    • A binder mix containing a hydraulic binding agent and an admixture mixed therewith, a process for preparing a hydraulically hardened binder mass, a calcinated kaolin product and a process for preparing the same. A paste-like composition is formed from the hydraulically hardening binding agent, a pozzolanically reacting admixture and water, which, when so desired, contains stone aggregate or similar filler, the paste-like composition is worked and the worked composition is allowed to harden to form the binder mass. The admixture comprises spherical, porous metakaolin agglomerates, the size of which is 2-200 microns and which have an open pore structure. The invention can be used to improve the manufacturing methods of cast concrete products and shorten the manufacturing times, and to provide concrete with better mechanical and chemical properties, as well as improve the fire and frost resistance of concrete.
    • 含有水硬性结合剂和与其混合的混合物的粘合剂混合物,制备水硬性粘合剂组合物的方法,煅烧高岭土产品及其制备方法。 糊状组合物由水硬性结合剂,火山灰反应混合物和水形成,当需要时,水含有石料骨料或类似填料,加工糊状组合物,使加工组合物硬化 形成粘合剂物质。 该混合物包括球形,多孔的偏高岭土聚集体,其大小为2-200微米,并具有开孔结构。 本发明可用于改进铸造混凝土制品的制造方法,缩短制造时间,提供混凝土具有更好的机械和化学性能,以及提高混凝土的耐火和防冻性能。
