Study on Carbonation Initiated by Organics in Traditional Lime Mortar
Abstract The contribution of the research is to study carbonation process of shell lime mortar on addition of organics. Lime mortar of binder to aggregate ratio 1:3 with addition of Kadukkai (Terminalia Chebula), Jaggery (Unrefined sugar) and combined Kadukkai and Jaggery, in an amount of 1 kg, 3 kg and 0.5 kg + 1.5 kg respectively per 10 L of water have been used, where the influence of organics towards development of strength and durability is well identified to suggest the use in lime construction. Traditional phenolphthalein test was conducted to measure the carbonation depth and thermo gravimetric analysis with differential thermal analysis (TGA-DTA) was used to verify the degree of carbonation and carbonation profile of lime mortar specimen. On fermentation, the organics reduce to carbon-di-oxide within the mortar, altering the hydrated phases and also resulting in more formation of load bearing forms of calcite (calcium carbonate). XRD results interpret the hydrated phases such as Calcite, Calcium-Silicate-Hydrate (CSH) and Calcium-Aluminate-Hydrate (CAH) of the organic modified mortars under carbonation and it is in confirmation with TGA.
