再生混凝土立方体抗压强度推算公式研究

Study on cubic compressive strength calculation of recycled aggregate concrete

利用试验过程中积累的大量再生混凝土立方体抗压强度数据验证传统普通混凝土强度推算公式,发现对再生混凝土强度推算的适用性较差,采用回归分析得出再生混凝土强度推算新公式,并通过调整有关参数和验证提出了较合理实用的再生混凝土强度推算公式。

According to examining a large mount of experimental data,these traditional cubic compressive strength calculation formulas of common concrete have poor applicability to recycled aggregate concrete.This paper worked out new recycled aggregate concrete cubic compressive strength calculation formulas with regressive analysis,adjusted the coeffi cients and parameters for more applicable formulas of recycled aggregate concrete cubic compressive strength calculation.
