Compressive Strength and Workability of Concrete Using Stone Dust as Partial Replacement of Sand and Glass Powder as Cement
International Journal for Research in Applied Science and Engineering Technology
The main objective of this research is to investigated the use of Glass Powder and other is Stone dust as partial replacement of cement and concrete production. In this research we analyze the strength of concrete made with using these waste materials one is Glass Powder and other is Stone dust. The Glass Powder is used as 20% replace by weight of cement and Stone Dust as the partial replacement of Fine Aggregate from 0%, 10%, 20%, 30% and 40%. The grade of the concrete here is M-25 and M-30
... is M-25 and M-30 grade. It has been used as a replacement of fine aggregates in many literature works but this paper presents the feasibility of the substitution of marble waste for cement to achieve economy and environment saving. Slump Test was carried out for the fresh concrete whereas Compressive Strength, Flexure Strength and Split Tensile Tests were carried for the Hardened concrete. All tests are done at 7-day, 14 -day, 28 -day, and 56 days with 0 to 40% replacement of sand at an interval of 10%. Again above tests are carried out with 20% replacement of cement by glass powder. It is observed that the glass powder improve the strength and stone dust can be used as sand. Experiment such as specific gravity test of stone dust and sand by pycnometer method, moisture content of sand and stone dust by oven drying method, normal consistency of cement, and initial setting time of cement, were performed to determine the physical property of concrete. On fresh concrete slump test was preformed to check workability of concrete and after then compressive strength was checked. Thus stone dust is appropriate substitute of fine aggregates in concrete mix for construction. This is great saving in costly material.
