早期推定混凝土强度加速养护试验方法,先后在西安、贵阳、武汉、保定、柳洲、北京、上海、沈阳等八个地区试验。进行了五个品种三个标号水泥,两种骨料,三种外加剂配制不同水灰比的混凝土的试验研究,探讨了不同加速养护方式、不同养护温度和不同养护制度的各种试验方法对早期推定混凝土强度的效果,最后提出沸水法、热水法、温水法三种试 Early presumed concrete strength accelerated curing test methods were successively tested in eight regions such as Xi’an, Guiyang, Wuhan, Baoding, Liuzhou, Beijing, Shanghai and Shenyang. Five types of three grades of cement, two kinds of aggregates, and three types of admixtures were used to prepare concretes with different water-cement ratios, and various test methods for different accelerated maintenance methods, different curing temperatures and different maintenance systems were discussed. Early estimation of the effect of concrete strength, and finally the three methods of boiling water method, hot water method and warm water method were proposed.
