一种无机粉体保水剂及其制备方法与应用
摘要：
本发明公开了一种无机粉体保水剂及其制备方法与应用。所述无机粉体保水剂由除氯碱渣混合物和混合材料组成。所述无机粉体保水剂的制备方法包括如下步骤：将除氯碱渣混合物和混合材料按所述质量百分比混合均匀后，加入粉磨设备中，经粉磨处理至0.30mm筛余小于10wt%的混合粉体，得到无机粉体保水剂。本发明制备的无机粉体保水剂保水性好，能够用于改善砂浆的保水性和混凝土的收缩性。
摘要（英）：

The invention discloses an inorganic powder water retaining agent and a preparation method and application thereof. The inorganic powder water retaining agent is prepared from a dechlorination alkali residue mixture and a mixed material. The preparation method of the inorganic powder water retaining agent includes the following steps that after the dechlorination alkali residue mixture and the mixed material are mixed to be uniform according to the mass percentage, the mixture is added into grinding equipment, the mixture is ground into mixed powder with 0.30mm residues on a sieve smaller than 10 wt%, and the inorganic powder water retaining agent is obtained. The prepared inorganic powder water retaining agent is good in water retaining performance, and can be used for improving the water retaining performance of mortar and shrinkage of concrete.
