mechanical and durability characteristics of marble-powder-based high-strength concrete

Concrete is a construction material consisting of cementitious material, fine aggregate, coarse aggregate and water. now-a-days, the cost of these materials is increasing. we need to look at a way to reduce the cost of building materials especially cement. one of the recent advancement in construction industry is the replacement of cement with waste materials in concrete. this replacement offers cost reduction, energy savings and protection of environment. to achieve the above objective, an attempt has been made to replace cement with waste marble powder (wmp) produced from marble industries. the present investigation aims to study the mechanical and durability properties of high strength concrete (hsc) with cement partially replaced by waste marble powder. cement has been replaced with marble powder at 0%, 5%, 10%, 15% and 20%   in this study. the properties of concrete such as compressive strength, modulus of elasticity and flexural strength were determined. the durability characteristics such as water absorption, acid resistance and rapid chloride permeability were also determined.
