“…It has been reported in the literature that flexural strength decreases with the increase of plastic waste content [11,19,24]. However, Ramadevi and Manju [21] reported that flexural strength of the specimens containing PET waste increased gradually with increase in the replacement percentage.…”

Plastic waste is a silent threat to the environment, and their disposal is a serious issue. To sort out this issue, many efforts were made to reuse the plastic waste, but no significant results were achieved. On the contrary, concrete being the widely used construction material is facing problem due to unavailability of ingredient material (sand and coarse aggregate). In this study PET (polyethylene terephthalate) aggregates manufactured from the waste un-washed PET bottles in shredded form were used to partially replace fine aggregate and coarse aggregate in concrete in various percentages (0%, 5%, 10%, 15% and 20%). Various tests like workability, compressive strength, flexural strength, water permeability, abrasion resistance, dynamic and static modulus of elasticity were performed. The micro-structural analysis of the specimens was carried out using an optical microscope. It was found that the workability, compressive strength, flexural strength, dynamic and static modulus of elasticity decreased with the increasing amount of PET waste in concrete. Water permeability of concrete was found to increase with increasing amount of PET waste. In both the cases, i.e., when fine and coarse aggregates were replaced with PET waste, an improvement in the abrasion resistance of concrete was found.

“…Estudos reconhecem que a incorporação desses resíduos e rejeitos em materiais cimentícios pode reduzir custos e promover benefícios ambientais (SAIKIA; BRITO, 2014;TONET;GORNINSKI, 2013;FRIGIONE, 2010). Assim, o que se observa na literatura científica é uma significativa quantidade de estudos com concretos e incorporação de resíduos poliméricos.…”

“…Por exemplo, observa-se nos estudos um impacto negativo maior na resistência à compressão do que na resistência à flexão quando se incorporam resíduos em substituição ao agregado miúdo natural (SAIKIA; BRITO, 2014;BATAYNEH;MARIE;ASI, 2007). Considerando esses aspectos, objetivou-se neste artigo avaliar o desempenho de dois materiais da construção civil com incorporação de rejeitos da coleta seletiva que possuem diferentes esforços mecânicos; o primeiro, as placas cimentícias, para as quais a resistência à flexão é um fator preponderante para seu adequado desempenho mecânico; e, o segundo, os pavers, cujos esforços compressivos são decisivos para sua viabilidade de uso.…”

Resumo Analisou-se o desempenho físico-mecânico de placas e pavers com incorporação de rejeitos da coleta seletiva do município de Blumenau, SC. Tais rejeitos são compostos de orgânicos, polímeros, papéis, vidro e têxteis, que foram reduzidos de tamanho (2,4 mm a 19,0 mm) e substituíram o agregado miúdo natural nos percentuais de 5%, 10%, 20% e 30%. Para o compósito no estado fresco verificou-se o índice de consistência, e no estado endurecido determinaram-se massa específica aparente, absorção de água e resistência à compressão. As placas foram submetidas ao ensaio de resistência à flexão e à análise de microscopia eletrônica de varredura. A massa específica aparente das placas variou de 0,8 a 1,6 g.cm-3, e dos pavers, de 1,78 a 1,84 g.cm-3. Para menores quantidades de rejeitos incorporados, os dois materiais apresentaram índices de absorção de água que satisfazem as exigências de normas correlatas. As placas apresentaram valores de resistência à compressão que variaram de 4,7 MPa a 14,6 MPa. Na flexão, os valores atingidos foram de 0,1 MPa a 1,8 MPa. Os pavers alcançaram valores de resistência à compressão entre 10,8 MPa e 18,7 MPa. Pavers com 5% de incorporação de agregados de rejeitos seriam passíveis de ser aplicáveis em calçadas e meios-fios desde que estudos futuros garantam sua durabilidade.

“…Pattengill and shutt (1973) were the first who used the grounded powdered glass as pozzolanic material to replace the cement partially (Pattengil & Shutt, 1973).Various research works have tackled the topic of incorporating glass waste in concrete mixtures to establish a ground for its usage in concrete industry (Kim et al, 2014;Bazant & Mayer, 1998;Saikia & de Brito, 2014;Madandoust & Ghavidel, 2013;Tuan, Hwang, Lin, Chen, & Young, 2013;Saribiyik, Piskin,& Saribiyik, 2013;Ling, Poon, & Wong, 2013;Soroushian, 2012;Ismail & Al-Hashmi, 2009;Federico & Chidiac, 2009;Taha & Nounu, 2008;Shi & Zheng, 2007;Topcu & Canbaz, 2004;Metwally, 2007;Schmidt & Saia, 1963;Carpenter & Cramer, 1999;American Psychological Association, 1972). Expansive reactions between amorphous silica (from glass) and alkalis from cement have been noticed to cause disintegration of concrete structures.…”

Glass waste, which is dumped around the world in huge amounts, can be used as a partial replacement of mineral aggregate in concrete industry. This would not only contribute to reducing pollution extent but also enhancing physical properties and durability of concrete. This article reports the mechanical performance of concrete with different replacement percentages of crushed glass waste of cement or fine aggregates before and after being subjected to standard cycles of freezing and thawing. Mechanical performance was evaluated in terms of compressive and flexural strengths. Furthermore, internal damage extent was evaluated using ultrasonic pulse velocity and dynamic modulus of elasticity. The results (average of six specimens for each test) revealed the feasibility of incorporating glass waste in concrete mixtures for the purpose of improving strength and durability; especially in environments where concrete is being exposed to an effective freezing and thawing cycles.
