“…The compressive strength result for 50% replacement by limestone is found to be satisfactory for structural lightweight concrete, since the lower limit of compressive strength for structural lightweight concrete is 17 MPa [3]. The compressive strength of the concrete is one of the most important factors and is usually used to judge the concrete quality and its fitness.…”

A control lightweight concrete (LWC) mixture made with 50% and 100% of limestone as a replacement of coarse aggregates in weight was prepared. Limestone is used for economical and environmental concern. The concrete samples were cured at 65% relative humidity at 20 °C. The compressive and flexural tensile strengths, elastic modulus and Poisson's ratio of hardened concrete were measured. Laboratory compressive and tensile strength tests results showed that LWC can be produced by the use of limestone. The aim of this study is twofold: one is to design a lightweight concrete with the use of limestone that will provide an advantage of reduction in dead weight of a structure; and second is to obtain a more economical LWC mixture with the use of limestone. Keywords: lightweight aggregate concrete, limestone dust, flexural tensile strength, elastic modulus, compressive strength. Resumo

“…1,2 . Structural lightweight concrete is a popular material in construction industry due to some substantial benefits such as good tensile capacity, low coefficient of thermal expansion and superior heat as well as sound insulation capability [2][3][4][5][6][7] . Furthermore, using lightweight concrete in construction decreases the dead load of the structures and further earthquake forces which reduce the risk for human's life.…”

Nowadays, the use of different waste fibers in concrete has started to increase rapidly due to some reasons such as economic savings and positive effects on the environment. In this study, waste steel wires taken from reinforcement and formwork which were previously utilized in construction projects, were employed in structural lightweight concrete (SLWC). The objective was to investigate the possibility of using this type of fiber as reinforcement in the SLWC. Compressive, tensile, flexural and impact tests were performed for investigating the mechanical properties of 28-day reinforced lightweight concrete specimens with the waste wires. The percentage of wire in the fiber reinforced concrete (FRC) was 0.25%, 0.5% and 0.75% in the volume fraction of the concrete. According to the results, by using waste wires, flexural, tensile and impact characteristics of SLWC were effectively improved. Moreover, it was concluded that waste steel wires could be used as a suitable micro reinforcement in the SLWC.
