Pcc constituents quantification through partial replacement of fine aggregate and cement

Abstract

The paper aim is to acknowledge the use of Quartz Sand (silica sand) & Metakaolin in replacement of natural sand and cement. As the natural sand is depleting at an alarming rate due to perpetual mining and on other side the emission of co2 from production of cement causing global warming. The M30 grade is prepared as well as evaluated for strength characteristics viz. split tensile, compressive and flexural. Ordinary Portland cement is replaced with metakaolin at 0,10,20,30,40 and 50%, while the fine aggregate is replaced with Quartz sand at 40% constant by weight. The specimens are casted and tested for split tensile, compressive and flexural strengths after curing for 7,14,28 days.
