The present dissertation is on replacement of fine aggregate, as metakaolin, brick powder & fly ash, in this present construction concrete world the natural resources are undergoes to depletion and wastage of various materials are increased day by day. The construction growth also increased due to the heavy population .in this present manuscript the various materials are used as fine aggregate and check the concrete characteristics at various curing periods and know the behavior of the concrete. In this present study deals with the strength properties of concrete by using flyash,metakaolin& brick powder as partial supplements for fine aggregate at 0,5,10,15,20 at various curing periods 7,28,56 days. The use of materials in cement concrete a) Materials will modify properties of the concrete b) Control the concrete production cost c) To overcome the scarcity of fine aggregate d) clever usage of waste materials
