Abstract
In order to optimize the mechanical properties of cement-lime-phosphogypsum solidified red mud base material,this study analyzed the compressive strength,splitting strength and resilience modulus of solidified red mud base material under different cement,lime and phosph-ogypsum contents and curing ages through laboratory tests.The results show that the compressive strength increases with the increase of cement content and curing age.With the increase of lime content and phosphogypsum content,the compressive strength,splitting strength and com-pressive resilience modulus increase first and then decrease.The road performance of cement-lime-phosphogypsum solidified red mud base material is the best when the content of cement,lime and phosphogypsum is 8%,2%and 5%,respectively.关键词
