Abstract
Curing of concrete is maintaining
satisfactory moisture content in concrete during its
early stages in order to develop the desired
properties. Any laxity in curing will badly affect the
strength and durability of concrete. The aim of the
investigation is to evaluate the use of water-soluble
polyethylene glycol as self-curing agent with partial
replacement of conventional fine aggregate with
light weight fine aggregate such as sand stone and
to optimise the quantity of lightweight aggregate and
poly-ethylene glycol. By studying the mechanical
properties of concrete by replacing the fine
aggregate with lightweight fine aggregate by 0%,
10%, 20%, 30%, 40% and 50%, the optimum
quantity of lightweight aggregate was found as 25%.
Self-curing concrete of M30 grade were cast by
replacing fine aggregate with 25% lightweight fine
aggregate, whose water absorption property is high,
and by varying quantity of polymeric glycol by 0.5%,
1%, 1.5% and 2%, the optimum percentage of
polyethylene glycol was found as 1%. In this study,
compressive strength, split tensile strength of selfcuring
concrete with varying quantity of
polyethylene glycol was evaluated and compared
with the conventional concrete specimens.
