Abstract
In order to obtain good quality concrete, the placing of any mix must
be followed by curing. Curing prevents water evaporation from concrete or
at least reduces it in order to provide sufficient water for continuous cement
hydration and consequently the achievement of the concrete strength
together with good quality. In this study, the self-curing agent which is the
latest development in this track is the point of emphasis.
The experimental program includes two stages. In Stage (I), the
properties of fresh concrete (slump retention and air content) and hardened
concrete (water retention, unit weight, strength, sorptiviry, absorption,
permeability, carbonation and shrinkage) were determined for conventional
concrete mixtures with different curing regimes. Stage (II), is similar to
stage (1) but for self-curing concrete mixtures.
from the analysis and discussion of the test results obtained in the
research, it can be concluded that continuous moist curing is the best
method to maintain good quality concrete. Self-curing concrete has the best
properties compared with air curing in both normal and hot weather. Partial
moist curing in the early age for self-curing concrete has an obvious
improving for self -curing concrete properties.
