“…The larger particles and their porosity do not pack as tightly as the smaller particles do. The air circulation between the porosities enhances the water holding capacity, and after imbibing water, it enlarged the pore sizes of the coir pith (Priyadarshini et al, 2021). At the point when the size of the coir essence molecule expanded, the water-holding porosity diminished which eventually expanded the air circulation porosity.…”

Aim: To evaluate the physical and hydrological properties of different graded coir pith and composted coir pith (CPOM) following the Keen-Raczkowski box and Brunauer-Emmett-Teller (BET) analysis. Methodology: The coir pith was collected and composted by PITH PLUS (Pleurotus-sajor-caju). Thereafter, the coir pith and composted coir pith were segregated into different groups based on the size of the particles as 1.0 mm (1000 microns), 0.5 mm (500 microns), and 0.25 mm (250 microns). Based on particle size, the hydrological properties of coir pith and composted coir pith were determined. The physical and hydrological properties were estimated by the Keen-Raczkowski box method and Brunauer-Emmett-Teller analysis. Results: Different graded coir pith and composted coir pith of size 0.25 mm showed the highest bulk density (0.60 and 0.48 g cm-3), followed by 0.5 mm size coir pith and composted coir pith, respectively. The highest particle density (0.18 and 0.19 g cm-3) was registered in 1.0 mm coir pith and composted coir pith whereas the lowest particle density was observed in 0.25 mm size coir pith (0.15 g cm-3). The water-holding capacity (817.93 % and 806.97 %) and water in air-dry substrate (25.03 % and 36.094 %) was high in 0.25 mm coir pith and composted coir pith. Interpretation: A 0.25 mm grade of coir pith and composted coir pith showed highest water holding and retaining capacity due to a greater number of small particles being compactly arranged and holding more surface area, and innumerable micropores than other graded particles. Key words: BET analysis, Coir pith, Composted coir pith, Water holding capacity

“…Although coconut coir has been continually utilized in cementitious composites such as concrete (Ali et al 2022), cement mortar (Sathiparan et al 2017), stabilized earth blocks (Thanushan et al 2019), surface plaster , etc., the use of cocopeat in cementitious materials is very limited. Priyadarshini et al (2021) investigate the strength of concrete featuring cocopeat as a partial replacement for sand. Results show that treated cocopeat improved the compressive strength and bonding characteristic of concrete.…”

The production of agricultural, industrial, and demolition trash increases along with global population growth and industrial expansion. They endanger the environment when they are not properly recycled, repurposed, or disposed of. Cocopeat is one such agricultural waste. The use of cocopeat in binder cement is urged to support sustainable construction methods. Because it is seen as trash and discarded in landfills. Cocopeat is an environmentally friendly by-product which can be got during the coconut fibre extraction process. The current study investigates the strength properties of masonry built with binding mortar that incorporates cocopeat as opposed to traditional cement-sand mortar. The mortar prepared with four different integrations of cocopeat as sand replacement of 0, 4, 6 and 8% by weight was used for masonry. Fresh properties of cocopeat binding mortar and their effect on the mechanical characteristics of masonry were investigated. The test results revealed that the mechanical characteristics of masonry were enhanced with increased cocopeat content in the mortar.
