“…Therefore, one of the most efficient strategies for the reduction of greenhouse gases produced by space heating is the adoption of products with increased thermal insulation performances [1][2][3]. Among them, Autoclaved Aerated Concrete (AAC) is becoming a quite common solution for the realization of sustainable concrete masonry units (CMUs), to be used in the construction of new buildings, as well as in the retrofitting of existing ones [4][5][6][7][8][9][10]. AAC is a porous lightweight concrete whose cellular structure is generally obtained through a gas-producing chemical reaction of sand, lime, gypsum, and cement slurry, with the addition of an expanding agent (usually aluminium powder).…”

To satisfy the increasing demand of energy efficient buildings, AAC manufacturers are nowadays encouraged to produce blocks with ever lower densities. However, a compromise between energy-saving requirements and mechanical performances is needed to ensure structural safety, as well as an adequate structural durability. This paper reports a comprehensive experimental study on AAC mechanical properties (compressive and tensile strengths, as well as fracture energy), and on their dependency from material density and moisture content. The collected data are compared with some well-known analytical relations taken from the literature, which are often used for the calibration of mechanical parameters required for mathematical and/or finite element modelling of AAC load-bearing masonry, as well as of AAC masonry-infilled framed structures. These comparisons highlight some critical issues in the formulation of analytical relations having a general applicability; however, it was found that RILEM suggestions are appropriate for the considered AAC productions, at least for densities greater than 400 kg/m3.

“…Binding material such as cement is greatly used in all kinds of concrete to bind all other constituent materials together to give high strength and hardness. Besides that, the manufacturing of cement creates huge number of environmental problems [10][11]. Cement industry is the source for the release of 10% of the total global carbon dioxide (CO2) emissions.…”

Aerated concrete, which is manufactured from binding material, sand, foaming agent and water, is currently being utilized in the construction industry because of its lightweight and durability. The binding material, cement, along with other materials used in the concrete produces huge carbon footprints during its fabrication. The utilization of natural aggregates name as coarse aggregates depletes the natural resources of the country. Therefore, huge amounts of agricultural wastes have led scholars to investigate the effectiveness of replacing conventional materials used in concrete with agricultural wastes. In the current study, rice husk ash (RHA) was used as supplementary cementing material, thereby reducing the amount of cement used in aerated concrete (AC) mixture will reduce carbon footprints. The experimental and numerical analysis were conducted to investigate structural behavior of reinforced RAC- B beams subjected to flexural load. Parametric study on structural performance of RAC- B beam under flexure were conducted using finite element analysis (FEA). From the experiment and FEA. Results from the parametric study showed that RAC-10%RHA-B with higher depth structurally performed better compared to RAC-B under flexure with greater load carrying capacity, lesser maximum deflection, and less cracks developing in the tension area.
