Thamarachal Lake located at Puliyoor, Chengannur, Kerala, is a waterbody of high strategic importance in the Chengannur municipality. As part of the rejuvenation of the lake, an estimated quantity of 43,200 m3 of silt was proposed to be dredged in order to enhance the water storage capacity of the lake. This study focuses on utilizing the dredged material to be used as a potential construction material instead of merely storing it in waste dumps. The geotechnical properties of the Thamarachal clay were tested and compared with clay from a factory which is generally used in brick making. It was found that the basic properties were comparable with the clay used in brick factories. Further, different sets of bricks were cast in moulds and subjected to unfired and fired conditions of drying. Unfired Thamarachal clay bricks were of less strength than standard unfired factory bricks but since it is in the standard range of 2 N/mm2 and 3 N/mm2 it is considerably okay. Fired Thamarachal clay bricks showed less strength and were broken. Thus, the inclusion of other available substitutes for further enhancement of these bricks made of Thamarachal clay was considered. By mixing 60% of Thamarachal clay with 40% of an admixture clay, which enhances the binding properties it was observed that there is improvement in properties in terms of compressive strength and water absorption. From the results obtained by conducting various tests on bricks made of Thamarachal clay and mixed clay (Thamarachal and admixture clay) respectively, the strength is observed to be higher for the latter set of bricks which can thus be manufactured for commercial purposes.
