Abstract:Pore structure, density, and strenght may vary within a wide range for different types of lightweight aggregate. Hence, not all types of lightweight aggregate are suitable for production of high-strength concrete. In the present work, the significance of various lightweight aggregates on the concrete strenght and density was studied. Twenty-eight-day compressive strengths up to 102 MPa, corresponding to a density of 1865 kg/m3, were obtained. The type of lightweight aggregate appears to be the primary factor controlling both the density and the strength. For high-strength lightweight concrete, it is difficult to predict the 28-day strengths from early strengths because of the influence of the aggregate.
