“…According to Barros et al (2020), soil-cement blocks with the use of ornamental stone wastes and polyester resin using methyl ethyl ketone peroxide as a catalyst showed superior results for compressive strength. The result for water absorption was lower than that of conventional sintered block.…”

This study aimed to analyze potential industrial solid waste that can be added to soil-cement blocks. A narrative literature review was conducted in the Scopus academic database, using as the search criteria keywords related to the topic, such as soil-cement, building materials, soil-cement blocks, soil-cement bricks, physical and mechanical properties, solid waste, life cycle analysis, and civil construction. A variety of industrial solid waste that can be incorporated into soil-cement blocks was observed, such as waste rock, sludge from water treatment plants, wood sawdust, polyethylene terephthalate fibers (PET), vegetable fibers from loofah, hemp fibers, rice husks, brachiaria grass, poultry eggshells, sugar cane bagasse, wheat and barley straw, welding slag, foundry sand, waste from quartzite mining, construction, and demolition, mechanical turning, pulp industry grains, and steel mill co-products. Among the investigated wastes, those that improved the physical and mechanical properties of the soil-cement blocks were grains from the cellulose industry, rice husks, Brachiaria grass, steel by-products with granulated soil-cement blocks and blast furnace slag. The waste that produced no satisfactory results was sludge from a water treatment plant, sugarcane bagasse, and vegetable loofah. Through this research, it was possible to verify that the behavior of soil-cement blocks is influenced by several factors in their manufacture, mainly regarding the type and percentage of incorporated waste. However, it is important to be concerned with its application in waste blocks so as not to increase the environmental impacts in the long term.

“…Barros et al developed a new ecological brick based on dimension stone (limestone) waste and polyester resin, produced and pressed at room temperature, in the model of soil-cement bricks. [10] The new ecological brick showed high compressive strength, low water absorption, good thermal stability and a fire resistance, using 90% by weight of limestone tailing.…”

“…As mentioned in the literature, polymer composites stand out for receiving mineral loads reducing production costs and improving the mechanical properties of these materials. [8][9][10][11][12][13][14] Martias et al added mineral products (vermiculite, mica and glass fibers) as lightweight additives for mechanical reinforcement and thermal insulation in a plaster matrix. [8] Uno et al prepared a new mica/PA6 nanocomposite using sericite mica by melt extrusion.…”

The production of garments with strong thermal control is of paramount importance to improve the working conditions of people who engage in activities under hot sun. From this perspective, bearing in mind the reuse of ornamental stone tailings, the present project aimed at developing a fabric made of polyamide 6 and muscovite, which is a mineral tailing from the cutting and processing of pegmatite rocks and has thermal insulation characteristics. Tensile specimens containing 50%, 70%, 80%, 90% and 95% muscovite by mass are generated in the polyamide matrix, which are submitted to physical index and temperature absorption tests. The addition of 95% mineral filler does not significantly alter the physical characteristics of the samples, since the density increased only from 1.30 to 1.60 g.cm−3. In addition, specimens containing 90% mineral filler in the polyamide matrix reduced the temperature by more than 50%.

“…Soil-cement brick is obtained by the homogeneous mixture of soil, cement and water, in appropriate proportions, which, after compaction and wet curing, delivers a product with durability and adequate mechanical resistance (Motta et al 2014;Saidi et al 2018;Dantas et al 2019;Barbosa et al 2019;Barros et al 2020;Reis et al 2020). Cement is used as a soil stabilizer, allowing better interaction between materials and resulting in improved physical and mechanical properties.…”

This research aimed to evaluate the effect of adding different polymeric waste percentages and types on the physical, mechanical, thermal and durability properties of soil-cement bricks. Tire and PET (Polyethylene Terephthalate) waste were evaluated at 1.5 and 3.0% percentages. The soil was characterized in terms of shrinkage, compaction, consistency limits, particle size and chemical analyses, whereas the waste particles were submitted to morphological characterization. The bricks were produced in an automatic press with a 90: 10 (m/m) soil: cement ratio. The soil-cement bricks were characterized by density, moisture, water absorption, loss of mass by immersion, compressive strength, thermal conductivity and microstructural analysis. PET waste stood out for its use as reinforcement in soil-cement bricks. The best performance was obtained for bricks reinforced with 1.5% PET, which showed a significant compressive strength improvement, meeting the marketing standards criteria, even after the durability test, as well as obtaining the lowest thermal conductivity values. The percentage increase from 1.5% to 3.0% fostered a significant water absorption and loss of mass increase, as well as a significant compressive strength reduction of the bricks.
