UNCONFINED COMPRESSIVE STRENGTH OF MIXTURE OF PHOSPHOGYPSUM-FLY ASH-LIME-CLAY

摘要：

In this paper, the unconfined compressive strength test of mixture of phosphogypsum-fly ash-lime-clay for 7days and 28days curing period is based on 16 kinds of mix design method for orthogonal analysis, the optimum mix of phosphogypsum-fly ash-lime-clay is obtained by the unconfined compressive strength test at the same time. Combined with practice, the application of phosphogypsum to the subgrade and pavement is studied for its feasibility and practicality, and the result shows that phosphogypsum is not only a kind of the best roadbed filler but also a type of the road base course with the excellent performance.
