concrete moisture content and
temperature, after placing and finishing have been completed, to obtain
desired concrete properties. Curing methods such as ponding or
immersion, spraying or fogging,
and saturated wet coverings, maintain the presence of mixed water in
concrete during the early hardening period. Covering the concrete with
impervious paper or plastic sheets, or by applying membrane forming
curing compounds, prevent loss of mixing water from the concrete by
sealing the surface. Live steam, heating coils, or electrically heated
forms or pads, accelerate strength gain by supplying heat and
moisture to the concrete.
