Last, the temperature contraction coefficient and dry shrinkagecoefficient of porous concrete are advanced.
得出多孔混凝土的温缩系数和干缩系数。
2
The max temperature shrinkagecoefficient 28 days and 60 days is smaller than common lime-fly ash aggregate.
聚丙烯纤维加固二灰碎石的28天及60天的最大温缩系数均小于素二灰碎石的温缩系数。

It was shown that dry shrinkage and shrinkagecoefficient of specimens decreased if partial cement was replaced by fly ash and slag, and then further by more fly ash.
