In the present experimental study natural sand is completely replaced by manufactured sand and cement is replaced by marble dust at (5%, 10%, 15%, 20%) varying percentages. Marble dust is the by-product and waste produced after cutting the stones in industries which is the sludge form. Marble dust has pozzolonic properties therefore it can be replaced to cement. Due to constant sand mining, there is a shortage of natural river sand and more mining can lead to several environmental problems and therefore, it is necessary to find alternative to the river sand. M-sand has been introduced as a replacement to the river sand, which is a controlled end product and free from organic matter. Test on fresh and hardened properties of concrete was conducted. Superplasticizer was added to have good workability. The concrete with 10% MD and 100% M sand gave maximum compressive, split tensile and flexural strength. In the durability test, it is observed that the rate of water absorption increases as the substitution percentage in concrete mixes increases. The mix design was carried out for M40 grade concrete as per IS: 10262-2009.
