摘要

通过外掺法

研究了石粉含量分别为16%、20%、24%时碾压混凝土的拌和物性能、力学性能及耐久性能

并与石粉含量为11.5%的基准碾压混凝土进行了对比。研究结果表明:随着外掺石粉含量的增加

碾压混凝土的VC值相应增加

含气量相应降低

碾压混凝土中的空隙得到填充

其压实密度也相应增大

密实性有所提高;对抗渗性能而言

石粉含量从11.5%增加到16%时

抗渗系数有明显降低

石粉含量超过16%时

抗渗系数基本趋于稳定;石粉含量在16%～20%时

抗压强度值最高

石粉含量大于20%时

随石粉含量的增加

碾压混凝土抗压强度呈下降趋势。

Abstract

By mixed stone powder with 16%

20% and 24% respectively

the influence of different stone powder content on fresh concrete

mechanical property and durability of RCC were studied.The results were compared to that of RCC with 11.5% stone powder.The research showed that value VC increased and air content decreased when the mixed stone powder content went up.Meanwhile

the interstice in RCC can be filled which resulted in higher volume weight and more compact concrete.While the stone content increased

the permeability coefficient went down.When the powder content exceeded 16%

permeability coefficient comes to a constant.The prime range of powder content is between 16%

which leads to the higher compressive strength.While the content exceeded 20%

the compressive strength of RCC decreased with the powder conten

t increasing.
