Green Concrete using Waste Materials

Concrete which is made from concrete wastes that are eco-friendly are called as “Green concrete�. Green Concrete is a term given to a concrete that has had extra steps taken in the mix design and placement to insure a sustainable structure and a long life cycle with a low maintenance surface. The objective of this project is to make green concrete with the use of waste materials such as fly ash, artificial manufactured sand, Brick powder and FOSROC CONPLAST SP 430 DIS. Both compression strength and tensile strength are carried on concrete blocks. The conventional concrete, for replacement of cement instead of partial cement 80% fly ash 20%, for replacement of cement instead of partial cement 85%, fly ash 15% added concrete slump values are 92mm, 89.5mm, and 87mm respectively. The density of conventional concrete, For replacement of cement instead of partial cement 80% fly ash 20%, For replacement of cement instead of partial cement 85%. Fly ash 15% added to concrete 2222.22kg/m3,1866.66kg/m3 and 1911.11kg/m3 results are respectively. The 7,14 and 28 days compressive strength test results gives the low compressive strength of the green concrete compare to conventional concrete. Overall results have seen compressive strength, tensile strength and density of concrete considerable low.
