“…On the other hand, it can be seen how the incorporation of expanded polystyrene residue with graphite in the manufacture of mortars reduces flexural strength. This is because preferential breakage points occur between EPS spheres and plaster mortar matrix, thus generating greater heterogeneity that negatively affects the mechanical behaviour of the material [55]. On the other hand, the incorporation of mineral wool residue improves the flexural strength of the hardened plaster mortar.…”

The high demand for natural resources and increased industrial activity is driving the construction sector to search for new, more environmentally friendly materials. This research aims to analyse plaster mortars with the incorporation of construction and demolition waste (CDW) to move towards a more sustainable building sector. Three types of aggregates (natural, recycled concrete and recycled from ceramic walls) and two types of insulation waste (expanded polystyrene with graphite and mineral wool) have been added to the plaster matrix to evaluate its mechanical and physical properties and its suitability in the elaboration of prefabricated materials. The results show how plaster mortars made with recycled aggregates have higher mechanical resistance than conventional plaster without incorporating sand. The incorporation of crushed mineral wool residues improves the flexural strength of plaster mortars and their application in the execution of prefabricated panels. Likewise, the expanded polystyrene residues reduce the final density of mortars, improving their behaviour against water absorption and reducing the final thermal conductivity of plaster material.

“…For PC/aggregate replacement for concrete mixtures by 3%, 10%, 20% and 50% led to reduction in compressive strength by 6.8%, 27.2%, 46.1% and 63.9% respectively [4]. Another study conducted by Aocharoen and Chotickai [9], were they used a PC/aggregate replacement by 15% resulted in reduction in compressive strength by 16.24% and 14.87% for ages 7 and 28 days respectively. Furthermore, according to Da Silva et al, [5], a higher reduction in compressive strength when using PET plastic flakes was reported compared to plastic pellets for 10% sand substitution.…”

“…Previous studies were conducted on both concrete and mortar mixtures containing recycled plastic of various types such as polycarbonate (PC) [4], polyethylene terephthalate (PET) [4,5,6,7] and high-density polyethylene (HDPE) [8,9,10]. Some plastics were lightly washed and grounded using a blade mill [5,6,7,10] and others were melted at high temperatures, extruded, and cut to the desired size [5,9,11]. Furthermore, the replacement of the sand was volume-based replacement [4,5,9,10] or weight-based replacement [6,7].…”

“…It also observed the use of plastic in making light weight concrete by mixing it in the form of fine and coarse aggregate by first bifurcated types of plastics with a cleaning and shredding process [6]. Aocharoen and Chotickai studied the use of HDPE plastic as an aggregate in place of river sand especially in cement mortar mixes at various fractions from 0% to 100% by volume [7]. Moreover, the quantity of substituting fine aggregates through impure PET waste bottles by weight (5%) in concrete specimens improves durability parameters as compared to conventional ones [4].…”

In the Modern era, construction activities continuously increase as a result of urbanization and hence have a huge demand for natural materials to fulfil the needs. Due to this, the extraction of beds at a large scale is required to excavate the natural aggregate and thus it disturbs our precious environment. Parallel to this, there are a lot of waste materials like PET plastic waste available in the surrounding which has the potential to substitute the fine and coarse aggregate by forming a durable structure. Sustainable disposal of industrial waste is not an easy task as it contaminates the natural sources of water such as rivers, lakes, ponds and also depletes the land area by dumping over it. The present work draws an overview to remove the mentioned issue by effective utilization of PET plastic waste by performing physical, chemical, mechanical, and microstructure analysis in cement mortar mixes. A total ten cement mortar mixes of Rich mix mortar (1:3) and Lean mix mortar (1:6) proportions (each of five) were prepared by substituting PET plastic waste [sizes 1mm (68%), 2mm (22%), 3mm (6%) and 4mm (4%)] over fine aggregate at a replacement level from 0% to 20% at an interval of 5% to evaluate the various important properties like specific gravity, bulk density (loose), fineness modulus, compressive strength, flexural strength, ultrasonic pulse velocity parameters etc. A positive outcome is obtained at a 5% replacement level due to dense homogeneous mortar mix and improved workability. It also enhances strength parameters through which the rheological characters of mortar mixes are sustained. Internal structural analysis is performed by microstructure tests like X-ray diffraction (XRD), Scanning electron microscopy (SEM), and Energy dispersive spectroscopy (EDS) methods on raw material. Utilization of PET as a partial replacement for conventional river sand may have an opportunity to preserve over natural resources with alternative building materials. The finding represents that all PET-based mortar mixes may be incorporated in plaster work of structural walls, column, etc.
