研究了橡胶粉掺量对不同强度等级的高强高性能混凝土拌合物含气量与流动性的影响。结果表明：随着橡胶掺量的增加，各强度等级的混凝土拌合物的含气量增加，而坍落度与扩展度减小；橡胶掺量为8％时，橡胶混凝土拌合物的含气量增加幅度较大，坍落度与扩展度损失幅度较小。

The experimental researches the influence of rubber dosage to the air content and liquidity of high strength and high perform-ance concrete which different strength grades. The results show that the air content of flesh concrete increase and the liquidity reduce in-creasing as rubber mixed quantity. Within the range of 8%of rubber mixed quantity,the flesh rubber concrete′s air content increased by a big margin,loss of lesser magnitude of liquidity.
