成熟度早期预测混凝土强度分析

Analysis of Early Predicting Concrete Strength by Maturity

以新成熟度理论为基础,结合试验数据,绘制了标养条件下和夏季同条件养护下混凝土成熟度与龄期的关系图。将公式预测混凝土28d强度和混凝土28d抗压强度实测值进行对比分析,给出了较准确预测混凝土28d强度的龄期天数,为早期预测混凝土强度及施工中模板拆除提供理论依据。

Based on the new maturity theory, combined with the test data, the diagrams of concrete maturity and ages under the standard curing conditions and summer curing conditions are drawn. Through analyzing forecasted concrete strength of 28 days by formula and measured concrete compressive strength of 28 days, the ages that can accurately predict concrete strength of 28 days are gave, which can provide theory basis for the early prediction of concrete strength and the formwork dismantling.
