固废掺量对再生混凝土的性能影响

Influence of Solid Waste Content on Performance of Recycled Concrete

文中以绿色再生建筑材料—废弃玻璃砂和废轮胎橡胶颗粒取代混凝土中的轻骨料,研究了置换量对混凝土性能的影响。研究结果表明,随着再生绿色建筑材料替代量的增加,混凝土的坍落度增加,凝结时间延长,泌水率提高,抗压强度降低,超声脉冲速度降低。

In this paper, green recycled building materials waste glass sand and waste tire rubber particles are used to replace lightweight aggregate in concrete, and the effect of replacement amount on the performance of concrete is studied. The results show that with the increase of the replacement amount of recycled green building materials, the slump of concrete increases, the setting time extends, the bleeding rate increases, the compressive strength decreases, and the ultrasonic pulse speed decreases.
