Ecological Footprint and Economic Assessment of Ready-Mix Concrete Production
Cement industries constitute approximately 8% of global anthropogenic carbon dioxide emissions, including cement by-pass dust, making them a critical environmental concern due to their direct impact on human health and global warming. Typically, conventional concrete production utilises cement as a binding material. On the contrary, the present study addresses this critical issue by using Fly ash and GGBS (Ground granulated blast-furnace slag) to partly replace cement in M20, M25, and M30 grades concretes. The present work evaluates the environmental impact of concrete production with supplementary cementitious material for normal concrete using the Ecological Footprint (EF) tool for ready-mixed concrete (RMC) plants. The results showed that the fly ash and GGBS can effectively replace cement in conventional concrete, with meet the target comparable compressive strength. The annual Ecological Footprint of the ready-mix concrete (RMC) plant is estimated as 919.05 gha. Using Fly ash and GGBS in concrete production can be an innovative solution because it simultaneously solves the problem of solid waste disposal, carbon emissions, cost and environmental impact.
