随着建筑工业与结构设计理论的发展,要求能及时地评定与控制混凝土的质量。因此,研究早期推定混凝土强度的试验方法,以便能于早期判定混凝土强度质量,就显得十分必要。专题组三年来先后进行了密封试模干热养护、蒸汽养护、温(热、沸)水养护及脱模试件热水养护、沸水养护等加速养护方法(不同养护温度、不同养护制度、当日试压、次
With the development of the architectural industry and structural design theory, it is required to be able to evaluate and control the quality of concrete in a timely manner. Therefore, it is necessary to study the experimental method for estimating the strength of concrete in the early stage so that the strength of the concrete can be determined early. During the three-year period, the special group has successively conducted heat preservation tests for sealed test molds, steam curing, conservation of warm (hot, boiling) water, and hot curing of demoulding test specimens, boiling water conservation and other accelerated maintenance methods (different curing temperatures, different curing systems, and Test pressure, times
