Abstract

Snail shells are the bio-shells that eateries discard. Around 100 million tonnes of snail shells are come out as waste material in the world every year. These were creating substantial environmental problems and harm to living organisms. As mentioned earlier, the present work focuses on using snail shell powder (SSP) as a raw material in mortar. The current work compared the calcined and un-calcined snail shells powder behaviour in mortar concerning mechanical and durability properties. Calcined and un-calcined snail shell mortar composite is partially replaced Cement with snail shell powder of 0–35% with a variance of 5% in mortar. The chemical composition of both the mixes was assessed by X-ray diffraction (XRD) analysis. In addition, a compressive strength, flexure and split, and tensile strength test were performed on both mixes to determine the mechanical properties of mortar. Water absorption, sorptivity, and rapid chloride permeability tests on cement mortar were done on both mixes. According to the investigation results, the best use of snail shell powder is 30% for un-calcined shells and 25% for calcined shells. The durability properties of both mixes improved when the amount of snail shell powder increased, and neither blend showed much variation. Microstructural analysis viz., XRD, SEM, and EDS has been performed on both mixes and obtained higher C–H gel and C–S–H gel formations at 25% and 30% replacement of Cement of calcined and un-calcined snail shell powder.
