摘要

Since the use of low cement castable technology became extensive in the early 1990's, the application of additives for the efficient dispersion of fine and ultra-fine matrix components has become essential. Part 1 of this paper discusses the value of additives in general, and compares the differences in various traditional and modern additive concepts covering flow properties, working time, setting behaviour, and their impact on physical properties incl. hot properties in silica fume-free low cement castabies. Part 2 will be published in in the next issue rwf 4/2014 and will discuss additives used in castabies containing silica fume as fine matrix filler in the range of 3-5 % additions.
