“…Polyethylene terephthalate (PET) mixed with lateritic clay at an increment of 5% up to 20% for making fired bricks results in maximum compressive strength of 5.15 N/mm 2 and maximum modulus of rupture value of 13.20 N/mm 2 with 0% plastic waste which showed that with addition of waste, both compressive strength and modulus of rupture decreased. Water absorption value bated from 10.29 to 6.57% on addition of plastic waste (Akinyele et al 2020 ).…”

The exponential rise in the production of plastic and the consequential surge in plastic waste have led the scientists and researchers look out for innovative and sustainable means to reuse/recycle the plastic waste in order to reduce its negative impact on environment. Construction material, converting waste plastic into fuel, household goods, fabric and clothing are some of the sectors where waste plastic is emerging as a viable option. Out of these, construction material modified with plastic waste has garnered lot of attention. Modification of construction material with plastic waste serves a dual purpose. It reduces the amount of plastic waste going to landfills or litter and secondly lessens the use of mined construction materials, thereby mitigating the negative impact of construction industry on environment. This paper summarizes the developments with regard to the use of plastic waste as a constituent of construction material. Inclusion of plastic waste as a binder, aggregate, fine aggregate, modifier or substitute of cement and sand in the manufacturing of bricks, tiles, concrete and roads has been comprehensively reviewed. Also, the influence of addition of plastic waste on strength properties, water absorption, durability, etc. has been thoroughly discussed. The research studies considered for this review have been categorized based on whether they dealt with the use of plastic waste for bricks and tiles or in concrete for road construction.

“…Despite the fact that the commercial production of bricks from waste products is still limited, the inclusion of these materials in bricks will be beneficial if there is standardization and commercialization being set according to their usage. Akinyele et al (2020) studied the possibility of using various proportions of PET as an additional material in burnt bricks. Figure 14 shows PET burnt brick before firing shrinkage test and Table 5 indicates the result of the utilization of various PET percentages in burnt brick including of 0%, 5% and 10% of PET in terms of firing shrinkage, water absorption, dry density and compressive strength.…”

Recycle Polyethylene Terephthalate (PET) plastic bottles can be used as partial replacement of aggregates to form plastic bricks, silica plastic blocks and PET bricks. By replacing from 0.5 to 5% of PET recycled plastic as partial replacement of fine and coarse aggregate into concrete mixture can be moulded as silica plastic blocks, colour plastic bricks, RePlast bricks and burnt brick to construct a singlestorey house and temporary shelters. Furthermore, by adding 0.5-1.5% of recycled PET fibre in concrete with water cement ratio of 0.65 can increase the compressive strength of concrete. The advantages of using recycled bottles as green construction materials can reduce landfill pollution, conserve natural resources, improve the environment and save sea life from dying. Furthermore, the bottle houses are bioclimatic in design which means it is cold outside and warm inside or vice versa. It can be concluded that by substituting recycled plastic bottles into concrete mixture and transforming into green recycled bricks, they can be used to construct the houses in rural or slump areas where the cost of construction materials are very expensive and limited.

“…The growing demand for sustainable products has encouraged several studies that search for alternative techniques regarding the reuse of waste in construction materials, such as mortars with sugarcane bagasse [ 10 ], cement pastes with açai fiber [ 11 , 12 ], blast furnace slag [ 13 , 14 ], construction and demolition waste [ 15 ], ceramic materials with rice ash water treatment plant sludge [ 16 ], pulp and paper industry sludge [ 17 ], construction and demolition waste [ 18 ], and agricultural waste [ 19 ], as well as concrete with plastic waste [ 20 ]. Therefore, research also highlights the reuse of plastic waste in construction materials [ 19 , 20 ] such as paving [ 21 ], mortar [ 7 ], concrete [ 19 , 20 , 22 , 23 ], fired clay blocks, and bricks [ 24 ], as well as unfired blocks and bricks [ 25 , 26 ], thus showing PET ( Figure 1 a) as an addition in the production of these materials.…”

The ever-growing consumption and improper disposal of non-biodegradable plastic wastes is bringing worrisome perspectives on the lack of suitable environmentally correct solutions. Consequently, an increasing interest in the circular economy and sustainable techniques is being raised regarding the management of these wastes. The present work proposes an eco-friendly solution for the huge amount of discarded polyethylene terephthalate (PET) wastes by addition into soil-cement bricks. Room temperature molded 300 × 150 × 70 mm bricks were fabricated with mixtures of clay soil and ordinary Portland cement added with up to 30 wt.% of PET waste particles. Granulometric analysis of soil indicated it as sandy and adequate for brick fabrication. As for the PET particles, they can be considered non-plastic and sandy. The Atterberg consistency limits indicated that addition of 20 wt.% PET waste gives the highest plasticity limit of 17.3%; moreover, with PET waste addition there was an increase in the optimum moisture content for the compaction and decrease in specific weight. Standard tests showed an increase in compressive strength from 0.83 MPa for the plain soil-cement to 1.80 MPa for the 20 wt.% PET-added bricks. As for water absorption, all bricks displayed values between 15% and 16% that attended the standards and might be considered an alternative for non-structural applications, such as wall closures in building construction.
