Preliminary investigations of essential oils as corrosion inhibitors in steel reinforced cementitious systems
Encapsulating bioactive agents in lightweight aggregate (LWA) is a method that shows promise as a corrosion mitigation technique in cementitious systems. LWA aggregates acts as a storage unit for the bioactive agent. Once hydration reactions in the cementitious matrix cause a drop in the internal humidity, the LWA will achieve pressure equilibrium by releasing the bioactive agent. In this way the bioactive agents, which normally severely retard hydration, will not interfere with the early age property development of the cementitious matrix. Desorption, compressive strength and calorimetric tests were conducted. It was found that expanded clay LWA absorbed more cinnamaldehyde than pumice LWA, however, the incorporation of bioactive agents severely retarded hydration and reduced the composite's strength. Significant future work that is needed, including microscopic studies, are discussed.
