Shells mussel in on cement making • Aggregate Research ...
Shells mussel in on cement making. Up to 20,000 tonnes of shells would be stored in limestone-capped stockpiles at the Cape Foulwind quarry for between four and six months.Mr Dempsey said mussel shell was almost pure calcium carbonate, a fundamental raw material for cement. It was now sourced from limestone in the quarry but mussel shells ...
Performance of mussel shell as aggregate in plain concrete ...
2.3. Concrete mixes. Two different types of concretes, a non-structural concrete (NSC) and a plain structural concrete (SC) were studied. Both of them were designed with high slump values (fluid and liquid consistencies) in order to use the highest possible mussel shell aggregate substitution percentages, predicting that the mussel shell incorporation would reduce the workability.
Performance of mussel shell as aggregate in plain concrete ...
Mussel shells were used as aggregate in the concrete strip footing (foundation) and in the exterior and interior coating mortars (walls), and as loose-fill material for the whole envelope ...
Utlisation of Mussel Shell Waste as Partial Concrete ...
The shells are a less expensive way to enhance the strength of concrete by producing a substance for the cement paste to bond. Mussel shells obtain their strength from a nacre layer that contains a crystalline structure in the type of calcium carbonate.

Design and properties of cement coating with mussel shell ...
The dosage for surface-layer coating (SC) was designed with a cement:sand ratio of 1:4 and water:cement ratio of 0.9. Mussel mortars were designed replacing conventional sand with mussel shell sand by volume. The replacement percentages used were 25%, 50% and 75%. So eight mussel shell cement mortars were obtained.

Design and properties of cement coating with mussel shell ...
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 ...
Design and properties of cement coating with mussel shell ...
Mussel shells are a by-product converted into fine aggregate after a low environmental impact process. Shell aggregate disturbs microstructure and pore size distribution of cement coatings. Particle shape and shell composition are the main characteristics affecting coating properties. The use of 25% mussel shell leads to accurate surface and ...

Performance of mussel shell as aggregate in plain concrete ...
Abstract. In this work the performance of mussel shell as aggregate in plain concrete has been studied. The mussel shell used came from the cannery industry, which produces more than 1 million tonnes of shell by-product a year worldwide. The mussel shell has been heat-treated at 135 °C for 30 min and then crushed and sieved into sand and gravel.

Two types of mixes were prepared. The first one, called "Mussel Concrete" (MC), is formulated by mass substitution of cement by MP at a rate of 6-12 and 24%. The specimens will be noted MC6, MC12, and MC24, respectively. The second mixture is called "Mussel Filler Concrete" (MFC).
