    • A hydraulic composition is provided. This composition exhibits an improved workability in its coating with a trowel, and accordingly, an improved working efficiency with no adverse effects on its physical properties. The hydraulic composition comprises at least one surfactant selected from anionic surfactants having foaming ability (group A), at least one surfactant selected from surfactants which are nonionic antifoaming agents (group B), and a water-soluble cellulose ether. The surfactants of group A and group B are respectively added at 0.000005 to 0.004% by weight (solid content) in relation to the powder ingredients in the hydraulic composition, and the water-soluble cellulose ether is added at 0.02 to 1.2% by weight of the hydraulic composition.
    • 提供水硬性组合物。 该组合物在用t刀涂料中表现出改进的可加工性,因此提高了工作效率,对其物理性质没有不利影响。 水硬性组合物包含至少一种选自具有发泡性的阴离子表面活性剂(A组),至少一种选自非离子消泡剂(B组)的表面活性剂和水溶性纤维素醚的表面活性剂的表面活性剂。 相对于水硬性组合物中的粉末成分,A组和B组的表面活性剂分别以0.000005〜0.004重量%(固体含量)添加,水溶性纤维素醚以0.02〜1.2重量% 水硬组合物。
