Effect of Fly Ash-Lime and Rice Husk Ash in Manufacturing of Brick

Abstract

Need for building materials is growing at an alarming rate and in order to meet the demand for new buildings, new ways and techniques must be evolved. The use of alternative materials for bricks should be encouraged in order to preserve precious fertile top soil. In such case thermal power stations use pulverized coal as fuel generates large quantities of fly ash as by-product. India generally called as agricultural country and gives many by products such as rice husk, straws etc. These agricultural wastes can be used in stabilization of soils, as one of its cases can used to improve the properties of bricks. Optimum combinations of fly ash-lime and rice husk ash with clay for manufacturing of bricks have been found from laboratory testing.
