This study exploited the use of waste soda lime silica glass as an alternate material for making paving tiles. Compositions containing at least 90% recycled glass from 106 microns and minus 75 microns soda lime silica glass powder were prepared. Water, sodium silicate and bentonite were added as the binders and three sets of compacts were made. The first containing water, the second containing sodium silicate and the third set containing bentonite and these were pressed using the uniaxial press method at 5,000 psi and 10,000 psi. The compacts were sintered at a temperature range of 600 o C-800 o C and tested using the American standard test methods for shrinkage, warpage, absorption and strength. Results show that the composite body containing bentonite as binder and pressed at 10,000 psi had the best green strength, greatest fired strength and also lowest shrinkage value. It is therefore deduced that composite body from waste soda lime silica glass, with the addition of bentonite as binder and pressed at 10,000 psi will make good quality paving tiles.
