Super quick setting and super high early strength cement was studied. Amount of microaggregate added in this kind of cement was up to 13%.
本实验研制的超速凝超早强水泥中的微集料掺加量高达13％。
From three aspects: morphological effect, active effect and microaggregate effect the action mechanism and application significance are described.
从形态效应，活性效应，微集料效应三个方面描述了其作用机理和应用意义。
The plant residue with more lignin has a higher humification coefficient. As the residue containing more N is more favorable to the formation of soil microaggregate.
其中含木素较多的植物残体，表现为腐殖化系数较高，含氮多的植物残体，则有利于土壤微团聚体的形成。
In the same modifier, as the increase of the using level of calcium activator, the bulk density showed a descending trend gradually and the microaggregate showed an opposite trend gradually.
