The hydraulic drive motors keep the XD pulling lowslumpconcrete and riding smoothly over chaired rebar and other obstacles.
液压驱动马达保持了XD拉低低迷具体主持骑顺利,钢筋和其他障碍。

It has high water reducing rate at low dosage whether the adaptability problem with cement and high slump loss are always the point in concrete production.
它具有掺量低、减水率高的优点,但与水泥适应性较差和坍落度损失大一直是混凝土生产上的难题。
