Investigation of few Durability Parameters of Phospogypsum Concrete
Modern concrete is now common to use admixture (chemical or mineral), pozzolana’s for modifying different properties of concrete in fresh and hardened state. This paper presents the salient features of the development of Phosphogypsum(PG) Cement Concrete and discuss the improvements affected in the properties of concrete with the use of PG as an admixture compared to the plain or conventional cement concrete. This was accomplished by an experimental study by preparing different grades of cement concrete mix M20, M25 and M30 using PG as an admixture by replacing 5% of OPC and few durability parameters were investigated. This includes studying the compressive strength, workability, air entrainment and moisture movement by wetting and drying method. Study were conducted for modifying the properties of the concrete, controlling the concrete production cost, to overcome the scarcity of cement, and finally the advantageous disposal of industrial wastes.
