Investigation of Mechanical and Thermal Performance of Concrete with Scallop Shells as Partial Cement Replacement: Alternative Binder and Life Cycle Assessment

The adverse environmental impacts of building materials can be achieved by reducing the amount cement in cementitious composites, specifically when incorporating wastes as partial replacement for Portland cement. In this work, we substitute with shell by-products while keeping useful specific properties. Scallop shells are good candidates to replace part they contain calcium and available abundance. We present an experimental numerical study on mechanics, hygrothermal behavior, life cycle analysis scallop concrete. fresh state, up 10 wt.% does not significantly affect mortar results indicate that including 10% represents a decrease 40% impact, depending category impact considered. Furthermore, addition makes material more porous, leading facilitation moisture transfer.
