混凝土砖墙体特细砂水泥砂浆筒压法检测抗压强度的试验研究

The experimental study of concrete brick wall special fine sand cement mortar cylinder pressure method compressive strength

按照国家标准GB/T50315—2011规定的筒压法原理和检测方法,对混凝土砖墙体中特细砂水泥砂浆的现场检测进行了试验研究,通过对模拟墙体的同条件养护砂浆立方体抗压强度与墙体砌筑砂浆筒压指标的相关分析,拟合了推算混凝土墙中砌筑砂浆抗压强度的计算公式。

In accordance with the provisions of the national standard GB/TS0315-2011 cylinder pressure method and detecting principle,on site inspection of concrete brick wall special fine sand cement mortar were studied,by analyzing simulated wall with the same curing condition mortar compressive strength and wall masonry mortar cylinder pressure index, fitting the regression calculated formula the compressive strength of masonry mortar, can be applied.
