再生混凝土抗压强度试验研究

摘要

通过对实验室及室外等3种不同的废弃混凝土再生后进行抗压强度试验,研究了取代率分别为0,40％,70％,100％的再生粗骨料混凝土及再生细骨料混凝土抗压强度.研究结果表明,再生混凝土的取代率对再生混凝土的抗压强度影响很大.室内与室外骨料再生混凝土的抗压强度变化规律不同.针对实验提出了再生混凝土抗压强度与取代率关系的公式.%We studied compressive strength of recycled aggregate concrete with 0, 40% , 70% and 100% replacement rates. The results indicated that the recycled aggregate concrete replacement rate has a remarkable influence on the compressive strength of recycled aggregate concrete. According to the ex-periment, formula of the relationship between recycled aggregate replacement rate and compressive strength of recycled aggregate concrete is present.
