摘要
针对实际工程中废弃混凝土种类和原始强度等级,采用不同粗骨料取代率配制再生混凝土,测试其抗压强度.结果显示,在标准配合比下,原始混凝土来源和强度等级对再生混凝土抗压强度有影响,再生粗骨料取代率的影响相对较小.
Based on the types and compression strength of different original concrete and different substitution rate, the compression strength of recycled concrete was obtained. Research has revealed that influences to the recycled concrete of compression strength of original concrete was more than substitution rate.
