The Key Technology Study Of Clay Stabilized In ECO-material Way

It is a high technology of clay stabilized in eco-material way that was focused in Civil Engineering recently. The high technology can be used wildly in various researches and can be used in engineering construction easily, furthermore the cost of it is very low. Thus the technology is very needed in some present projects such as roadbed in highway and foundation strengthen in civil engineering. This experimental research bases on conventional ways which used cement or lime stabilizing clay. At the same time, the experiment used largely industrial wastes such as fly-ash and slag presents such a best optimizing proportioning that can be used sufficiently in roadbed projects and foundation strengthen projects.This paper presents the experimental results on unconfined compressive strength (UCS) and limit of water and plastic (WL, WP) of the clays stabilized with industrial wastes such as fly-ash and slag. Four kinds of the compound clays are produced with different proportions of fly ash, clay, and slag, and then the compound clays are reinforced by adding cement and lime respectively. Based on Geo-technical Engineering and Materials Engineering and using the modern testing technology, this paper analyses the mechanism of the strengthen soils. The experimental results from the laboratory tests show that the compound clays can be better reinforced by using cement instead of lime. The relationship among UCS, curing time and cement content has been verified by using the laboratory test results in this study. The high technology uses industrial wasters and improves environment as well as stabilize soil. It can improve the UCS of the compound clays by adding fly-ash and slag largely, can be beneficial for environmental protecting and cost reducing contemporarily.
