摘　　要：在碎砖骨料再生混凝土配合比设计的基础上,设计并完成了192块碎砖骨料再生混凝土立方体试块抗压强度与抗折强度试验,研究表明再生混凝土力学性能与碎砖骨料掺量、粉煤灰掺量有很大关系。并利用回归分析得出,混凝土抗折强度与抗压强度的平方根呈良好的线性关系。Based on the mix proportion design of recycled brick aggregate concrete, experimental work for the compressive strength and flexural strength of recycled brick aggregate concrete was designed and performed with 192 cubes.The results indicated that the recycled brick coarse aggregate replacement ratio and the fly ash content had a remarkable influence on the mechanical properties of recycled aggregate concrete.Using the regression analysis,it showed that concrete flexural strength had a good linear relationship with the square root of the compressive strength.
