Nowadays it is very important to make the concrete economical. Therefore the present work has initiated to make the concrete economical by replacing the natural sand by crushed sand in the concrete. From our study it is concluded that different Crushed sand gives different results for compressive strength depending on different quarries and from study of different research paper at 40% to 50% ...
