Study on the Basecourse of Lime-fly Ash Stabilizing Phosphorous Slag Modified by Phosphogypsum

ZHOU Ming kai 1,ZHA Jin 1,SHEN Wei guo 2 (1.School of Materials Science and Engineering, Wuhan University of Technology,Wuhan 430070,China; 2.Key Laboratory for Silicate Materials Science and Engineering of Ministry of Education, Wuhan University of Technology,Wuhan 430070,China)  
When phosphorous slag is used as the aggregate in base course, it is not suitable to be stabilized with cement or lime. However, the mixture of lime fly ash stabilizing phosphorous slag has high strength, which can be used as the base of expressway. With about 6% phosphogypsum, the strength of lime fly ash stabilizing phosphorous slag can be improved. The SEM defect that there had some reaction product on the surface of the phosphorous slag. It would benefit the strength of forming the road base material.
