Abstract – Concrete manufacturing involves additional cementitious material which results in increase in the production of carbon dioxide gases which results in the damage of the most of layer of earth. The replacement of cement with GGBS in the various percentage. The tests such as compressive were done in Cubes, cylinder and beam. Ground Granulated Blast furnace Slag can recover the stability characteristic of concrete compared to control mix. In the project cement is replaced 0%,10%,20%,30%,40% and 50% of Ground Granulated Blast furnace Slag replaced. The strength of concrete seems to be increased when we replace cement with 30% of GGBS. Beyond that the strength seems decrease.
Keywords – Ground Granulated Blast Furnace Slag, Compressive strength, Flexural strength, Durability, Cement
Concrete is the largest the widely used construction materials. Concrete is usually connected with Portland cement because OPC is the most important element for production of concrete. The claim for concrete as a building substance is onthe argument. In accumulation, the scope of power required to create OPC is only next to steel and aluminum. Slag improves with respect to strength and durability.
Collection of materials
Initial test on materials
Mixing of materials
Filling the cubes
Test on cubes
Making the concrete cubes by partially replacing the cement with GGBS in M25 grade.
Cube samples are prepared in the way different trial GGBS: 5%,10%, 20% ,30%,40% and 50% Replacement for GGBS.
Ground granulated blast-furnace slag
Ground granulated blast-furnace slag GGBFS, is a by- product of iron in blast-furnace. It mainly consists of silicate and aluminosilicate of melted calcium that is periodically be removed from the blast furnace.

Design of Concrete Mix
Mix has been calculate on Indian standard recommended guidelines IS 10262 2009. From the mix design, quantity of cement, fine aggregate and water cement ratio are calculated.

RESULTS AND DISCUSSIONS
AVERAGE VALUE OF COMPRESSIVE STRENGTHON CUBES
The average compression strength of cubes are tested and expressed in the table 6 below:
Table 6: Average Compressive Strength on Cubes
Figure 3: 0% of compression test results
Figure 4: 5% of compression test results
Figure 5: 10% of compression test results
Figure 6: 20% of compression test results
Figure 7: 30% of compression test results
Figure 8: 40% of compression test results
Figure 9: 50% of compression test results
Finally, after the replacement of GGBS as 60% and more, there should be no more increasing its strength. Comparing all these 30% replacement having proven valuable strength.
On replacing cement with GGBS, the maximum compressive strength is obtained in 30% replacement and the value obtained is 28.52N/mm2 at 28 days curing.
Thus, GGBS can be used as a substitute for cement.
This replacement of GGBS in the cement reduces the emission of carbon dioxide gases thus helping in giving an ecofriendly environment.
