Abstract: This dissertation presents the impact resistance, flexural toughness and other properties such as density, compressive and tensile strength, modulus of elasticity and drying shrinkage of both plain and fiber-reinforced lightweight aggregate concrete. Effects of coarse and fine lightweight aggregates, silica fume, and steel fibers are studied and discussed. The results are also compared with those of normal weight concrete. The impact resistance of the concrete was determined using instrumented drop-weight testing equipment. Expanded clay type of lightweight aggregate and steel fibers were used for the concrete. The compressive strength of the lightweight aggregate concrete ranged from approximately 40 to 80 MPa. The results indicated that high compressive strength and density are desirable for good impact resistance of plain concrete, and the incorporation of the steel fibers improved the impact resistance substantially.
