Potential of sugarcane bagasse ash as supplementary cementitious material and comparison with currently used rice husk ash

Use of bagasse ash in the cement industry is hindered due to a lack of comprehensive information on its influence on concrete. Moreover, a comparison of the potential of bagasse ash with a well-known agricultural by-product, rice husk ash will increase the chance of its acceptance. Hence, physical, chemical, and morphological characteristics of bagasse ash are compared with rice husk ash. Strength of bagasse ash blended concrete, and rice husk ash blended concrete is higher than the control concrete up to 20% and 15% of cement replacement levels, respectively. Significant resistance against chloride, water, and air permeability was witnessed for bagasse ash, or rice husk ash blended concrete up to their optimum replacement levels. (C) 2020 Elsevier Ltd.

Automated summary

The use of bagasse ash in the cement industry is hindered by a lack of information on its influence on concrete, but its blended concrete shows higher strength than control concrete at certain levels of cement replacement. Bagasse ash or rice husk ash blended concrete exhibits significant resistance against chloride, water, and air permeability at their optimum replacement levels.
