TL;DR: This study uses machine intelligence algorithms with individual learners and ensemble learners (bagging, boosting) to predict the strength of (HPC) prepared with waste materials and suggested that the individual model response is enhanced by using the bagging and boosting learners.

TL;DR: In this paper, the authors present a comprehensive review on the workability and mechanical properties of fiber reinforced recycled aggregate concrete (FRAC) and highlight the most promising and feasible strength enhancement methods for the FRAC mainly using steel fiber, polypropylene fiber (PPF), basalt fiber (BF), and glass fiber (GF).

TL;DR: In this paper, the authors produced eco-friendly and thermal efficient normal and lightweight concretes with different dosages of sawdust as replacement of sand and showed that volumetric shrinkage and concrete density decreased while water absorption increased with the increase in sawdust percentage.

TL;DR: In this paper, the effect of multi-walled carbon nanotubes (MWCNTs) inclusion on elevated temperature properties of normal weight concrete (NWC) and lightweight concrete (LWC) was evaluated by conducting material property tests namely compressive strength, tensile strength, mass loss, elastic modulus, and stress-strain response under unstressed and residual conditions in the range of 23°C to 800°C.

TL;DR: In this article, a new eco-friendly and effective strength-enhancing technique that involves synergistic use of vacuum-based encrusted RCA and fiber reinforcing technique was applied to augment the mechanical performance of RAC and promote its structural applications.
