Abstract
As water is becoming a scarce material day-by-day, there is an urgent need to do research
work pertaining to saving of water in making concrete and in constructions. Curing of
concrete is maintaining satisfactory moisture content in concrete during its early stages in
order to develop the desired properties. However, good curing is not always practical in many
cases. Curing of concrete plays a major role in developing the concrete microstructure and
pore structure and hence improves its durability and performance. Keeping importance to
this, an attempt has been made to develop internal-curing concrete by using Poly Ethylene
Glycol (PEG-400). In this experimental investigation the strength characteristics of Normal
Strength Concrete and high strength concrete, cast with the self-curing agent PEG-400 have
been studied and compared with the corresponding conventionally cured concrete. IS method
of mix design was adopted, for the normal strength internal curing concrete of grade M20 and
for M50 grade of concrete is design on trial and error basis. For producing internal-curing
concrete trial dosage of 1%, 2% and 3% of PEG-400 by weight of cement was used and
tested. It was observed that after implementation of new technique the water consumption for
curing was significantly reduced by 100%.
