Abstract:
The objective of this study was to crush fired brick waste, known as grog, which is used in mixtures
with clayey bodies and cement for unfired brick production. The study evaluated the effects of the grog
addition up to 50-90 wt.% and 10 - 50 wt.% cement on the compression forming on the physical and
mechanical properties of clayey bricks after being fired at 900 1000 °C. Unfired clay brick consisting of
70% grog and 30% cement powder had a shrinkage volume of 6.5% and bulk density of 1.9 g/cm2. The unfired
clay brick is resistant to bending at 92 kg/cm2 and has compressive strength at 18 MPa. These physical and
mechanical properties of unfired clay bricks achieved Thai industrial standards' requirements (TIS 77-2545).
The results indicate that adding grog did not impair the compression formation of the unfired clayey body.
Reserves above 15wt% decreased the mechanical strength of the mixing process and the dry body. That is
associated with increased porosity during the drying stage due to the grog behavior.
