STUDY ON EFFECTS OF CURING TECHNIQUES ON DURABILITY PROPERTIES OF SELF-COMPACTING CONCRETE WITH METAKAOLIN

The current trend in the construction industry is either using Self Compacting Concrete (SCC) or developing new mix proportions for the application of SCC to various structures. However, many research workers have observed that curing methods and conditions in the field affect the behavior of SCC constructions. Besides, limited knowledge about the impact of curing on the long-term durability of SCC. Consequently, it is necessary to know the behavior of SCC under several curing requirements and the influence of pozzolanic material such as metakaolin on acid and sulphate resistance test. This paper reports the outcomes of a research study accompanied to estimate the effect of curing methods on the durability properties of self-compacting concrete with metakaolin. Six types of curing compounds, namely Immersion, Hot water, Ice, Sea water, Polyethylene Film, Wet Covering and Curing compound is being applied on the concrete specimens. The results showed that Immersion curing has the least effect on acid and sulphate resistance of SCC made with metakaolin.
