of the concrete. This project describes the feasibility of using the zeolite in concrete production as partial replacement of cement. Test result show that zeolite is capable of improving mechanical properties of concrete .
Abstract -
An experimental investigation was carried out to study the effect of addition of zeolite powder on the properties of concrete. Cement is replaced by zeolite in different percentages, such as 0%, 5%, 10%, 15%, 20%, 25%, 30% and 35%. The study is done on M30 grade concrete. Currently the CO2 concentration in the environment is getting increased leading to serious climate change and green house effect. Arresting of CO2 from atmosphere ,from point source and reducing atmospheric CO2 concentration can be done by using zeolite powder. Zeolite, a type of natural pozzolanic material, is abundantly deposited in China and is easy to quarry. Natural zeolite is developed naturally in several regions ,where pre-historic volcanic activity has happened near alkaline or salt water. Concrete with zeolite as partial replacement material , absorb harmful gases and gives high compressive strength hence it is eco-friendly.

1.INTRODUCTION
2.1.2 Zeolite powder
Portland cement is the broadly used binding material in construction and maintenance industry because of its sound properties. In construction industry the Carbon di-oxide emissions primarily come from cement production. The cement production plants discharge or release carbon di-oxide approximately 85% of the cement quantity produced or manufactured .Thus they magnify the carbon di-oxide amount in atmosphere and it leads to global warming. Reducing of carbon di-oxide is required in atmosphere, due to rapid and serious climate change. By using Zeolite material in construction industry, it is found that it can absorb carbon di-oxide and reduce the air pollution.
Zeolite is natural volcanic mineral that is mined in certain parts of the world. When volcanoes erupt, molten lava and thick ash pour out. Because many volcanoes are located on an island or near an ocean, this lava and ash often flow in to the sea. The chemical reaction between the ash and the salt water, results in amazing minerals like zeolites.

The material Zeolite is a rock constituted of aluminium, silicon and oxygen. It is developed naturally in several regions ,where pre-historic volcanic activity has happened near alkaline or salt water . Zeolite has a natural porosity because its crystalline structure has windows, cages and super cages. The cages are smallest cell and super cages bigger than cages. The natural zeolite exhibits pozzolanic reactivity which is connected to its metastability and large surface area, and its mineralogical and chemical composition. And as per test results it improves the strength
