摘要
文章分析了人工砂中不同石粉含量对水工混凝土中新拌混凝土的影响(包括坍落度、含气量),以及对抗压强度、抗冻性和抗渗性的影响。通过各项试验表明,人工砂中随着石粉含量的增加,混凝土的含气量、坍落度不断减小;当人工砂的石粉含量为16%时,硬化混凝土的抗压强度、抗冻性、抗渗性达到最佳效果。
The paper analyzes influence of different stone powder contents on slump and the gas content in fresh mixed concrete,compressive strength,frost resistance and impermeability of the hydraulic concrete.The tests show that with increasing stone powder content in artificial sand,the slump and the gas content of concrete were decreased.The compressive strength,frost resistance and impermeability of the hardening concrete could get the best perforamnce when the stone powder conctent in artificial sand is 16%.
