“…From related studies, it was found that using plastic flakes as an aggregate of concrete blocks would make the block's compressive strength decrease. For example, according to Rahmani et al (2013), the compressive strength of concrete blocks decreased more than 50% when plastic flakes replaced sand at 3%. Mazouk et al (2007) found that when replacing sand with plastic flakes in excess of 10%, the compressive strength of a concrete block will reduce compared to the concrete without plastic flakes.…”

“…With ten percent PET the blocks had the compressive strength of 55 and 53 MPa. Rahmani et al (2013) used ground and filtered plastic, (ranging from 7 mm to 150µm, with the largest percent on sieve at approximately 2 mm) to form concrete blocks, and then compared the compressive strengths of the blocks by replacing sand at 0, 5, 10, and 15%, applying a [cement : gravel :sand ] ratio of 1: 2: 1.5 and water to cement ratio (W/C) = 0.422 and (W/C) = 0.54. The results showed that 5% replacement was the best compression ratio increasing from the reference samples of 8.86% (W/C = 0.42) and 11.97% (W/C = 0.54).…”

Plastic waste is increasing continuously, especially in the form of throw away packaging such as drinking water bottles, designed to be convenient, inexpensive, and accessible. Plastic disposal, however, is difficult and has a lower recyclability rate than other types of materials such as glass and paper. This study presents a method of reducing the amount of plastic waste by recycling plastic containers in architectural work. Non-load-bearing concrete blocks for safe and efficient use can be manufactured using plastic flakes as an alternative material aggregate. This study developed such block sand tested them for compressive strength integrating four major factors:(1) the cement to aggregate ratio, (2) the water to cement ratio, (3) the size of plastic flakes used and (4) the proportion of plastic flake that replaced sand. The findings revealed that using a ratio of 1:3 cement to aggregate, where the aggregate mix comprised of 20% small and medium sized (combined at 1:1) plastic flakes plus 80% sand and a water to cement ratio of 0.5, provided the optimal compressive strength to form a concrete block that can be used to construct a non-load bearing wall.

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.

“…The decrement can be attributed to the fact that particles of PET waste have angular and non-uniform shapes resulting in less fluidity [34]. Decrement in workability can also be due to the high specific surface area of PET particle compared to the sand which results in more friction between the elements resulting in low workability [35].…”

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.
