Hospital waste is being generated from hospitals, clinics & laboratories. Disposal of this waste ash is an environmental concern and it will lead to spreading of diseases. In every country the generation of hospital waste is increasing rapidly. There is scope of utilization of this waste ash in concrete. In this work different parameters of concrete like compressive strength, split tensile strength, flexural strength was studied by partially replacing

1)           Cement with HWA

2)           Cement with HWA & Metakaolin

3)           Fine aggregate with HWA from different authors is presented here.

The study shows that replacement of HWA with cement at 1, 2.5%, 3, 5%, 7.5%,15%&20% increased compressive strength, Split tensile strength &Flexural Strength parameters at 3% & 5% respectively, when cement replaced with HWA and Metakaolin at 5%,10%,15% & 20% shows increase in Compressive strength, Split tensile strength &Flexural strength at 20% and when HWA replaced with fine aggregate at 10% ,20%,30% & 40% strength parameters were reduced. The results were not consistent.
