Environmental Sustainability and Engineering Performance of Self-Compacting Mortar Incorporating Fly Ashes

Abstract:

This paper investigated the effect of fly-ash on environmental sustainability and engineering performance of mortar. Samples of mortar were prepared with different dosage of superplasticizer to gives three ranges of workability that is normal slump flow, high slump flow and self-compacting flow. Cement content of 550 kg/m³, water/binder ratio of 0.35, binder/cement ratio of 2.00 and fly ash replacement 10%,20%, 40%, and 60% were adopted for the mix proportion.The relationship to look into are the potential of CO2 reduction in the mortar mixes while cement content were replace by fly ash. Results showed that self-compacting mixes with 20 % replacement by fly ash provides an increase in 28 day strength, enhancing the durability with low % of water absorption and reducing the environmental impact with low CO2 footprint. This gives it the best balance of durability and environmental sustainability impact of the mixes.
