Abstract
[Abstract:] The production of farmed mussels amounts to millions of tonnes across over 40 countries. Shell waste resulting from this production has a very significant environmental impact. In Galicia, mussel shell waste is transformed, using low impact heat treatment, into a by-product that can be used as an aggregate. This research investigates cement-coating mortars where conventional aggregate is partially replaced with mussel shell aggregate. Reference mortars and mortars with mussel shell sand replacing conventional sand at different rates: 25%, 50% and 75% have been tested. Results show the feasibility of mussel shell in cement coatings at an optimal replacement rate of 25% of the conventional aggregate.
