【摘要】 介绍了一套用于混凝土及砂浆环形试验的试验装置和用于推测处于约束状态下的混凝土及砂浆出现开裂的可能性的数据计算与分析方法。根据混凝土及砂浆试件在开裂时的应力变化率和相应的开裂龄期对开裂的可能性进行合理推测更多还原

【Abstract】 A testing cell for ring test of concrete and mortar is introduced in this paper,and a data analysis procedure is developed for cracking likelihood forecast of concrete and mortar under restrained shrinkage.The cracking likelihood can be expected on the basis of either how long it takes the material to crack or the tensile stress rate in the materials.更多还原
