“…The improvement in the tensile strength could be due to the greater contact surface area amongst WCMF fibres and the binder paste. It could be attributed to the higher pozzolanic hydration products, which is in line owing to the good pozzolanic nature of POFA at the ultimate ages [34]. Figure 9 demonstrates the obtained results of flexural strength test.…”

The consumption of waste materials is one of the essential concerns of waste management strategies in many parts of the world. With the advances in concrete technology, the utilisation of waste materials in the sustainable construction has developed increasingly widespread because of technological, economic and ecological advantages. This paper presents the workability and mechanical properties of concrete incorporating waste chopped metallic film (WCMF) fibres and palm oil fuel ash (POFA). Waste plastic results in waste discarding disaster and consequently causes significant harms to the environment. WCMF fibres were prepared by recycling metallic-plastic films used for food packaging. Six concrete mixes containing 0-1.25% WCMF fibres with a length of 20 mm were made of ordinary Portland cement (OPC). Further, six concrete mixes with the same fibre content were made, where 20% POFA substituted OPC. The combination of WCMF fibres and POFA decreased the workability of concrete mixes. The inclusion of WCMF fibres to OPC and POFA concrete mixes decreased the compressive strength. However, at the curing period of 91 days, the POFA-based mixes obtained higher compressive strength values than those of OPC-based mixtures. The positive interaction between WCMF fibres and POFA consequently enhanced the flexural and tensile strengths, impact resistance, thereby increasing energy absorption capacity and ductility of concrete composites. It revealed that WCMF fibres acted as a bridge arrester and improved the load-transfer capacity of the concrete specimens. The study showed that the utilisation of WCMF fibres in the production of sustainable concrete is a beneficial, affordable and feasible solution. Keywords. Sustainability; fibre-reinforced concrete; waste chopped metallic film fibres; palm oil fuel ash; workability; mechanical properties.

“…For the 70% FA/30% cement combination, the outcome was greater than that for the 100% FA which may have been due to the discrepancy in their air voids. Also, it has been found by different agencies that the results of immersion compression tests vary greatly and usually do not produce the actual results but present a considerable retained stability value which could be incorporated to resist moisture susceptibility [14,15]. …”

ABSTRACT:The main objective of this study was to investigate the potential of using fly ash as a mineral filler in asphalt mixtures to reduce the amount of fly ash generated from coal-based power plants in Bangladesh requiring disposal. To achieve this, several mix designs which included fly ash were developed and compared with mixtures using cement as a mineral filler, with mixtures of cement and fly ash with different ratios considered and their performances evaluated. It was found that the design with a bitumen content and fly ash as a mineral filler was within the economical range and, when its Marshall stability and flow values were compared with those of cement, it was found to be satisfactory. Also, the moisture susceptibility of an asphalt mixture with fly ash was checked through immersion-compression tests and compared with that of one with cement as a mineral filler. As it was observed that fly ash generated from coal-fired power plants can reduce the damage caused to asphalt by moisture and is more cost-effective than conventional fillers, it is proposed that using it as a filler material in pavements could reduce the substantial damage suffered by the environment.

“…From the sustainability point of view, reduction in the utilisation of non-renewable raw materials is a critical factor in sustainable construction. Sustainability helps the environment by minimising the waste materials and the reduction of raw materials consumption [1,2]. With the generation of massive amounts of wastes, several types of non-biodegradable wastes such as plastics will remain in the environment for hundreds, perhaps thousands of years [3][4][5].…”

The utilisation of industrial waste in the production of sustainable construction materials has attracted much attention recently due to the saving of vital places for landfills, low-cost of waste materials and also an improvement in the concrete properties. Exposing concrete structures to elevated temperatures causes progressive failure of the macro-and micro-structures of cement paste and, therefore, severe deterioration and damages in the load-bearing capacity. This study explored the effect of waste metalized plastic (WMP) fibres and palm oil fuel ash (POFA) on the performance of concrete exposed to high temperatures of 200, 400, 600 and 800 °C. Four concrete mixes comprising 0 and 0.5% WMP fibres, and 0 and 20% POFA content were cast. Properties studied include mass loss, compressive strength, and ultrasonic pulse velocity. The results showed that the adding of WMP fibre to the concrete mixes significantly improves the concrete performance at elevated temperatures with the lower rate of strength loss along with eliminating the explosive spalling behaviour as compared to those of plain concrete mixes. Furthermore, in comparing the results of compressive strength losses at a high temperature of 800 °C, strength losses were lower for specimens containing 0.5% WMP fibres than those of plain specimens. Moreover, green concrete decreases waste materials, the diminution of harmful impacts on the environment, and leads to sustainable and green cement and concrete industries.
