The aim of this project is to make light weight tile prototype from waste glass under hydrothermal conditions. The waste glass which contains about 67 %wt of SiO2 as starting material was powdered and sieved to particle size under 45 μm. It was blended with commercial grade calcium hydroxide and water. The mixed powder was compacted in a die and cured in saturated steam. Formulation ratio of the glass powder to the calcium hydroxide is preferably between 100:0 - 50:50 with different water contents (5, 10 and 15 wt%). Effects of raw material compositions, water content and compaction pressure on some properties of the porous material were studied. It was found that the optimum composition was 80 wt% glass powder : 20 wt% calcium hydroxide with 5 wt% of water content at the maximum compaction pressure. The tile prototype of 10 x 10 x 0.6 cm. in size has the highest bending strength at 12.21 MPa and the bulk density at 1.80 g/cm3. The tile prototype has been registered under the petty patent no.8030000940 on 1 Aug. 2008.
