Use of Bagasse Ash Mixed with Quarry Dust and Building Scrap in Brick Making

There is a strong demand in our country for environmentally safe reuse and effective disposal method for sludge due to the increasing amount of sludge generated by the various industries or plant in India. Landfills techniques are commonly used for disposal of sludge in India, rapid urbanization has made it increasingly difficult to use the above techniques. Therefore, incineration process has become one of the few alternatives available for disposal of sludge. The ultimate disposal of incinerated sludge ash can be accomplished by using it as an engineering construction materials. One possible solution for the management of this ash is to re-use it as a building material, namely to incorporate this ash into making of bricks. The fire clay brick is one of the most common and abundant masonry building material. As such, the recycling of waste materials by incorporating them into bricks has been a popular topic of investigation over the last few century, with varying degrees of success across a wide range of waste material. This popularity is likely due to flexibility on the type of wastes which can be mixed into the brick making material, but more importantly, the high temperature involved in firing the bricks allows for the volatilization of dangerous component, as well as the fixation of wastes into the vitreous phase of the brick. The current study investigates the potential for reusing sugarcane industry sludge by using it as a partial replacement material in clay bricks.
