From the point of materials stability, the practical application possibility of recycled aggregate concrete used in reinforced concrete shear wall is investigated, as one of effective methods to use recycled aggregate. The research focuses on the drying-shrinking crack of reinforced recycled concrete shear wall under constraint conditions. Drying-shrinking strains and cracks of reinforced concrete shear wall and common reinforced concrete shear wall were measured with surface bonded strain gauge and internal buried gauge under constraint conditions, respectively. The results reveal that internal shrinkage strain is obviously less than surface shrinkage strain, and there is a little difference of internal strains between reinforced recycled concrete shear wall and common reinforced concrete shear wall. However, shrinkage strain of common reinforced concrete shear wall is higher than reinforced recycled concrete shear wall, while, micro cracks of recycled concrete is obviously higher than common concrete.
