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 compressive strength of cube after 7, 28 and 60 days is noted. From the compression test conducted favourable 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 which is naturally available. But 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 test such as water absortion test, acid test and 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 a granite dust and 40% partial replacement of fine aggregate with M-sand gives better workability and high compressive strength.
