摘要
SG系列高效建筑砂浆外加剂是一种新型的水泥砂浆拌合物外加剂,掺入后不仅能改善建筑砂浆的和易性和保水性,而且能明显提高砂浆的各项性能指标.详细地介绍了掺SG外加剂建筑砂浆的性能指标,并与末掺外加剂的砂浆作对比.
Through observing construction cites and reading works on concrete, this paper analyzes the reasons of concrete crack, explores the methods of temperature controlling and measures of preventing concrete from cracking.
