摘　　要：为探究废弃轮胎胶粒对钢渣混凝土体积变形的影响,在钢渣混凝土中加入胶粒部分取代细骨料,进行混凝土的强度、早期开裂和体积变形试验研究。试验结果表明:加入胶粒降低了钢渣混凝土的抗压强度,且随其用量的增加强度下降越明显;轮胎胶粒等体积部分代替砂后,混凝土的早期塑性开裂得到了一定的改善,改善效果随胶粒加入量而异。综合比较发现10%的胶粒加入量对钢渣混凝土的性能改善效果最为理想。The compressive strength, early-age plastic cracking and volume deformation of concrete were tested to investigate the influence of scrap tire particles on volume deformation of steel slag concrete when substituting partial fine aggregates. The results show that the compressive strength of steel slag concrete containing scrap tire particles steel slag concrete by partiall decrease with the usage increase of scarp tire particles. The expansion of y substitution of fine steel slag aggregate with scrap tire particles shows obvious improvement and the scrap tire particles modified the early-age plastic cracking of steel slag concrete. Comprehensive comparison shows that the 10% scrap tire particles addition modify steel slag concrete with satisfactory effect of the above performances.
