Application of Spent Bleaching Clay for Producing Environmental Brick

Abstract:

Spent bleaching clay(SBC) is a kind of discarded by-products from edible vegetable oil factory, often resulting in environment pollution. This study aimed to explore a feasible approach to comprehensively utilize the SBC for replacing coal ash to produce unburned and environmental brick(UEB). Through a series of experiments, and considering the cost and acceptability of bricks, the optimal conditions for producing UEB was obtained. The defatted SBC is added 25 %, fine fine sand 25 %, small pebble 30 %, cement 12 %, lime 8 %, the molding pressure is 20 MPa, and the molding moisture was 10 %. Under this condition, the average compressive strength of the UEB with 28-day storage can reach up to 18.11 MPa, higher than the value of 15 MPa in the unburned brick produced from standard coal ash.
