摘要
贵州省内的商品混凝土所用骨料基本上为山砂、碎石,为使剪压法更适用于检测本地区的混凝土抗压强度,通过采集大量的实验数据分析推导出抗压强度与剪压力之间的数学关系,建立了地区测强曲线。通过在贵州省内的五个实际工程中的应用表明此地区测强曲线比统一测强曲线具有更高的适用性。
The aggregate used in commercial concrete in Guizhou province is basically mountain sand and gravel. Inorder to make the shear pressure method more suitable for testing the compressive strength of concrete in the area,the mathematical relationship between the compressive strength and shear pressure are derived by collecting a largeamount of experimental data, and the regional strength curve is established. The application in the five practicalprojects in Guizhou province shows that the intensity curve in this area has higher applicability than the uniform in-tensity curve.
