“…On the other side, cement and construction composites have great interest due to the different applications and benefits they provide. One of the recycling methods is the use of polymer waste, solid byproducts, natural waste, and bricks in construction materials, such as composite blocks and lightweight partitions, to share with the waste management. − Several features, such as lightweight, high strength and elasticity, easy processing, corrosion resistance, low cost, and weathering resistance, make them alternatives to commercial aggregates in modern building and low-density construction applications. − Composites are included in different forms and types due to the durability and improved properties, such as reinforced concrete, reinforced plastic, cement, polymer–cement composite, fiber–cement composite, and fiber–polymer composite. , The global consumption of plastic in the building and construction markets is expected to be duplicated in 2027 with more intense studies. The influence of adding waste powders of concrete bricks and recycled polyethylene terephthalate on mortar was studied in novel improved construction composites.…”

The hazards of polymer waste and emitted gas on the environment pose a global challenge. As a trial to control this, the current work aims to reuse the polymer waste mix (PM) as fillers in calcium silicate to prepare new composites of environmentally friendly polymer concrete. PM was first subjected to treatment to obtain treated PM (TPM) and then was filled in new dicalcium silicate cement with different concentrations. The microstructural characterizations declare the successful preparation of the dicalcium silicate base material. After the curing reaction, the precipitated carbonate main product is responsible for the gained properties. The CO 2 uptake% in the proposed composites reached 16.6%, referring to the successful storage of CO 2 gas during curing. The treatment reaction led to an increase in the flexural and compression strengths due to the strengthening of the polymer waste mix−cement interface; the strengths were increased gradually with more contents of TPM fillers. 7% TPM−cement concentration achieved the highest flexural strength and compression strength of10.2 and 12.7%, respectively, compared with blank cement. The used polymer improved slightly the pull-off force of the prepared cement, and 7 and 5% TPM−cement composites have the maximum values. All the proposed composites passed the impact testing without failure, where the combination between the polymer waste and silicate cement resulted in a stable composite surface. Compared with the blank, the different concentrations of TPM−cement composites show more stability against water absorption. In addition, the proposed composites and blank cement have a very low carbon dioxide emission. The ability to recycle the polymer waste, form new type of low-energy silicate, improve the mechanical and surface properties, uptake CO 2 gas, and reduce gas emission makes the proposed polymer waste mix−cement composites as environmentally friendly construction products.

“…AAMs [6] having recycled PVC and glass aggregates are better than the ordinary Portland cement (OPC)-based composite in terms of mechanical properties, energy absorption, thermal conductivity, and carbon footprint estimation AAM [7] can be used to create high performance concrete and lightweight concrete. The high performance AAM has rapid strength gain with high ultimate strengths.…”

This paper envisages application of alkali activated materials(AAM) with lime as rural technology. The AAM is similar to Geopolymer but it has lot of differences.Low Mole AAM is manufactured using sodium hydroxide of 2, 3, 4 and 5 moles and sodium silicate as double the weight of Sodium hydroxide. The low mole solutions are easy to manufacture and ease of handling. The solution is used instead of water in lime-Surkhi and lime-red soil blocks. The blocks manufactured are tested for weight, water absorption and compressive strength. The results showed increase in density, decrease in water absorption and increase in strength with increase in moles of alkaline solution.

“…A investigação sobre a substituição total de areia por PVC e vidro reciclado demonstrou uma oportunidade de se obter um compósito cimentício leve, com aumento do índice de absorção de água e aumento da capacidade de absorver energia [32]. Essa aplicação apresenta-se como uma interessante via para reduzir a poluição de vidro e polímero.…”

O descarte do vidro pós-consumo ainda é um desafio para a indústria, ainda que este seja um material de inúmeras possibilidades. Aplicá-lo adequadamente na retroalimentação do ciclo produtivo é uma etapa essencial para a sustentabilidade de toda a cadeia produtiva do vidro. Nessa perspectiva, ao aplicar o vidro do pós-consumo no desenvolvimento de outros produtos a partir da sua reciclagem há benefícios com agregação de valor para ambas as linhas de produção e para toda a cadeia produtiva. Este artigo de revisão narra sobre o tema. Buscou-se, de forma didática, explanar a atual situação da reciclagem do vidro a partir da literatura publicada, contemporânea, sobre essa viabilidade sustentável. Concluiu-se que o emprego do vidro pós-consumo, seja no ciclo produtivo de vidro ou como constituinte de outros produtos, apresenta potencial para elevar o nível de sustentabilidade da indústria vítrea, embora não tenha sido realmente empregado esse potencial na prática, haja vista o baixo percentual de reciclagem de vidro no Brasil.
