“…In comparison to the values of reference concrete, the reduction in UPV ranged from 9.3 to 34.4%, 10.5 to 47.6% and 11.9 to 48.7% for the PVC, PP and PE concrete mixes, respectively. Furthermore, the utilization of discarded plastic particles improved the acoustic qualities (Belmokaddem et al 2020 ). The rheological, mechanical and durability properties of self-compacting concrete (SCC) were examined using waste polyethylene terephthalate (PET) particles and pozzolanic ingredients.…”

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.

“…This is due to the strong interlayer bonding of their tetrahedral and octahedral sheets (Van Der Waals forces for kaolinite and potassium ions (K + ) for illite), preventing water absorption and swelling of clay. This suggests that this soil tend to have good mechanical characteristics [28,29].…”

The present work investigates the effect of using olive pomace bottom ash, the by-product of the clay brick industry, as an additive in the manufacture of fired clay bricks. Furthermore, it aims to improve the properties of clay bricks by using naturally available materials and also to develop an innovative way of recycling the waste resulting from the brick firing process. Olive pomace bottom ash was added to clay with multiple proportions (0%, 5%, 10%, 15%, and 20%) by weight. Bricks were molded by compression at 6.5 MPa, using a hydraulic brick press machine, and fired in an industrial scale furnace. The physicochemical, mineral, and geotechnical properties of raw materials were identified to study raw materials' effect on the final fired products' performance. The quality of fired specimens was determined by bulk density, linear shrinkage, water absorption, porosity, compressive strength, and thermal conductivity. In fact, samples with 5% olive pomace ash represent the highest compressive strength level, 11.5 MPa, compared to 9.65 MPa of reference samples. On the other hand, additions up to 20% increase the brick sample's porosity from 18.28% to 34% for the reference mixture and the brick incorporated with 20% of additive, respectively, and decrease the brick's bulk density from 1522 kg/m 3 to 1431 kg/m 3 for the reference mixture and the brick incorporated with 20% of additive, respectively. The incorporation of ash also improves the thermal conductivity of brick specimens. Expressly, thermal conductivity went from 0.41 W/m.K to 0.33 W/m.K for the reference mixture and the brick incorporated with 20% of additive, respectively, showing 37% of gain in thermal insulating properties of brick. Unfortunately, the capillary water absorption coefficient increases to 28% when 20% of additive is incorporated, which is not desired in the properties of construction materials. ASTMC67-07a standards: 2003, recommend water absorption level less than 17% for bricks with moderate weathering resistance. It was concluded that the addition of olive pomace bottom ash should not exceed 10% since it can be helpful in fired clay brick production based on standards requirements, leading to remarkable ecological gains without a loss of brick's performances.

“…These practices have shown potential to ameliorate the incidence of poor waste management through the introduction of efficient material handling regimes that support material recovery, recycling, and reuse for the housebuilding subsector. The extant literature is replete with reportage of cases wherein PET waste has been used: for substituting aggregates in the concrete mixture [ 20 ], improving the thermal response of unfired lightweight clay bricks with the aid of high-density polyethylene (HDPE) plastic waste [ 21 ], as aggregate replacement in blocks (plastic aggregate blocks, for the construction of (flexible) pavements [ 22 , 23 ], and as aggregate replacement in asphalt concrete mixture [ 24 ]. Similarly, scholars have elucidated instances wherein WFS has been utilized for the development of green-efficient masonry bricks based on a mixture of scrap plastic waste (SPW) [ 15 ], for the production of sustainable bricks, blocks, and paving stones.…”

Durability Assessment and Microstructure of High-Strength Performance Bricks Produced from PET Waste and Foundry Sand

et al. 2021

Fired clay brickwork in buildings is prone to cracks and deterioration upon exposure to long-time acidic contamination and water absorption, hence decreasing the bearing capacity of masonry walls. As its contribution toward resolving this challenge, this study assessed the durability and morphological characteristics of high-strength performance bricks produced from a mixture of PET waste (PW) and foundry sand (FS). The PET waste bricks (PWBs) were produced through different proportioning (PW: FS) of 20%, 30%, and 40% of the dry mass of FS. The PWBs produced were tested for durability and compressive and tensile strengths and compared to fired clay bricks to evaluate their load-bearing capacity under compression and tension. Furthermore, scanning electron microscopy (SEM) tests were employed to analyze the morphological structure of the bricks. The test results revealed that the PWBs recorded an appreciable strength of 1.5–2 times that of fired clay bricks, and lower water absorption whilst retaining their ultimate strengths after complete immersion in water and acidic concentrations. The morphology of PWB possessed greater intercluster bonds on the surface compared to clay bricks. The findings demonstrate a reasonable methodological approach toward the production of masonry bricks using a mixture of PET waste and spent foundry sands.
