Microstructure and chemical resistant properties of resorcinol formaldehyde resin sand cement concrete
Resorcinol - formaldehyde resin (RF), the phenolic resin chosen for the preparation of the polymer sand cement composites is characterised by its high heat and chemical resistance. It also combines the advantage of being cost effective and crosslinking without the help of external agents that could have adverse effect on the properties of the cement concrete. The following study focuses on the changes in the microstructure and chemical resistance properties of the resorcinol formaldehyde resin cement sand composite with varying proportions of sand and cement. It was found from the study that the in situ synthesis of the resin facilitated easy mixing of the components during preparation of the composite. Investigations into the microstructure and chemical resistant properties of the composite were done after immersion of the hydrated and cross-linked polymer cement composites in different chemical environments. The compressive strength and chemical resistance properties of the composites were found to be better than those of cement concrete. The SEM revealed a more compact structure in case of the RF cement concrete and RF sand cement mortars.
