Abstract
Large amounts of glass and limestone wastes are accumulating every year. Disposal of wastes of limestone factories , recycled container glass ( battles) and wastes of industrial glass is a rapidly growing problem for environment, so research for alternative utilization of these disposals is needed. In this respect, the objectives of this study are to investigate the possibility of producing new mortar containing crushed limestone and glass combinations instead of natural sand . In the present research program, in which mortar has been produced with different ratios of substitution (25%, 50%, 75% and 100%) of natural sand with new mixture of waste limestone and glass. The mechanical properties of the mortars including compressive strength, tensile strength and density were tested. Results show the increasing of compressive strength with an increase of replacement ratios of limestone and glass, at level 25% and 50 %, the highest compressive strength after 3and 7 days was achieved by specimens 50% of crushed limestone and fine glass. The difference is however significant and equals about (21%) in relation to conventional mortar ,while there is an increase of (11%) in the tensile strength of mortar . Hence it is concluded that combined usage of limestone and glass, will be suitable instead of using natural sand in mortar of cement at specified replacement level.
