摘要
混凝土收缩变形是导致混凝土结构产生非荷载裂缝的主要原因,本文简单概述了混凝土非荷载裂缝产生的原因及其收缩机理,描述了混凝土减缩剂的国内外研究进展,并对减缩剂的化学结构、组成和掺量等问题进行了阐述。
The early - age concrete shrinkage deformation is the main reason to produce the non - load cracks of concrete structure. The reason for concrete non - load cracking and shrinkage mechanism are simply outlined in this study. The research and development on shrinkage reducing admixture for concrete are chiefly accounted. And the chemical structure, component and content of SRA are also given in this article.
