Today glass is used in many forms and it has a short life due to brittleness and ease of breakage. After breakage it either store until re-use or send to landfills, since the glass material is un-degradable so its stockpiling in landfills considered an unfriendly solution for the environments, thus there is great need to take advantage of glass waste such as using in mortar and concrete as additive.
This research deals with studying the effect of adding (incandescent lamps) as a glass powder waste to cement mortar on mechanical properties, where the glass waste is used as additive after converting it into micro powder, and mixed with cement in the proportions (0%, 5%, 10%, 15%) and then mixed with sand in 3:1 ratio to create cement mortar and then poured into molds.
And then put in humidity basin and after 24 hours the cubes removed from molds and treated in clean fresh water, saline solution where the salt is 3% NaCl- and finally in basal solution where the base is 3% NaOH- for 7, 28 days, and then mechanical tests is made where the test used in this research is the compressive strength.
It has been noted that there are differences in the compressive strength when immersed in various solvents. The samples submerged with water only have higher strength than that submerged in NaCl solution which in turns have higher strength than that immersed in NaOH, also strength increases with immersion time (i.e. Compressive strength of samples submerged at 28 days better than that submerged at 7 days).
