Description
Poliana Bellei and four co-authors turn oyster shell waste into building material in this two thousand twenty-five paper. Piles of discarded shells are a disposal problem in coastal areas. Lime mortars, used on old brick buildings, may take shell as an ingredient. The team made mortars with natural hydraulic lime. In one mix, shell powder replaced part of the lime. In another, crushed shell replaced part of the sand.
They tested the mortars in molds and spread on solid bricks like those in historic walls. Heat and humidity cycles mimicked aging. The shell mixes were then compared with a plain control mortar. The authors report on strength, physical traits, and durability. The work points to greener repair materials for heritage buildings.
