Abstract

The aim of this study was to introduce 5% up to 40% of low grade silicon carbide (LGSC), with construction excavated soil before the soil being reused as raw material in Eco brickmaking. Furthermore, stone sludge was added to mix with LGSC to fabricate eco bricks. The results indicated that the use of 10% granite sludge, 30% LGSC and 5% brick waste clinkers could produce grade-2 eco bricks in sintering temperature 1,050°c, however 30% granite sludge was substituted to obtain the same grade eco bricks. Water absorption of eco bricks has increased during the addition ratio of LGSC increased. However, the compressive strength increased while water absorption decreased during the operation temperature increased from 1,020°c. to 1,050°c.
