
The autogenous shrinkage of HPC develops greatly and mainly during early age due to a low water binder ratio,but there is no standard test method for early autogenous shrinkage of the concrete.On the basis of comparing and analyzing some measuring means of autogenous shrinkage at home and abroad,one new experimental technique having no need of contacting is advanced in this paper.This technique is applicable in a large scope with a high precision,and it overcomes the deficiencies of measuring early shrinkage of concrete with other methods.
