| Abstract | ||
| Three different mixtures (sand:clay), (80:20), (70:30) and (60:40), were formed in a cylindrical shape of 50×50 mm, using a semi–dry pressing with 300 kg/cm2 as forming pressure and then fired at 1430˚C. The results showed that the produced semi silica bricks have apparent porosity ranging from 21.3-25% with specific gravity between 2.42-2.93 N/mm2 and having spelling resistance between 15 to 25 cycle. The results show that it is possible to use a mixture of 60:40 sand:clay for the manufacture of semi silica bricks. | ||
