Performance of mussel shell as aggregate in plain concrete

摘要

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 degrees C for 30 min and then crushed and sieved into sand and gravel. The new aggregates have been studied by X-ray diffraction (XRD), TGA and SEM microscopy.
