摘要
研究了用废砖粉作为矿物掺合料对混凝土力学性能、收缩性能及抗冻性的影响。试验结果表明废砖粉的掺入会使混凝土的抗压强度和抗折强度降低;但能小幅的补偿收缩,并且随着其掺量的增加,混凝土收缩减小的幅度也增大;掺入废砖粉对抗冻性有改善作用,掺量在30%时改善作用最明显。
This paper studies the effect of waste brick powder as mineral admixture on mechanical properties,shrinkage and frost resistance of concrete.The results show that the waste brick powder decreases the compressive strength and flexural strength of concrete,but it slightly compensates the shrinkage of concrete,and with the increase of dosage of these materials,the drop amplitude of concrete shrinkage rate increases too.Waste brick powder improves the frost resistance,and the effect is most obvious when the dosage is30%.
