Mechanical properties of mortar containing recycled Acanthocardia tuberculata seashells as aggregate partial replacement

Waste management is a most current topic, and as such, numerous articles in literature discuss over the recycling and re-use of waste materials from various fields. A common solution is the to use these materials as partial substituent of the inert fraction in concretes and mortars. This work focuse...
