The coffee husk is a fibrous material obtained from coffee beans. It is a waste from coffee industries. In order to reduce the disposal problem, utilization of waste materials in civil engineering works is very important. This study has been carried out to explore the utilization of coffee husk ash for improving properties of Kumarakom clay and also to develop brick using CHA and lime by minimizing the amount of clay. Kumarakom clay is known to be very problematic in construction field. It is considered neither suitable for building houses nor for construction of roads. Coffee husk is a by-product of coffee roasting process. After removal of coffee beans, a huge amount of coffee husk is generated later, the ash obtained after burning of coffee husk i.e; Coffee Husk Ash (CHA) is used in this study. Brick is developed using clay – CHA – lime mix and the properties are determined. On comparison with an ordinary brick the properties were found to be satisfactory. In order to reduce the soil scarcity problem, effective utilization of waste materials for the industries can be done for brick development.
