Concrete is an essential building material which is
\r\nwidely used in construction industry all over the world due to its
\r\ncompressible strength. Curing of concrete plays a vital role in
\r\ndurability and other performance necessities. Improper curing can
\r\naffect the concrete performance and durability easily. When areas
\r\nlike scarcity of water, structures is not accessible by humans external
\r\ncuring cannot be performed, so we opt for internal curing. Internal
\r\ncuring (or) self curing plays a major role in developing the concrete
\r\npore structure and microstructure. The concept of internal curing is to
\r\nenhance the hydration process to maintain the temperature uniformly.
\r\nThe evaporation of water in the concrete is reduced by self curing
\r\nagent (Super Absorbing Polymer – SAP) there by increasing the
\r\nwater retention capacity of the concrete. The research work was
\r\ncarried out to reduce water, which is prime material used for concrete
\r\nin the construction industry. Concrete curing plays a major role in
\r\ndeveloping hydration process. Concept of self curing will reduce the
\r\nevaporation of water from concrete. Self curing will increase water
\r\nretention capacity as compared to the conventional concrete. Proper
\r\nself curing (or) internal curing increases the strength, durability and
\r\nperformance of concrete. Super absorbing Polymer (SAP) used as
\r\ninternal curing agent. In this study 0.2% to 0.4% of SAP was varied
\r\nin different grade of high strength concrete. In the experiment
\r\nreplacement of cement by silica fumes with 5%, 10% and 15% are
\r\nstudied. It is found that replacement of silica fumes by 10 % gives
\r\nmore strength and durability when compared to others.<\/p>\r\n","references":"[1] H. Abdul Razak and H.S.
