Abstract

The present report investigate the use of crusher dust and floor slab chips in concrete as an alternative fine aggregate and coarse aggregate respectively, the investigations include tests on standard concrete cubes (150 mm x 150 mm x 150 mm), cylinders (150 mm x 300 mm), beams (10 0mm x 100 mm x 500 mm) and short columns (150 mm x 150 mm x700 mm). Tests on the physical properties of crusher dust, floor slab chips and its influence on the strength of fresh concrete and hardened concrete, additionally a comparative study has been done. The properties investigated were fineness modulus, specific gravity, and surface moisture on materials, bulk density, and water absorption. Tests were conducted on 6 cubes, 6 cylinders, 6 beams and 8 short columns for M20 grade design mix with sand and crusher dust as fine aggregates, granite metal and floor slab chips as coarse aggregates. The strength parameters cube compressive strength, Split tensile strength; flexural strength on prisms and compressive strength for short column were compared at 7 days and also at 28 days. Concrete mix design procedure in according to the IS 10262-2009, IS 456-2000 and using 20mm metal was adopted for investigation. The investigation indicates that crushed stone dust is available abundantly as fine aggregate in concrete. The crusher dust not only reduces the cost of concrete and also reduces the effect on environment by taking them in to concrete as an alternative material.
