“…In terms of strength and water absorption resistance, the best performance was obtained at two different waste percentages, 1% and 5% aluminum, respectively [26]. It was determined that the use of aluminum waste with a maximum size of 4.74 mm in cement-based mixtures by replacing them with sand sharply reduces compressive strength [27]. According to results, it was concluded that both the amount of binder and types of aggregate play a very important role on mechanical properties of mixtures.…”

Sustainable waste management is becoming more and more important in the construction industry due to increasing waste costs as well as environmental effects. As a result of increasing level of wastes and environmental damage, the use of these wastes has become the focus for beneficial construction activities and sustainable industrial applications. This study presents experimental results on the effect of industrial wastes on the performance of cementitious mixtures. The scope of this study, therefore, was to assess the effect of waste aluminium on physical and mechanical properties of cement based mixtures prepared in different compositions. Consistency, bulk density, porosity, absorption, flexural and compressive strength tests were carried out on mixtures produced by using waste aluminium aggregates in different percentages instead of fine aggregate. Results showed that mixtures prepared with 4% aluminium aggregates had the highest water absorption and porosity. With the addition of %1 lathe waste, it was observed that the flexural behavior of mortar was maximum and the optimum percentage for flexural strength was noted. In addition, when mixtures produced with the same percentage of aluminium were compared, the amount of binder played a significant role on both compressive and flexural strength. Results have shown that to incorporate aluminium into mixtures can be a suitable solution for recycling in industrial applications.

The sustainable utility of industrial waste and by‐products is crucial to reduce environmental impact. Particularly relevant for the cement and concrete industry, where recycling and utilization of industrial waste can help to replace normal concrete and promote stable growth. One such waste material is aluminum computer numerical control waste (ALCNCW). This study investigated the performance of reinforced concrete beams incorporated with ALCNCW. It was decided to use the effects of the ALCNCW ratio and the proportion of longitudinal reinforcement as parameters. A total of 12 reinforced concrete beams were cast and tested with varying levels of lower reinforcement ratios (0.0125, 0.0074, and 0.0032) and ALCNCW ratios (1%, 2%, and 3% by weight), in addition to a control beam. The load‐carrying capacity, failure mode, crack patterns, ductility, and serviceability were analyzed. The findings of the experiments demonstrated that the cracking and bending effects of reinforced concrete beams were different depending on the quantity of tension reinforcement and ALCNCW that was used. The results indicate that adding 1% or 2% of ALCNCW to concrete beams has a negligible effect on the load capacity. However, the ductility of the beams was adversely affected. Nevertheless, adding ALCNCW to the concrete mix can still be implemented with a specific ratio. Finally, all 12 beams met the serviceability limit state requirements.
