The aim of present work was to study the effect of adding garnet and fly ash on the physical and mechanical performance of Al7075 hybrid composites. Al7075 hybrid composites reinforced with varying weight percentage (0 wt.%–15 wt.%) of each of garnet and fly ash were fabricated and characterized for the comparative assessment of their physical and mechanical properties. The physical and mechanical tests such as void content test, hardness test, tensile strength test, impact strength tests, flexural and fracture toughness test were performed for both garnet and fly ash reinforced composites. The finding of results indicated that the addition of 0 wt.%–15 wt.% of garnet increased the void content, hardness, flexural strength, tensile strength, impact strength and fracture toughness in the range of 1.01 %–2.69 %, 33 HRB–88 HRB, 165 MPa–275 MPa, 205 MPa–263 MPa, 12 J–22 J and 0.11 MPa ⋅ m1/2–0.58 MPa ⋅ m1/2 at crack length 0.1 respectively whereas addition of 0 wt.%–15 wt.% of fly ash increased the void content, hardness test, flexural strength, tensile strength, impact strength and fracture toughness in the range of 1.010 %–1.351 %, 33 HRB‐80 HRB, 165 MPa–225 MPa, 205 MPa–236 MPa, 12 J–20 J, 0.11 MPa ⋅ m1/2–0.48 MPa ⋅ m1/2 at crack length 0.1 respectively. Apart from the economic concern and void issue, Garnet indicated better choice of reinforcement as compared to fly ash in terms of mechanical properties.

This paper discusses the possibility of developing a lightweight self-compacting concrete (SCC) with self-curing capabilities. In this regard, a supplementary cementitious material metakaolin, a presoaked lightweight expanded clay aggregate (LECA), and a chemical agent, superabsorbent polymer (SAP), were incorporated in developing a self-compacting self-curing concrete possessing a target strength of 60 MPa through experimental investigations, and the results are reported. The research includes an analysis of basic material properties of constituent materials including fresh properties of concrete and mechanical properties such as compressive and splitting tensile strength. It was inferred from the experimental results that utilization of self-curing agents in SCC has enhanced the mechanical properties when compared with conventional SCC mix. In particular, a combination of 0.3% SAP and 15% LECA gave the optimum strength values. The optimum usage limit of both the materials is presented in this study, and the results prove that SCC can be used as an alternate resource without disturbing the natural resources.

Energy storage systems are becoming increasingly important, with a growing focus on renewable energy sources that provide highly fluctuating output. Therefore, sound decisions regarding the energy storage systems to be employed need to be made, especially with a systematic and semantic approach. This paper considers the problem of evaluation and selection of energy storage technologies (ESTs). The objective of the proposed research is to decide the best technology for energy storage under the novel idea of hybrid multicriteria decision-making technique under fuzzy environment, that is, fuzzy AHP with fuzzy VIKOR. Electrochemical storage, electrical storage, magnetic storage, mechanical storage, and chemical storage are considered as five alternative energy storage technologies. Energy density, life cycles, cycle efficiency, investment level, suitability to climatic conditions, and required space are considered as six main evaluation criteria. Under each of the main criteria, a set of subcriteria are also considered. The weights of main criteria and subcriteria are determined using fuzzy AHP. With the help of the weights of each set of subcriteria, the weights of alternatives are determined using fuzzy VIKOR. Further, with the help of the main criteria weights and the weights of alternatives determined with respect to each set of subcriteria, the final normalized weights of alternatives are determined. Based on these weights, energy storage technologies are ranked. In addition, the sensitivity analysis is carried out to analyze the variation in ranking pattern of alternatives. From the research findings of this paper, the results are found to be more practical as the evaluation is carried out on an objective basis.
