FEASIBILITY STUDY OF BRICKS FROM MARINE CLAY

Abstract

Covering a quarter of the Singapore Island, excavated marine clay, the main constituent of the Kallang Formation, was disposed to designated areas such as the Changi Staging Ground (CSG). These materials are then barged and reused as infill materials for the reclamation projects in Singapore. Providing as an alternative recycling solution, this research investigates the feasibility of the production of building bricks using Singapore marine clay together with varying sand composition. The experiment was conducted within a temperature range of 1020 -1033oC with sand composition varying from 0- 40% .The experimental results indicate that all the varieties of clay brick specimens with various percentages of sand additions met the requirements for building brick as stated in Singapore Standard 103:1974 Specifications for burnt clay and shale bricks. This means that the Singapore marine clay can be used as an alternative replacement for producing building bricks, hence better utilizing the excavated marine clay.
