再生混凝土基本性能的改善方法

Method for improving the basic performance of recycled concrete

综合再生混凝土国内外研究现状,发现再生混凝土与普通混凝土相比,有粘聚性和保水性好,低脆、韧性好的特点,而流动性差,强度稍低,抗冻性差。同时针对再生混凝土劣于普通混凝土的性质,介绍了改善措施及改善效果,总结出再生混凝土在生产过程中的应用是可行的。

Through synthesizing the present research situation of recycled concrete at home and abroad,it was discovered that compared with normal concrete,recycled concrete had not only the characteristics of better cohesion property and water retention property,lower brittlement and better ductility,but also displayed lower fluidity,lower strength and worse anti-freezing property.At the same time,according to the performance of recycled concrete which was inferior to normal concrete,the improving measures and effects were introduced.It was confirmed that the recycled concrete was applicable in production processing.
