本方法采用GB177—85规定配比及用量的水泥胶砂,加入专用促换凝剂,经搅拌,振动成型后,立即将带模的试件放入压蒸锅中压蒸养护1.5小时.试件压蒸养护后立即折模进行抗压强度试验,以测得快硬胶砂强度值,根据巳建立的同材料的水泥胶砂强度推定式,推定出标准养护28天令期的水泥胶砂抗压强度值.
In this method, cement mortar with the ratio and amount specified in GB177-85 is used. After the special coagulant is added, the sample with the mold is placed in an autoclave and steamed and cured for 1.5 hours immediately after stirring. . Immediately after pressurization and curing of the test specimens, compressive strength tests were conducted on the folded molds to determine the strength values of the quick-hardening rubber sands. Based on the formula for determining the strength of the cement mortar used for the same material, a cement mortar with a standard curing period of 28 days was deduced. Sand compression strength value.
