Design and properties of cement coating with mussel shell fine aggregate
[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. ; This work has been carried out within the framework of the project “Valorización de las conchas de bivalvos gallegos en el ámbito de la construcción” (Assessment of Galician bivalve shell in the construction sector; Code 00064742 / ITC-20133094), funded by CDTI (Centro para el Desarrollo Tecnológico e Industrial) under the FEDER-Innterconecta Program, and co-financed with European Union ERDF funds. We wish to express our most sincere thanks to the professionals of the firms Extraco, Serumano and Galaicontrol. ; Centro para el Desarrollo Tecnológico e Industrial; 00064742 / ITC-20133094
