“…In addition, lightweight aggregate ber-reinforced concrete is increasingly being used in precast concrete structures, providing higher strength members and facilitating transportation. e addition of bers to a concrete mix improves the engineering characteristics of the concrete, for example, ductility, impact strength, and toughness [18]. Properly designed nonstructural ber-reinforced ultralightweight concrete can be easily cut, sawed, and nailed like wood for decorative or insulation purposes [20].…”

Masonry construction is the most widely used building method in the world. Concrete masonry is relatively low in cost due to the vast availability of aggregates used within the production process. ese aggregate materials are not always reliable for structural use. One of the principal issues associated with masonry is the brittleness of the unit. When subject to seismic loads, the brittleness of the masonry magni es. In regions with high seismic activity and unspeci ed building codes or standards, masonry housing has developed into a death trap for countless individuals. A common approach concerning the issue associated with the brittle characteristic of masonry is addition of steel reinforcement. However, this can be expensive, highly dependent on skillfulness of labor, and particularly dependent on the quality of available steel. A proposed solution presented in this investigation consists of introducing steel bers to the lightweight aggregate concrete masonry mix. Previous investigations in the eld of lightweight aggregate ber-reinforced concrete have shown an increase in exural strength, toughness, and ductility. e outcome of this research project provides invaluable data for the production of a ductile masonry unit capable of withstanding seismic loads for prolonged periods.

“…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. This feature allows to decrease the dimensions of structural and non-structural sections and cost of the construction 4,[8][9][10] . Nonetheless, there are some defects in mechanical properties of lightweight concretes, which have prevented it from being used as load bearing structural members in construction industry 3,11,12 .…”

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.

In this study, a rule-based Mamdani-type fuzzy logic (RBMFL) model was developed for prediction of compressive strength of lightweight concretes containing silica fume (SF) and fly ash (FA). Pumice was used as the aggregate in the concretes. In the concrete mixture 0, 5, 10, 15 and 20% of fly ash and 0, 5, 10, 15 and 20% of silica fume, for each value of fly ash content, were added by replacing the cement. The compressive strength of the lightweight concretes was investigated experimentally. Experimental results were used to construct the fuzzy logic model. In the study, the values obtained from the model and experiment were divided into five groups (each group has five experimental results), according to the FA and SF contents, to evaluate approximate reasoning ability of RBMFL model. As a result, RBMFL model has shown satisfying relation with experimental results, which suggests an alternative approach to evaluation of compressive strength of lightweight concretes containing silica fume and fly ash.
