摘要: Dry mixt. (I) for the prepn. of hydromechanically transportable building material suspensions comprises: (A) 10-80 (pref. 20-40) wt. pts. hydraulic binder based on cement clinker; (B) pref. (40-70) filter ash carbon firing; (C) 1-20 (5-12) swellable clays; (D) 0.1-1 (0.2-0.5) setting retarder; (E) 0.1-2 (0.2-1.0) flowing agent; whereby amounts A, B and C used allow resulting slurry to remain at least 24 h without sedimenting or setting. Also claimed are: (i) long-term stable (II) contg. mixed with water a water/solid-value 0.25-1 0.3-0.4; (ii) an underground by mixing solidification accelerator ratio (D): is 1:2-1:6. contains hydroxycarboxylic acids their alkali salts gluconic acid sodium gluconate. comprises high molecular sulphonated substances ligninsulphonate naphthalin- melamine-formaldehyde condensate sulphonate. The fineness 2000 above 3500 cm2/g (Blaine). USE/ADVANTAGE - in mfr. (II). It up 30degC
