通过研究抹灰砂浆立方体抗压强度与砂浆碎粒筒压比之间的相关性,建立了筒压法测定抹灰砂浆抗压强度测强曲线,测强公式为指数函数Y=-0.06+1.19e^(4.48x),适用条件:筒压荷载25kN~30kN;测强范围3.3MPa~31.6MPa。

By studying the correlation between the cube compressive strength of plastered mortar and the cylinder compression ratio of mortar fragments,the cylinder compression method is used to measure the compressive strength of plastered mortar.The formula for strength measurement is exponential function Y=-0.06+1.19e^(4.48x),and the applicable conditions are cylinder pressure load of 25kN~30kN and strength measurement range of 3.3MPa~31.6MPa.
