During construction, the leftover marble waste used in concrete can be an approach to developing a sustainable alternative for coarse and fine aggregate.

This may help to resolve the problem of shortage of basaltic coarse aggregate and river sand in some parts of the world.

摘要

During construction, the leftover marble waste used in concrete can be an approach to developing a sustainable alternative for coarse and fine aggregate. Waste Marble can be recycled into a useful resource by using it as aggregate in geopolymer concrete. Waste was first separated and then crushed by using a Jaw crusher to get the required diameter of aggregate. Crushed waste was first categorized as coarse and fine aggregate as per IS 383. Basic properties of raw materials like crushing value and impact value are also evaluated prior to making concrete. The slump cone test was used to evaluate the workability of concrete prepared with marble waste aggregate and concrete prepared with basaltic aggregate. Concrete cubes of 150 mm × 150 mm × 150 mm size were cast. Cubes were kept in the oven at 60 degrees Celsius for one day (24 h) then de-molded and cured in the oven for one more day at 60 degrees Celsius followed by further storage at ambient temperature. The test for compressive strength was conducted 3, 7, 14, and 28 days following the casting date. It was discovered that the strength of concrete using marble waste aggregate was comparable with that of concrete with basaltic aggregate. Characterization was done on material as XRF. This may help to resolve the problem of shortage of basaltic coarse aggregate and river sand in some parts of the world. This will also help to recycle the huge quantity of Marble waste which is about 20% of the total production of Marble articles.
