Curing Concrete

Curing Concrete


“holding water in the concrete”



Will:
- Increase concrete strength
- Increase concrete abrasion resistance
- Lessen the chance of concrete scaling
- Lessen the chance of surface dusting
- Lessen the chance of concrete cracking


CURING DEFINED
Curing can be defined as a procedure for insuring the hydration of the portland
cement in newly-placed concrete. It generally implies control of moisture loss and
sometimes of temperature. The hydration of portland cement is the chemical reaction
between grains of portland cement and water to form the hydration product, cement gel:
and cement gel can be laid down only in water-filled space. Hydration can proceed until all
the cement reaches its maximum degree of hydration, or until all the space available for the
hydration product is filled by cement gel, whichever limit is reached first.


Water curing -is
when the
concrete is
covered with a
layer of water for
a period of time
and the
evaporation of
moisture is from
the surface of the
water.


The curing of the concrete is dependent on the quality of the film, the thickness, and
the uniformity of the film applied to the concrete. The curing membrane used is the least
expensive component in the completion of quality concrete construction, and the most over
looked.
