In conventional concrete we want to gain more strength with the optimum materials. That's why here we are
using zeolite in concrete for the replacement of cement which might absorbing CO2. Due to rapid change in metrology,
deep minimizing emission will be required in coming decades. Global warming is controlled by the process of reducing
greenhouse gases like CO2, HFC and Sulphur-di-oxide in atmosphere. Zeolite powder is good agent to absorb harmful
gases. Natural zeolites form where volcanic rocks and ash layers react with alkaline groundwater. Zeolites also
crystallize in post-depositional environments over periods ranging from thousands to millions of years in shallow marine
basins. Concrete with zeolite as partial replacement material with mean ratio it absorbs harmful gases and gives high
compressive strength, hence it is eco friendly.
In this project, concrete made with cement is partially replaced with zeolite and then compared with normal
concrete. Here cement in concrete is partially replaced with the zeolite in the respective proportions such as 10%, 20%,
30%, and 40% and the specimens were casted and tested for their mechanical and durability properties.
