“…It is not having porous structure but its lamellar structure increases the strength carrying capacity. Digital microscopy showed that conventional concrete mixes were more porous leading to matrix cracking, but the mixture of quarry dust-waste plastic substitution resulted in refined matrix densification (Bahoria et al 2017 ).…”

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.

“…The popular trend of research is the use of various waste aggregates such as: fly ash, rubber aggregate, blast furnace slag, rice hush ash, palm oil fuel, pumice powder, polyethylene, volcanic ash, glass powder, paper sludge ash. There are still valid attempts to use less known light aggregates such as lytag [20,21]. The issue of using waste aggregate obtained from coconut oil production was discussed by Alengaram [11], who compared the thermal insulation properties of the obtained concrete with traditional materials such as bricks or plain concrete.…”

The leading theme of the paper was to study, how the use of lightweight concrete based on waste aggregates, characterized by significant mechanical strength and increased thermal insulation, affects the properties of building partitions and contributes to possible economic savings, so as to properly design and select materials required for the construction process.The work presents the composition of lightweight concrete samples made of waste lightweight aggregates as well as their physical and mechanical properties. It includes calculations concerning floor loading and heat transfer coefficient of building partitions made of the presented lightweight concretes. Calculations provided the basis for assessing the impact of particular parameters on compressive strength and thermal insulation of walls and floors. The paper additionally describes concretes made of waste aggregates in the form of lytag (Pollytag) and slag. Based on the research, it was found that concrete containing Pollytag had the lowest density value and thermal conductivity coefficient. These parameters translated into reduction in the weight of the slab in question by more than 40% and allowed to save 25% of steel compared to an analogous plain concrete slab. The decrease in heat conductivity coefficient did not result in a significant increase in thermal insulation of building partitions.

“…One of the measures to achieve this purpose is to replace the concrete cement, partially or totally with other cementitious materials that possess pozzolanic proprieties such as heating plants ash, blast furnace slag, metakaolin, etc. [6]. For the aggregates, materials such as industrial or agricultural waste can be introduced as part of the concrete aggregate.…”

The use of concrete has always been an important construction material used throughout the construction industry in the world. The objective of this study is to explore the potential of using lightweight concrete block mixing with plastic waste and additional plastic material as a sustainable construction material for constructing the demising wall in the current construction industry. The research is conducted quantitatively through experiments to test the density and strength of the materials. A series of experiments are conducted based on two types of plastics which are Polyethylene Terephthalate (PET) as replacement of coarse aggregate and Polypropylene (PP) fibres which corresponds to the percentage of cement mass added into the concrete mix and each with a different percentage to observe the variations throughout a series of tests. The findings show that concrete mixing with 0.5 % of Polypropylene (PP) fibres showed outstanding results in the compressive strength compared to the control specimen and PET specimen. However, if comparing the amount of recycled waste incorporated into the same size of lightweight concrete block, the PET has a higher recycling rate which is 27 times the amount of PP fibres. From the findings, the research will contribute to a wider range of sustainable building materials choices for the designer or architect in the project.
