Using Pozzolanic Materials to Improve Mechanical Properties of Lime‐Based Mortar
Journal of Chemistry, Volume 2026, Issue 1, 2026.The environmental impact associated with the production of Portland cement has intensified interest in sustainable alternatives such as lime‐based binders. However, their application is constrained by low early strength and slow hardening. This study evaluates rice husk ash (RHA) and sugarcane bagasse ash (SCBA) as pozzolanic additives to enhance the ...
