摘要
本文主要研究石粉对混凝土工作性能的影响,通过在0～5mm矿山废石中掺加不同比例的石粉,观察混凝土的工作性能,确定石粉在矿山废石中的有利掺量。试验结果表明,对中低强度混凝土(C30、C40),0～5mm矿山废石石粉含量控制在<15%为宜;对较高强度混凝土(C50、C60),石粉的适宜含量为5%～10%。
The paper studies the impact of stone powder on the workability of the concrete.Through the powder in the 0-5mm chats of adding different proportion,we observed the working performance of concrete,then determined a favorable amount of powder in the chats.Experimental results show that,for low strength concrete(C30,C40) stone powder,the content of 0～5mm chats should be controlled within 15%,high strength concrete(C50,C60),content of stone powder is suitable for 5%～10%.
