Abstract: This paper is aimed to utilize the benefits of Self-curing compound in high strength (M60) Selfcompacting concrete. A Self-curing compound is provided to absorb water from atmosphere to achieve better hydration of cement in SCC without submerging into water. Self-curing compound is Polyethylene glycol of molecular weight 600 (PEG-600) of dosages ranging between0.1 to 2 by weight of cement added to mixing water. SCC is characterized by its fresh properties like flowability, filling ability and resistance to segregation and bleeding are done by slump flow, J-ring, V-funnel, L-box and U-box tests on SCC to satisfy EFNARC specifications. Whereas hardened properties like compressive strength is tested at 7, 14, 21 & 28 days, tensile and flexural strengths are tested after 28 days of curing. An attempt has been made in the investigation reported in this project to study mechanical properties like Compressive strength, Tensile strength and Flexural strength of High strength SCC in the presence of Self-curing compound. There may be an improvement in the mechanical properties of High strength SCC with Self-curing compound are observed and compared with High strength SCC without Self-curing compound. This paper confirms that specimens with 0.5 of PEG achieved better mechanical properties.
