摘要
Abstract
The effect of different constant temperature and humidity conditions on the drying shrinkage of concrete are analyzed,and the improvement of crack resistance of concrete with different curing materials and different content under the condition of large temperature difference are explored.The results show that high temperature and high humidity will promote the internal water loss and intensify the drying shrinkage of concrete.In order to ensure the stability of concrete structure,appropriate temperature and humidity conditions should be maintained in engineering construction.Adding SAP and diatomite into concrete can promote the hydration reaction of cement,improve the compactness of concrete,and thus improve the compressive strength and splitting tensile strength of concrete.关键词
