本发明粉煤灰掺加量高、抗压强度高、干燥收缩值低、耐久性较好。
The method of the invention has advantages of high content fly ash and compressive strength, low drying shrinkage value and good durability.
延长混凝土的早期水养时间，并不会减少混凝土的干燥收缩值，反而会使干缩速率加快；
The early water curing of concrete is longer and then the rate of late drying shrinkage of concrete is faster.
