Experimental Study On Absorption Of CO2 By M30 Concrete As A Partial Replacement Of Cement By 25% Of Zeolite

ABSTRACT An experimental investigation was carried out to evaluate the mechanical and durability properties of concrete mixtures containing natural zeolite (NZ) in binary blended system up to 25% replacements. In order to serious climate change, deep reduction in CO2 emission will be required in coming decades.CO2 absorption is one of the key technology to control the global warming. Global warming is caused by sharply increased greenhouse gases emission by human activities. In building industry, CO2 emission mainly come from cement production. Capturing of CO2 from point source, from ambient air and reducing atmospheric CO2 concentration by using Zeolite powder and Zeolite sand. Concrete with Zeolite as a supplement material can absorb large quantity of CO2.Introducing Zeolite material into the concrete absorbs CO2 from the atmosphere hence it will be eco-friendly. Absorb CO2 and reduces the air pollution, Keep environment clean and full of oxygen. Zeolite, a type of natural pozzolanic material, is abundantly deposited in China and is easy to quarry. It is widely used in producing blended cement and concrete structural elements. The direct partial replacement of cement by zeolite resulted in the decrease of compressive strength, especially the early strength and tensile splitting strength. Sillica fume was incorporated to enhance the strength performance of zeolite. It was found that the ternary blended cement (zeolite plus silica fume and cement) concrete performed better than the binary biended cement (zeolite and cement) concrete. Study of effect of zeolite on the strength of concrete made in this study by Choosing M30 Grade of Concrete and Replacement of Cement With 25% of zeolite and Also Project Conducted Compressive Test, Split Tensile Test and Acid Attack Test.
