The influence of recycled coarse aggregate contents on the compressive strength of concrete,the strength development with ages,the age factor and the applicability of 28d compressive strength equation of normal concrete were investigated.
主要包括再生粗骨料含量对再生混凝土抗压强度的影响,再生混凝土抗压强度随龄期的发展规律,再生混凝土的龄期系数以及普通混凝土28 d抗压强度方程对再生混凝土的适用性。
