Cement in concrete has several disadvantages when used without any replacement to it in concrete such as high carbon footprint, high cost of construction, and low tensile strength. To address these disadvantages alternative materials such as fly ash, GGBS, and silica fume can be used, designing concrete mixtures with lower cement content can reduce the carbon footprint, cost, and potential cracking, resulting in more sustainable, cost effective, and durable concrete structures. In our project we are going to use GGBS as a replacement material to cement in varying percentage. GGBS stands for Ground Granulated Blast Furnace Slag. It is a byproduct of the iron and steel industry, produced during the process of iron production in blast furnaces. GGBS has cementitious properties and can partially replace cement in concrete mixtures. It improves the durability, workability, and long-term strength of concrete. GGBS also has a lower carbon footprint than traditional cement, making it an environmentally friendly alternative. It is commonly used in large-scale construction projects such as bridges, highways, and high-rise buildings. This experimental investigation is being conducted to compare the compressive strength of concrete mix of M30 grade with partial replacement of cement with varying percentage of GGBS of 10%,20% and 30% to the dry weight of cement in the mix and find out the optimum percentage at which the concrete mix has highest strength. We are going to test compressive strength of 36 cubes of concrete mix consisting of 9 cubes of nominal M30 mix and 9 cubes of each mix containing 10%,20% and 30% GGBS replaced mix at 7th,14th and 28th day from the day of cube casted.
