Last, the temperature contraction coefficient and dry shrinkage coefficient of porous concrete are advanced.
得出多孔混凝土的温缩系数和干缩系数。
It was shown that dry shrinkage and shrinkage coefficient of specimens decreased if partial cement was replaced by fly ash and slag, and then further by more fly ash.
结果表明，用矿渣和粉煤灰取代部分水泥，随后又增加粉煤灰的比例，可以连续降低固化土的干缩应变和干缩系数。
