水泥稳定珊瑚礁砂在工程上的应用

根据珊瑚砂的特性,提出了不同含石量的无侧限抗压强度,以混合料中极端含石量的无侧限抗压强度作为优化水泥的含量,介绍了未筛分的珊瑚礁砂的基层配合比的设计及施工过程中的质量控制,实践结果证明,珊瑚礁砂作为基层稳定材料效果较好,取得了良好的社会经济效益。

According to the characteristics of coral sand,the unconfined compressive strength with different rock contents is putforward,and the unconfined compressive strength of the mixture with extreme rock content is taken as the optimization of cementcontent. This paper introduces the design and quality control of the mixture ratio of unscreened coral reef sand in the course of con-struction. The practical results show that the coral reef sand is a good material for stabilizing the base course and has achieved goodsocial and economic benefits.
