Sea shells used as partial aggregate replacement in concrete

· – The purpose of this paper is to examine the use of a waste marine sea shell product incorporated into a concrete mix as an aggregate replacement. Utilising shells reduces the storage of shell waste, also reducing the need for quarried aggregate and has potential benefits of adding a different material to a design mix concrete mix design for improved .

Recycled Aggregates

The concrete itself becomes aggregate and any embedded metals can be removed and recycled as well. As space for landfills becomes premium, this not only helps reduce the need for landfills, but also reduces the economic impact of the project. Moreover, using recycled concrete aggregates reduces the need for aggregates. This in turn ...

Partial Replacement of Coarse Aggregate with Broken Ceramic

replacement varied from 0% to 40% at intervals of 5%. The slump test was used to assess the workability of the fresh concrete. The compressive strengths and densities of cured concrete cubes of sizes 150mm x 150mm x 150mm were evaluated at 7days, 21days and 28days. A total of 81 concrete cubes were cast and tested.
