Advances in Materials Science and Engineering

As a result, the use of pulverized oyster shells as concrete additive or cement replacement often needs to be combined with other bonding materials, such as fly ash or slag . Only the Pozzolanic reaction between SiO 2 in the fly ash or slag and CaO in the pulverized oyster shells, along with the addition of water reducer or superplasticizer, can improve the strength of pulverizedoystershelladded concrete.

Innovative Systems Design and Engineering

This research focussed on the utilisation of coconut shell ash for stabilising of lateritic soil for highway pavement construction. The lateritic soil was treated with 3 to 12% coconut shell ash (CSA) to assess its effect as a soil stabilising admixture on the geotechnical properties of the lateritic soil while the soil with 0% CSA is the control.
