| Abstract | ||
| In this study, two types of mixes were adopted by using two grading of coarse aggregate. The practical side of this study was to produce no-fine aggregate concrete by using crushed clay brick aggregates. The durability of the produced concrete and internal sulfate attack was studied. For durability assessment, it is found that the no-fine concrete made with crushed brick aggregate lost about (15-25) % of its compressive strength after being subjected to 60 cycles of wetting and drying with age 120 days. The curing condition showed that the water curing improved the compressive strength with a rate higher than that when sealed or air dry curing were used. The crushed brick no-fine concrete deteriorated in compressive strength after exposure to internal sulfate attack for 60 cycles; the percentage decrease was about (23.33-25) and (25-27.5) % for 0.57 and 0.83sulfate content respectively. | ||
