(上接2015年第11期第24页)第10讲t复配技术有诀窍(之三)仝:现在我们细说第三个诀窍行吗?季:这第三是要随水泥品牌或产地不同而及时调整复配剂的碱含量和硫含量(实质是硫酸根离子含量)。这问题近年来显得特别突出,几乎多一半的混凝土流动性差、即坍扩度小以及坍落度损失快都与水泥本身可溶碱含量多少和硫酸根含量多少有关,也和这两个数值比例失当分不开。
(Continued on page 11, 2015, p. 24) Lecture 10 t know how to compound technology (third) with: Now we elaborate on the third trick? Season: This third is to follow the cement brand or Different origin and timely adjustment of compound alkali content and sulfur content (in essence, sulfate ion content). This problem is particularly prominent in recent years, almost half of the poor concrete flow, slump expansion and slump loss are almost as fast as the content of soluble alkali and the amount of sulfate itself and how much, and these two numerical ratio Misconduct can not be separated.
