- W779256130 abstract "Partial and total replacement of fine aggregate in conventional concrete with quarry sand has been empirically conducted with the view too examining primarily the compressive strength of the resulting composite and possible utilization of quarry sand a s fine aggregate in the production of medium grade concrete. The results of the study revealed that it s specific gravity, bulk density, porosity, water absorption, silt content, the impact value and the aggregate crushing value showed satisfactory performance. The percentage replacement of natural river sand with quarry sand for a designed strength of 25N/mm 2 varied at intervals of 10% up to a maximum value o f 100%. A total of 134 cubes of 150◊150◊150mm were cast and tested at 7, 14 and 28 days of hydration. Compressive strength increases with curing age in all the mixes. Compres sive strength decreases with increase in percentage of quarry sand. Generally the compressive strength of concrete incorporating quarry sand attained strength above 23.71 N/mm 2 which makes it a suitable aggregate for the product ion normal weight concrete." @default.
