Abstract:
alternative to natural sand. The Granite fines use up to 10%, 20%, 30%,40% and 50% as a partial replacement.
The present study was carried out for 1:3 ratio of cement mortar replacing cement by fly ash at constant percentage of 25% and granite fines replaced by fine aggregate varying percentages of 0%, 10%, 20%, 30%, 40%, and 50%. The results concludes that the maximum compressive strength was obtained 10 % of granite fine and after 10% of granite fines goes on reduced.
1.1 OBJECTIVES OF THE STUDY In this present study the granite fine is using as an alternative material for sand and fly ash is using as alternatives for Cement in cement mortar ratio of 1:3. 1.
1.INTRODUCTION Cement mortar is a building compound created by mixing sand and a selection of aggregates with a specified amount of water. The mortar can be used for a number of applications, such as plastering over bricks or other forms of masonry. The huge demand for mortar and concrete has made this natural resource to get impoverished hence massive quantities of cement needs to be annually produced This production leads to pollute the environment by releasing significant quantities of CO2 emission and on the other hand extraction of river sand in excess has conspicuous environmental impacts. Large quantity of like fly ash, and many other types of ashes and powder form materials is being produced every day leading to many environmental problems. Lot of research has been carried out to use alternative material in cement mortar and concrete so as to satisfy various properties. Granite fine powder is one such alternative material which can be effectively used to replacement for cement and manufacture sand.

Fine aggregate is the most popular building material in the world. Construction Industry contributes huge amounts to Indian economy and Fine aggregate is one of the best materials used in construction. The ingredients used in it include Cement, Sand, Gravel and Water. Now-a-days sand is not easily available. The worldwide consumption of sand as fine aggregate in concrete production is very high, and several developing countries have encountered some strain in the supply of natural sand in order to meet the increasing needs of infrastructural development in recent years. A situation that is responsible for increase in the price of sand, and the cost of concrete. Expensive and scarcity of river sand which is one of the constituent materials used in the production. The use of Crushed Granite Fine (CGF) as an

The following objectives of the proposed work are The main object is to find a suitable and economical alternative for sand in cement mortar with require strength. To study the physical properties of materials such as specific gravity, fineness, initial setting and final setting time of cement etc. To study the Compressive strength behaviour of cement mortar with and without alternative material.
