Producing lightweight concrete by using Scoria aggregates Available in Syria and study its mechanical and physical properties


Abstract in English

This research deals with producing structural lightweight aggregates concrete (the density is less than 1920kg/m3 and compressive strength is more than 17.2Mpa according to ACI 213R-03) by using scoria aggregates. Several concrete mixes have been designed with different proportions of scoria aggregates. The cement content (c=450 kg/m3), the ratio (w/c = 0.36) were kept constant in all the mixes. Different tests were performed to determine some properties of product concrete such as density, compressive strength and splitting tensile strength. The density of product concrete was in the range of (1752-1917 kg/m3), compressive strength was in the range of (22.2-32.8Mpa), and the splitting strength was in the range of (2.3-3.2Mpa). The study demonstrated the possibility of production concrete achieved the Requirements of the American code ACI 213R-03 for structural lightweight concrete.
