Three different binders have been used to study the influence of mussel shell sand: cement, aerial lime paste and clay. The cement binder has been used because it is the most use done in conventional construction. On the other hand, lime and clay have been used because they are in accordance with bio-construction principles. Reference mortars and mortars with mussel shell sand as a substitute of conventional sand in different rates: 25%, 50%, 75% and 100%, have been tested. Results show that the use of mussel shell sand increases consistency and reduces compressive strength. These effects are more remarkable as higher the substitution rate is. ER -
