摘　　要：文中通过采用不同的养护方法对达到养护龄期的混凝土试块进行强度测试,简单地整理和分析了采集所得到的数据,总结其中规律,初步确定了温水养护法,即90℃养护2d更能准确预测出28d标养强度,同时通过建立数学模型得到两者之间的关系,可以大致提前预测判断混凝土强度等级是否满足设计要求。This paper uses different maintenance methods to test the strength of concrete test blocks that have reached the maintenance age,collects the data obtained for simple collation and analysis, summarizes the rules, and preliminarily determines the warm water conservation method, that is, 90℃ maintenance 2d can more accurately predict the 28d standard maintenance strength;at the same time, the relationship between the two can be obtained by establishing a mathematical model, and the strength level of the concrete can be predicted in advance to determine whether the strength level of the concrete meets the design requirements.
