“…A negative effect on the concrete’s compressive strength parameter was also observed after adding other polymeric materials, such as PET [ 11 , 12 , 14 , 15 , 16 ], EPE [ 18 ], EPS [ 19 , 20 , 21 , 22 ], and rubber [ 41 , 43 , 45 , 46 , 47 ]. However, some authors report that the addition of PET [ 10 , 13 ], EPS [ 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 ], or PP [ 32 , 34 , 38 ] wastes increases the compressive strength of concretes modified with this waste.…”

“…Moreover, post-production waste and post-consumer polystyrene waste were used for the production of concrete on a laboratory scale. This material was used both in the form of ball-shaped regranulate [ 19 , 20 , 21 , 22 , 23 ] and pellets [ 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 ] as an aggregate substitute in amounts from 10% to even 100%. The resulting composite was characterized by low density and better thermal parameters compared to ordinary concrete.…”

“…The compressive strength of concrete depends, to a large extent, on the amount of waste added. The addition of polystyrene recyclate increases [ 20 , 21 , 22 , 23 ] or decreases [ 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 ] the compressive strength of concrete compared to control concrete samples. In addition, recyclate from waste polyethylene and polypropylene was used to produce concrete [ 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 ].…”

In this paper, the influence of post-consumer thermoplastic elastomer (TPE) additive derived from used car floor mats on the physical and mechanical properties of concrete is presented. Waste elastomer (fractions 0–2 and 2–8 mm) was used as a substitute for sand or fine aggregate in the amount of 2.5, 5.0, 7.5, and 10.0% by weight of cement. For all series, the physical and mechanical properties of concrete (for example, compressive strength, flexural tensile strength, water absorption, density, and frost resistance), as well as its microstructure, were tested. It has been shown that post-consumer elastomer waste from used car floor mats in the amount of 2.5% of cement weight can replace sand and gravel aggregate in concrete without reducing their mechanical strength and without changing their microstructure. The compressive strength (after 28 days) of concretes in which the waste was introduced as a substitute for sand and aggregate was 57.0 and 57.2 MPa, respectively (the strength of the control sample was 57.0 MPa). The use of post-consumer waste in concrete allows for a reduction in the consumption of natural aggregate (the addition of 2.5% of waste material saves natural aggregate approximately 20 kg/m3), which reduces the cost of concrete production and also has a positive impact on the environment (i.e., it saves cost and space in landfills, where currently used car floor mat are deposited).

“…EPS concrete is better than ALC for the durability aspect concerning the water absorption behavior. Herki [38] reported that higher water absorption was obtained in the higher content of EPS. He forwarded the reason for poor compaction and entering of water through the channel of voids.…”

Nepal is facing the problem of thermocol wastage, especially in the damping site nearby the urban areas. The thermocol wastage were crushed by a hammer and the extracted expanded polystyrene (EPS) beads was used as aggregates to produce the lightweight concrete. The content of EPS beads was 0, 20, 30, 40, 50, and 60 % by the total volume. Mechanical properties like density, different strengths, and Young’s modulus were experimentally evaluated on ranging percentages of EPS. The 28-day compressive, flexural, splitting tensile strengths and Young’s modulus of the control mixture were 59.9 MPa, 5.21 MPa, 4.43 MPa, and 20898 MPa respectively. The decrease on compressive strength was by 62 %, 72 %, 81 %, 88 %, and 93 % respectively for 20 %, 30 %, 40 %, 50 %, and 60 % EPS content respectively. It was 26 %, 41 %, 51 %, 57 %, and 69 % for flexural strength, 46 %, 60 %, 70 %, 80 %, and 88 % for the splitting tensile strength and 45 %, 56 %, 61 %, 70 %, and 77 % for Young’s modulus respectively. Drying shrinkage, freezing and thawing, and water absorption tests were conducted to evaluate the durability of EPS concrete. All properties were compared with the auto-cleaved lightweight concrete (ALC). It revealed that the EPS beads extracted from the thermocol wastage can be re-used to produce the structural and non-structural concrete depending on its percentages. It can easily solve the never-decomposing problems of thermocol wastage. Moreover, ALC can be replaced by EPS concrete for the in-fill and partition walls of the buildings.

“…However, these techniques might not be environmentally friendly and readily available in all countries. In addition, the reusing and recycling of waste materials in developing and less-developed countries are still in its early phases (Miled, 2004;Herki, 2017;Khatib et al, 2013). Using silica stone waste (SSW) is another waste material which can be used as a substitution for cement and contribute to a better bonding and higher mechanical properties such as compressive and tensile strength.…”

At present, most of the generated waste expanded polystyrene (EPS) in developed countries are transported to landfill and in some developing and/or less-developed countries such as Iraq are sent to open landscapes; consequently, this inadequate waste disposal can be very dangerous to our health and environment. This study describes engineering properties of sustainable lightweight aggregate concrete (LWAC) incorporating novel aggregates of waste EPS produced by a unique recycling technique of densifying. The new recycling technique significantly improved the segregation resistance of EPS beads in concrete as these beads are ultra-light material. The novel LWA of densified EPS (DEPS) was used as partial natural aggregate replacement in the mixes. Three water/cement (W/C) ratios were used. Three different types of curing conditions of indoor full water curing, outdoor weathering exposure, and heating exposure were employed during this study to represent different conditions which concrete may be subject to. The engineering properties of concrete investigated were consistency, dry density, compressive strength, and ultrasonic pulse velocity (UPV) for long-term performance of more than one-year age. It was indicated that the properties of concrete were not only primarily influenced by the employed curing conditions but the content of DEPS in the mixtures and additionally the W/C ratio had effect on the properties of concrete. However, adequate engineering properties can be achieved using an appropriate amount of DEPS with proper W/C and curing conditions.
