摘要
以废轮胎橡胶粉作为改性材料,研究了橡胶粉含量和细度对高强混凝土密度、坍落度、抗压强度、劈裂抗拉强度和抗折强度的影响。研究表明:随着橡胶粉掺量的增加,橡胶粉高强混凝土材料的密度、坍落度、强度会下降。橡胶粉的粒径对高强混凝土的抗压强度、抗折强度影响不明显,但劈裂抗拉强度就随着橡胶粉粒径的增大而下降。
The performance of high strength concrete （HSC） modified by recycled rubber powder was tested and analyzed. Effects of rubber contents and size on density, slump, compressive strength, splitting-tensile strength, and flexural strength of high strength concrete were investigated. Test results showed that the increase of rubber content would reduce the density, slump and strength. The size of the rubber particles had little effect on compressive strength and flexural strength, while it had much more effect on splittingtensile strength.
