【摘要】：小型空心砌块(以下简称砌块)已成为建筑空间非承重墙、框架填充墙的主导新型墙材之一。因此,采用陈积粉煤灰和再生混凝土骨料等质量替代部分水泥和机制砂,制备建筑垃圾小型空心砌块,试验结果发现,随着胶凝材料用量的增加,制品的强度和密度也相应提高;当水泥用量达到20%,陈积粉煤灰用量在5%、10%时,砌块强度大于10.0 MPa。试验结果表明,掺加陈积粉煤灰制备强度大于10 MPa的砌块是可行的。
[Abstract]:The small hollow block (hereinafter referred to as the block) has become one of the leading new wall materials for building space non-load-bearing wall and frame-filled wall.Therefore, using quality such as aged fly ash and recycled concrete aggregate instead of some cement and machine-made sand, the small hollow block of construction waste is prepared. The experimental results show that, with the increase of the amount of cementing material,The strength and density of the products also increased correspondingly, and when the cement content reached 20, the amount of fly ash aged was 5 and 10, the strength of the block was more than 10.0 MPa.The experimental results show that it is feasible to prepare blocks with strength more than 10 MPa by adding aged fly ash.
