摘要
The disposal of olive oil industrial waste is an environmental problem regardless of the manufacturing process. Contamination of soils with wet pomace (a waste product of the two-phase olive oil extraction method) can be a serious problem. Moreover, it cannot be composted or burned without expensive pre-treatment. In this work, we used wet pomace as a pore-forming additive in the manufacture of clay bricks to evaluate the possibility of obtaining a lightweight construction material with good insulating characteristics. To this end, bricks were prepared by adding 5, 10, 15, 20, and 25 wt% wet pomace to the clay without additional water. The results indicate that the incorporation of 10 wt% wet pomace is beneficial for manufacturing good-quality bricks, obtaining an apparent density of 1.43 g/cm(3), a compressive strength of 40.22 MPa, and a thermal conductivity of 0.72 W/mK.
