Curing plays an important role on strength development and durability of concrete. Curing takes place immediately after concrete placing and finishing, and involves maintenance of desired moisture and temperature conditions, both at depth and near the surface, for extended periods of time. Properly cured concrete has an adequate amount of moisture for continued hydration and development of strength, volume stability, resistance to freezing and thawing, and abrasion and scaling resistance.

The length of adequate curing time is dependent on the following factors:
Mixture proportions
Specified strength
Size and shape of concrete member
Ambient weather conditions
Future exposure conditions

热胀冷缩知道吧。。。
简单说就是防裂，加速固化。。。

调节温度和湿度，使混凝土硬化的化学反应不要太快或太慢，并使混凝土表面获得足够水份，结构比较紧密。
