Concrete is the most used in day to day life in building and road material in world also nowadays pollution is also increasedinsurroundingsoourprojectworkistotrytosolvethisproblembypreparingconcretewhichabsorbingcarbondioxide zeolite is used to prepare this type of specimen.
Zeolite has properties to absorb natural gases and, in this project, we try to replace cement with zeolite with specific percentage of replacement.
Introduction
Summary:
With rising population, construction demand increases, leading to higher cement production and carbon dioxide (CO?) emissions, which harm the environment. Vehicle emissions further worsen pollution. To reduce CO? emissions in road construction, this study explores using zeolite powder—a porous material with high surface area—as a partial replacement for cement in concrete to enhance CO? absorption.
Objectives:
Analyze physical and chemical properties of zeolite and cement.
Determine the optimal zeolite replacement percentage for maximum concrete strength.
Compare the cost-effectiveness of conventional concrete and zeolite-added concrete.
Properties of Zeolite:
Environmental benefits include CO? absorption and water filtration.
Chemically stable with strong durability and hydrophobic characteristics.
When mixed with concrete, zeolite reduces permeability, enhancing durability and lifespan by protecting against water and chemical damage.
Concrete Preparation:
Concrete blocks were prepared using standard procedures and mix proportions from M30 grade concrete, with 20% and 30% cement replaced by zeolite powder.
Testing and Results:
Compressive strength tests showed that concrete with 20% and 30% zeolite replacement has comparable or slightly improved strength compared to conventional concrete.
Carbonation tests demonstrated that zeolite concrete also helps in CO? capture with around 10-13% carbonation area observed.
Comparison:
Zeolite concrete exhibited improved strength after curing compared to conventional concrete, proving it a viable, eco-friendly alternative for construction materials with added environmental benefits.
Conclusion
Concreteabsorbscarbondioxide(CO2)throughanaturalprocesscalledascarbonation. Thisprocesscanoccurthroughoutthelifeofconcretestructure.zeoliteaddedconcretehasmorestrengththanconventionalconcrete. When we add 20% zeolite, we come to know that strength is more as compare to 30% of replacement ofzeolite. Zeolite added concrete absorbs more CO2 as compare to conventional concrete. Cost of zeolite added concrete is 10% more than conventional concrete)”.
