国内已列入部标准的四种“早期推定混凝土强度”试验方法中,以促凝压蒸法的1小时为最快。可以说1小时促凝压蒸法已达到快、准、简的目标,尤其从速度上说达到了国际水平,但我们考虑以下两个问题: 1.对于集中搅拌站(包括商品混凝土厂)来说,搅拌一次1～2分钟,生产的混凝 Among the four “early presumed concrete strength” test methods that have been included in the Ministry’s standards in the country, one hour for procoagulant pressurization and steaming is the fastest. It can be said that the 1 hour procoagulation pressurization method has reached the goal of fast, accurate, and simple, especially in terms of speed, it has reached the international level, but we consider the following two questions: 1. For centralized mixing stations (including commercial concrete plants) Say, stir once for 1 to 2 minutes, the coagulation produced
