“…Yunusa [46] observed decreased workability with increased CCW content proportion in concrete. The Compacting factor values can be categorised as low (0.85) in the values that fall within the medium range of slump (35mm -75mm) following BS 1881.…”

As environmental concerns gain prominence worldwide, the significance of sustainable building practices cannot be understated. The burgeoning production of waste annually exacerbates these concerns, with projections indicating a likely increase in volume and corresponding environmental pollution. This review study offers a sustainable approach to address this issue by exploring the potential of waste materials, namely, calcium carbide waste (CCW), crumb rubber (CR), and fly ash (FA), in the redevelopment of Self-Compacting Concrete (SCC). A comprehensive literature review was undertaken, encompassing several key areas: the properties of SCC, the influence of CCW on concrete workability, setting and strength (compressive, tensile, and flexural), and the characteristics of SCC incorporating crumb rubber. A detailed examination of design methodologies for SCC was conducted, including the Japanese design method, the European guidelines for SCC mixed design approach, and the mixed design according to BS EN 206:2013. Acceptance criteria for SCC set by various institutions were also evaluated, along with the composition and classification of rubber aggregates. Findings from the review suggest that CCW is a viable partial substitute for cement and cementitious materials in SCC. The consistency, along with the initial and final setting times of cement, exhibited an increase with the inclusion of FA and CCW. It is recommended that future studies consider up to a 50% FA content to produce grade 40 High Volume Fly Ash Self-Compacting Concrete (HVFA-SCC) with CCW and crumb rubber. This approach not only advances sustainable building practices but also proposes a novel solution for waste management.

“…The cement industry contributes about 7% to global warming due to the raw materials used and the manufacturing process. The carbon iv oxide (CO2) emitted during cement production for example, is a major contributor to greenhouse gases which depletes the ozone layer [5][6][7][8]. This has necessitated research into greener, eco-friendly and sustainable alternatives that can be used as building materials.…”

The rising need for affordable and eco-friendly housing occasioned by a surge in global population growth, the ever-increasing cost of building materials and environmental concerns has been an issue of concern over the last few decades. This has necessitated continuous research and development of affordable and eco-friendly building materials for low- and middle-income earners. This research evaluated the effect of oil palm fibre on the compressive strength of compressed earth blocks. Oil palm fibre was added to the soil matrix at 0%, 0.5%, 1% and 1.5% by weight of laterite. The blocks were cured for 28 days after which they were tested. The results obtained indicate that the addition of palm fibre up to 1% in the matrix increased the compressive strength to a maximum of 1.38N/mm2. Further addition of palm fibre in the matrix resulted in a decrease of the compressive strength. An optimum reinforcement of the blocks with 1% palm fibre is recommended.
