最近,我到一些工地检查工程质量,发现不少施工单位在制作石子最大粒径≤30毫米混凝土抗压强度验件时,都是使用150×150×150(毫米)的试模,试验工作量相当大。问他们为什么不使用小一点的100×100×100(毫米)试模时,回答几乎是一致的:100×100×100(毫米)试模不是标准试模,试验出来的结果不标准,不可靠。一些新近出版的技术书刊,也只强调 Recently, I went to some construction sites to inspect the quality of the project and found that many construction units use 150×150×150 (millimeter) test dies when making stone aggregate compressive strength test pieces with a maximum grain size ≤ 30 mm. quite big. When asked why they did not use the smaller 100×100×100 (millimeter) tryouts, the answer was almost identical: 100×100×100 (millimeter) test dies were not standard test dies. Test results were not standard and unreliable. . Some newly published technical publications also emphasize only
