| description | Self-Compacting Concrete (SCC) is a new type of concrete that possesses the property of high flow ability, passing ability and stability.This research aims to investigate the properties of the SCC produced by using locally available materials and to study the effect of using local rocks as a coarse aggregate such as quartzite, dolomite and limestone with two replacement ratio 50% and 100% of traditional coarse aggregate (gravel). The SCC mixes prepared with full and 50% replacement of quartzite gives higher compressive strength, splitting strength, flexural strength and ultrasonic pulse velocity compared with mix that contained gravel with percentage of enhancement (11.9%), (9.5%), (12.4%) and (2%); respectively for fully replacement at 28 day.On the other hand, it has been noticed that the concretes prepared with full and 50% replacement of dolomite give lower compressive strength, splitting strength, flexural strength and ultrasonic pulse velocity compared with mix that contained gravel with percentage of detraction (10.3%), (4.8%), (5.9%) and (1.2%); respectively for fully replacement. Also, for both full and 50% replacement; limestone exhibits the same behavior of dolomite but with larger percentages of detraction which are (24.2%), (33.3%), (27.1%) and (3.6%). |
