The effect of high teteinperatures on the compressive strength and abrasion resistance of mortar fabricated by using lead' slag extracted from recycling of the spent batteries in the homely workshops as fine aggregates was experimentally investigated. The tine lead slag (FLS) was used as a partial replacement of the total'fine aggregate (TFA), sand, by different percentages ofvolume (FLSffEA = 0, 10,20,30 and 40%). Test specimens were subjected to high temperatures ranging from 200°C to 700°C step 100°C. The exposure time after reaching the desired target temperature kept at two hours. The sequence of the residual unstressed test was followed. The weight loss and the relative compressive strength (strength of heated specimen to that of the corresponding unheated specimen) were determined. The weight loss of the heated and unheated specimens due to exposure to abrasive wear was also calculated. Test results indicated that, at certain FLSfTEA%, the relative compressive strength decreased gradually with high temperature up to 500°C and after that it showed a sudden drop with further increases in temperature. The abrasion resistance decreased with increasing high temperature. The compressive strength and abrasion resistance of mortar increased up to replacement of 20% of sand by F'LS and after that it decreased but still higher than that of 100% sand. Both compressive strength and abrasion resistance of FLS mortar relative to those of 100% sand enhanced clearly with the presence of FLS at temperature above 5OO0C
