Experimental investigation on granite waste and alccofine in concrete

ABSTRACT

Population growth and rapid pace of globalization have increased the demand for construction materials. River sand is one of the main materials used to make the fine aggregate for concrete. As a result, finding an alternative to sand has become crucial. Granite debris and M sand are employed in place of river sand in this experiment. In this experiment, granite debris as well as M sand are used in place for river sand. Concrete constructed using granite waste and alccofine was compared to ordinary concrete that had a 0.50 w/c ratio using the M25 mix design. 10% of alum is added to cement, and 0% to 30% of fine aggregate is replaced with granite waste enrich the physical properties by 23%, 9% and 41% in compressive, split tensile and flexural strength. The mechanical and microstructural characteristics are looked at in this investigation. According to the test results, concrete made with 10% alccofine, 15% granite waste, with 85% M sand performs satisfactorily. In addition, super plasticizers are acceptable in the M5 mix compared to the other mixes. The microscopic images show a densely packed cement matrix and the aggregate transition area, which points to strong bonding.
