小梁干缩应变、平均干缩系数随失水率、集料级配的变化规律。
Along with percentage of water loss and aggregate grade, the laws of small beam dry shrinkage strain and average dry shrinkage index.
在整个干燥过程中，表层的自由干缩应变最大，越靠近芯层自由干缩应变越小。
Throughout the drying process, the surface of the free shrinkage strain is the largest, the more close to the core layer the smaller the free shrinkage strain.
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。
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.
