一、前言采用成熟度法,可予测混凝土强度,确定最佳拆摸时间,记录混凝土标准试件的温度一时间,此温与基准温度之差与养护时间积分,即为成熟度,同时测定试块强度,可得强度一成熟度的关系曲线。由此关系,根据记录的温度一时间。导出成熟度。予测混凝土强度。目前,就室外条件下养护混凝土的成熟度问题,很少进行研究。这一研究的目的在于:(1)估价成熟度值用以予测现场条件下养护的混凝土强度。(2)研究早期温度对强度—成熟度关系的影响。
I. Preface Using the maturity method, the concrete strength can be measured, the best demolition time can be determined, and the temperature of the concrete standard sample can be recorded for a time. The difference between the temperature and the reference temperature and the curing time is the integration, which is the maturity. The intensity of the test block can be obtained as a curve of maturity. From this relationship, according to the recorded temperature for a time. Export maturity. Predict concrete strength. At present, few studies have been conducted on the maturity of concrete under outdoor conditions. The purpose of this study was to: (1) Assess the value of maturity to predict the strength of concrete cured under field conditions. (2) Study the influence of early temperature on the intensity-maturity relationship.
