The thermal performance of economical housing located in hot climates remains a pending subject, especially in emerging economies. A cellular concrete mixture was designed, considering its thermophysical properties, to apply the new material into building envelopes. The proposed materials have low density and thermal conductivity to be used as a nonstructural lightweight construction element. From the design stage, a series of wall systems based on cellular concrete was proposed. Whereas in the second phase, the materials were analyzed to obtain the potential energy savings using dynamic simulations. It is foreseen that the energy consumption in buildings located in these climates will continue to increase critically due to the temperature increase associated with climate change. The temperatures predicted mean vote (PMV), electric energy consumption, and CO2 emissions were calculated for three IPCC scenarios. These results will help to identify the impact of climate change on the energy use of the houses built under these weather conditions. The results show that if the conventional concrete blocks continue to be used, the air conditioning energy requirements will increase to 49% for 2030 and 61% by 2050. The proposed cellular concrete could reduce energy consumption between 15% and 28%, and these saving rates would remain in the future. The results indicate that it is necessary to drive the adoption of lightweight materials, so the impact of energy use on climate change can be reduced.

“…Uma das maneiras seria o reaproveitamento mais rentável da escória secundária de alumínio. Font (2018) trabalhou com o desenvolvimento de concreto celular baseado na mistura de cimento Portland comum e pó de alumínio comercial. O concreto celular pode trazer benefícios de custo e desempenho quando comparado com os materiais de construção tradicionais.…”

“…In a recent research work, Font et al (Font et al 2018) presented a novel alternative cellular concrete development, where the functional properties and carbon footprint were assessed. Three cellular systems were studied: i) TCC based on OPC and commercial aluminum powder (A); ii) GCC by using fluid catalytic cracking residue (FCC) or BFS as a precursor, activated by a traditional activating solution (NaOH, plus commercial waterglass (WG), i.e., sodium silicate), and aerated by means recycled aluminum foil (RAF); iii) Eco-cellular concretes, with a similar composition to GCC, where commercial waterglass was replaced with rice husk ash (RHA).…”

“…et al(Font et al 2018) analyzed the physical properties of each alternative material (GCC and ECC systems) by its relative values in relation to traditional cellular concrete ones (TCC) to obtain the natural density (ϑd) and compressive strength (𝜗 𝑠 ) ratio coefficients. The authors concluded that the relation between natural density and compressive strength was direct for the FCC samples and inverse for the BFS samples.…”

Cellular concrete is an alternative to conventional concrete as a low-density and high-insulating building material. The eco-cellular concretes (ECC) based on the geopolymer technology have been recently introduced by the scientific community. A form of ECC was herein studied, in which the fluid catalytic cracking residue and the blast furnace slag were employed as precursors, the rice husk ash was utilized as an alternative silica source in the activator and the aerating reagent was replaced with recycled aluminum foil. Field emission scanning electron microscopy, optical microscopy and the ImageJ software were employed to characterize the void distribution. Bulk density and porosity were determined by hydric tests. The results revealed that lowest densities without strength loss were obtained when the cementing matrix had a homogeneous void-system: similar spacing between pores, narrow size ranges and non interconnected pores. A relation between open/close porosity with both density and thermal conductivity was established.
