Sustainability-Oriented Multi-Criteria Analysis of Different Continuous Flight Auger Piles

With increasing construction activity and concrete consumption globally, the economic, environmental, social impacts of human activities continue to increase rapidly. Therefore, it is imperative assess choice each structure structural component from a sustainability-based perspective. In this study, such multi-criteria decision-making approach using MIVES method applied grouped continuous flight auger (CFA) piles. Different alternatives CFA piles are studied: length (10 20 m), reinforcement (steel cage fibers), aggregates (natural crushed recycled aggregate sourced stationary mobile recycling plants), based on experimentally verified mix designs. All were analyzed considering requirements, tree with eight criteria eleven indicators, weights assigned by an expert panel. The results analysis showed clear advantage in terms all three sustainability requirements for steel fibers concrete, solutions having significantly lower values index. Such demonstrate need implementing innovative even members as that often considered insufficient detail.
