1 EXPERIMENTAL INVESTIGATION ON CONCRETE BY USING HEMP FIBERS AND COMBINED REPLACEMENT OF CEMENT WITH GGBS AND MARBLE POWDER-REVIEW , GADDAM KRISHNA, N. RAVI KUMAR, Dr.K. CHANDRAMOUI
Cement which is the most utilized material after water in present world have some environmental effects. In order to eradicate this we are going to reduce the use of CO2 emitting materials like cement. Keeping this in mind we are going to replace cement with the help of GGBS and Marble powder combinely at 5%, 10%, 15% and 20% to the weight of cement along with the addition of HEMP fibers for M50 grade of concrete. GGBS is the bi-product which comes from iron industry and Marble powder is the wastage that produced from marble stone cuttings. Hemp fiber is the naturally occurring fibre which reduces the tensile cracks of concrete. We are going to test the same for 7 days and 28 days of curing.
