摘要
本文通过对不同配比特细砂砌筑砂浆7d和28d抗压强度的试验研究,分析了7d与28d强度的抗压强度的相关关系,得出的关系式对砂浆施工生产和施工中的强度控制以及砂浆配合比调整的辅助设计具有现实指导意义。
Through the experimental study on the 7d and 28d compressive strength of super-fine sand masonry mortar with different mix proportions, this article analyzed their correlations, and the relation formula can provide guidance for mortar construction, quality control and mix proportion adjustment.
