摘要
在约束条件下对再生骨料钢筋混凝土剪力墙和普通钢筋混凝土剪力墙进行了干燥收缩应变测试,同时观察墙体表面干燥收缩裂缝产生的情况.结果表明:2种剪力墙内部收缩应变均明显小于相应的外表面收缩应变;2种剪力墙内部收缩应变相差不大;再生骨料钢筋混凝土剪力墙外表面收缩应变明显比普通钢筋混凝土剪力墙小,而细微收缩裂缝则明显增多.
Drying shrinkage strains of recycled aggregate reinforced concrete shear wall and common reinforced concrete shear wall were measured under constraint conditions,and cracks situations on shear wall surface were observed.The results reveal that for recycled aggregate reinforced concrete shear wall and common reinforced concrete shear wall,the internal shrinkage strain are obviously less than surface shrinkage strain.There is a little difference of internal shrinkage strains between recycled aggregate reinforced concrete shear wall and common reinforced concrete shear wall.The surface shrinkage strain of recycled aggregate reinforced concrete shear wall is obviously lower than that of common reinforced concrete shear wall,while micro shrinkage cracks is obviously more than the latter.
