This research is to investigate the properties of compressed building bricks producedfrom Cameron Highlands reservoir sediment. The particle size distribution of the sediments are graded as silt and sand. The sediments used were as total replacement of the normal soils used in the compressed soil bricks. This paper presents the compilation of experimental brick properties; compressive strength, water absorption, microstructure and heavy metal leachingof the compressed sediment bricks. The experimental results shows that increasing use of reservoir sediments decrease the compressive strength andincrease the water absorption. The heavy metal concentrations of the leachates from the leaching test are all within the regulatory limits. The optimum mix is derives from the compressive strength and the water absorption in which in this research is Mix 4, 70% sedimenta, 20% sedimentb and 10% cement,complying with ASTM C129 – Non Load Bearing Bricks [1].

The objective of this research is to investigate the potential use of Cameron Highland reservoir sediment in compressed brick production. The sediments can be classified as well-graded clayey sandy SILT and well-graded gravely SAND whereby the grain size is comparable to the grain size of sand and silt. The sediment was used as a 100 % replacement for the soils content in conventional soil cement bricks. Besides that, sodium bentonite, mica, fly ash and bottom ash are used as pozzolan to partially replace the cement in the sediment cement bricks. This paper presents the compressive strength of sediment cement brick incorporating sodium bentonite, mica, bottom ash and fly ash as partial replacement of cement. The total replacement of soils by Cameron Highland reservoir sediment (Mix 2) shows significant increase in compressive strength of the bricks compare to the conventional soil cement bricks (Mix 1), while partial replacement of 10 % pozzolan results in optimum strength. On the other hand, 10 % of bottom ash and 10 % of fly ash (Mix 13) as partial replacement of cement achieved the highest compressive strength. This implies that sodium bentonite, mica, fly ash and bottom ash can be used as pozzolan to partial replace the cement.
