Abstract
In this work, sheet glass waste was used as a replacing material instead of natural gravel. The mix proportion of cement-gravel - sand was (1:1.5:3) and natural gravel was subjected in each mix at different percentages (10%, 20%, 30%, 40%, and 50%) all the specimens made with natural gravel were repeated with the same specification but instead of natural gravel, sheet glass waste were subjected. Compressive strength for cubic specimens were tested after immersing for different period (1, 7, 14, 28) days and a comparisons made between the concrete of waste glass with the conventional, concrete. Because of similarity of thestrength of compressive results of both glass and gravel. concrete, it was concluded that glass waste could replace natural gravel in concrete. It was obvious that all the percent's show this behavior, but still at a particular percent's glass concrete results were even better than gravel concrete. On the other hand glass concrete specimens were less absorbing than gravel concrete when studying the water absorption. Beside the maximum immersion time is the best to improve the properties to both series (glass, gravel).
