“…More available leftovers from manufacturing processes or municipal solid wastes are artificial fibre wastes, glass fibre, polypropylene, and polyester, and rubbers are also available [66,67]. These materials have a high potential for environmental hazards due to their lower biodegradability and the probability of leaking into the ocean or other public spaces [68].…”

The integration of waste materials in extrudable cement mixtures has the potential to make the construction industry more sustainable by reducing carbon footprints and developing eco-friendly materials. This along with advancements in 3D concrete printing (3DCP) provides engineering and architectural benefits by reducing material waste and costs. In this paper, the impact of waste incorporation on properties of mortar and concrete is examined. The use of waste materials, such as pumice, coal slag, agricultural lignocellulosic residues, and recycled rubber tyres, to improve thermal insulation and durability of cementitious composites is discussed. In addition, the incorporation of air-entraining admixtures with surfactant activity is explored for their indirect effect on thermal behaviour, pore size reduction, and enhancement in concrete properties. This review includes important topics such as a strength resistance to freezing and thawing, fire resistance, plasticising effect, and delay in cement hydration. These findings highlight the benefits of using diverse waste materials in construction, providing a multidimensional approach to waste management, cost optimization, and enhanced construction materials in the context of 3DCP.

“…Many studies approaches are adopted such experimental and simulation methods in producing a sustainable cementitious composites using recycling plastic without compromise its strength properties behavior in general. Furthermore, studies on the use of recycling plastic in cement composites also covered various type of concrete such as lightweight concrete and self-compacting concrete [24][25][26].…”

Recycling plastic waste in construction applications is a common concept for innovative concrete development. Enormous studies have been conducted for the past three decades. Yet, there is a need in understanding the behavior of the plastic, its effects on cement composite, and the possible approaches for extending the usage of plastic waste to be an alternative resource component of cement composites. For the first section, the types of plastic and its characteristic as well as the overview on the plastic production and waste generated are discussed briefly. Further, the paper is focused on the relevant information on the plastic waste in cement composites and the polyvinyl chloride (PVC) plastic as plastic aggregate in cement composites. The review also includes the factors that influence PVC aggregate on cement composites which are physical characteristics of PVC plastic aggregate, the effect on mechanical and permeation properties of cement composites. The paper also examines the possible approaches in improving the PVC plastic aggregate characteristics, which can enhance the usage of PVC plastic aggregate for sustainable construction material.

“…The natural failure pattern of concrete is brittle in nature and also it has the tendency to carry the entire compressive load which is similar for the coarse aggregate (8) . The usage of plastic aggregates in concrete leads to reduce the brittle nature in concrete which will help to increase the sustainability of load carrying capacity of the structures (9) . Usage of this plastic waste will help to reduce the usage of natural aggregates and also leads to the decrease in the usage of natural resources (10) .…”

Objectives:The purpose of the present study is to examine the thermal and impact behaviour of the concrete containing polystyrene waste as aggregates. Methods: The concrete specimens were cast and cured in a conventional way to examine the mechanical behaviour of the concrete. A separate equipment was prepared to determine the impact strength of the concrete as per ASTM D5420-21. The thermal behaviour of the concrete with plastic aggregates were also examined with reference to IS 7861-1 (1975). Artificial Neural Network was also used to predict and compare the properties between both the conventional and plastic concrete. Findings: The mechanical behaviour of the concrete behaves well at Mix 2 when compared to other mixes. The impact strength of the concrete was found to be 98.375 J at Mix3 which was 20.69% higher than the Mix2. At Mix2 the 7 days compression strength in elevated temperature is 16.79 N/mm 2 which was 4.8% higher than the Mix 1 and 31.74% higher than the Mix 3. At 28 days, the compressive strength of concrete containing 50% replacement of aggregate exposed to temperature 50 o c for 24 hours is 26.84 N/mm 2 which shows a better result and resistance in the thermal condition than the other mixes. ANN also gives reliable predicted values which exhibits a clear relation with the inclusion of the plastic aggregate and concrete matrix with some minimum errors. Novelty: From the experimental investigation it was observed that the plastic concrete fails in the transition zone of concrete due to the weaker bonding between the plastic aggregate and cement matrix. The plastic aggregate has not undergone any crushing failure in the concrete specimens when compared to the conventional aggregate. Thus, this solid polystyrene waste can be used as an alternative material for coarse aggregate in concrete.
