To Study the Strength Characteristics of Concrete Using Waste Marble Powder and Recycled Coarse Aggregates

The objective of the study is to investigate the mechanical properties of concrete with different replacement levels of ordinary Portland cement by Waste marble powder and natural coarse aggregates with recycled coarse aggregates. The standard cubes (150mmX150mmX150mm) were casted. Laboratory experimentation was carried out to analyze the performance of M25 grade mix cases were casted and tested. The strength effect of concrete of various amount of replacement of cement viz. , 5 %, 10 %, 15 % with Waste marble powder and various amount of replacement of natural coarse aggregates with 15 %, 30 % and 45 % with Recycled coarse aggregates. The resultant concrete was tested for parameters like compressive strength, slump and workability and compared with conventional concrete.
