单掺板岩石粉对水泥胶沙抗压和抗折强度的影响
首发时间:2009-04-01
摘要:为了研究石粉以等质量替代水泥后,不同掺量对水泥胶砂力学性能的影响,本文参考GB/T17671-1999《水泥胶砂强度检测方法(ISO法)》测试了掺入板岩石粉后水泥沙胶不同龄期的抗折和抗压强度,然后跟纯水泥胶的相比。实验结果表明石粉的掺入对水泥胶砂的抗折强度影响不大,但其对水泥胶砂早期的抗压强度改善明显。

The effect caused by replaced cement mortar with mono-slate-powder on the flexural and compressive strength
Abstract:When slate powder with the same replacement quantity was added into cement , in order to investigate mechanical properties of the replaced cement mortar , we tested the flexural strength and compressive strength at the different ages ,according to GB/T17671-1999《cement mortar strength detection method(ISO)》. The results indicated the replacement of cement by slate powder had a little effect on the flexural strength. However, it boosted the compressive strength apparently at the early age.
Keywords: slate powder flexural strength compressive strength cement mortar
