Abstract
In this experimental study, granite dust (GD), industrial waste material, is used as a partial replacement of cement in a solid block. Replacement of cement by GD in proportion varying from 0%,5%,10%,20% by weight of cement is done. For each replacement, the compressive strength of the cube after 7, 28, and 60 days is noted. From the compression test conducted, favorable strength is attained at a certain percentage, which has been noted, and by keeping that certain percentage of GD, fine aggregate is partially replaced with manufactured sand (M-sand). Fine aggregate is a significant raw material in construction works that is naturally available. However, due to the over-exposure of river sand, it becomes scarce nowadays. So, an alternative for this is M-sand, which is produced in companies to meet the demand. Replacement of fine aggregate in proportion varying from 0%, 20%, 40%, 60%, 80%, 100% by weight of fine aggregate. For each replacement Workability test such as Slump cone test, compaction factor test, Compressive strength of cube, Compressive strength of concrete block (300mm x 150mm x 200mm), Flexure test, Split tensile strength and Durability tests such as water absorption test, acid test, and the alkaline test is noted after 7,28 and 60 days. From the test result, it is found that the concrete at a level of 10% partial replacement of cement with granite dust and 40% partial replacement of fine aggregate with M-sand gives better workability and high compressive strength.
