Utilization of Mesua Ferrea Seed Shell Ash (MFSSA) as Pozzolanic Material by Partial Replacement to Cement in Mortar

The sustainable and eco-friendly construction materials have sparked research into various additives that can enhance mortar properties without harming the environment. This study aims to explore the potential of Mesua Ferrea Seed Shell Ash (MFSSA) as a pozzolanic material by exhaustively characterizing its chemical, physical and mechanical properties. Studies were done to assess the influence of MFSSA content on the consistency and initial setting time of cement. MFSSA to regular Portland cement with proportions equal to 0%,2.5%,5%,7.5%, and 10% were by weight of the cement. The main question is what the influence on mortar was from the replacement of it by a new hydraulic and sand cement material. After 3, 7, and 28 days of curing, compressive strength tests were performed, thereby providing knowledge about its load-bearing ability during construction and life of the structure. The durability of the material was evaluated for periods of curing up to 56 days using a sodium sulphate resistance test. As the ratio of MFSSA was increased, consistency and setting times also improved. 3 days of curing: Conventional mortar with replacement 2.5% increased compressive strength from 23 kN/mm2 to 25 kN/mm2 . It was also obtained that compressive strength and durability towards sodium sulphate also decreased as the level of MFSSA was raised. Sustainability in construction is being advocated in this study as a whole. This study not only explored the novel use of MFSSA as a pozzolanic substance but also contributed to understanding its potential impact on blended cement properties.
