Abstract
Fired clay bio-bricks were prepared by adding eggshell as a bio-filler and
flux into earthenware clay compounds via an extrusion process. In this
study, the suiTab. conditions for clay bricks preparation were firing at
1000?C for a period of 5 h. Adding 20 wt% eggshell powder into the clay
brick yielded good physical-mechanical-thermal properties: high compressive
strength and hardness, low thermal expansion coefficient, and low water
absorption. The measured compressive strength, hardness, and refractory
water absorption were 7.0 MPa, 6.0 HV, and less than 15 wt%, respectively.
The obtained clay brick with the eggshell powder added as shown here is
potential for uses as bricks for construction and thermal insulation.
