Recycling oyster shell waste as a bio-derived pore-promoting additive for porous phosphate-based geopolymers produced from volcanic slag
Steve Keyrane Kuida Tchikapa, Priscilla S. Brunetto, Antoine Scalabre, Placide Desiré Belibi Belibi, Katharina M. Fromm, Julius Ndi Nsami, Antoine ElimbiCalcined oyster shells promote pore development associated with calcium phosphate formation. At 5 wt% COS, a homogeneous porous structure is achieved while largely preserving compressive strength.
