STUDY ON PAVEMENT GRADE CONCRETE WITH PARTIAL REPLACEMENT OF CEMENT BY MARBLE DUST AND M SAND AS FINE AGGREGATE
This paper presents the strength (characteristic) properties of the concrete with partial replacement of cement by Marble dust and using M Sand (quarry dust) as fine aggregate instead of natural river sand for M 40 grade rigid pavement concrete. Uses of waste materials in construction industry have two benefits: one is it substitutes the nonrenewable resources and other isthe best utilization of the waste material and reduces problems of dumping, it also makes the concrete as Eco Friendly as well as Economical one. The river sand is 100% replaced with M sand, and the cement replacement is in different proportion that is 5% 10% 15% 20% by weight of cement with waste material Marble Dust powder. Properties of concrete are tested for fresh concrete and hardened concrete. For fresh concrete slump cone test is conducted and for hardened concrete compressive strength, Tensile strength and flexural strength test conducted after desired days of proper curing. The Design mix is done for M 40 grade pavement concrete 1:2.3:3.02 is the adopted mix ratio. The results of desired concrete are compared with non marble dust used concrete that is conventional concrete with 0% marble dust.
