Abstract
Abstract Concrete comprises binder containing 3 to 12% of an aluminous cement having little free lime, from 4.56 to 9.73% of a phyllite clay having a base-exchange capacity of at most 10 milliequivalents per 100 grams and a flake-like structure consisting of at most two layers so that when water is added the mixture flows according to Newton''s laws instead of Binghams''s equation. The percentages given are based on the total weight of the concrete.

Claim 1
Independent Claim
128 words
A BINDER COMBINED WITH COMBINED REFRACTORY AGGREGATE AND WATER TO FORM A SETTABLE REFRACTORY MIX CONSISTING ESSENTIALLY OF SAID BINDER, AGGREGATE AND WATER, WITH THE INITIAL QUANTITY OF WATER BEING SUBSTANTIALLY EQUAL TO 6-10% OF THE FINAL WEIGHT OF THE MIX AFTER SETTING, AND SAID BINDER COMPRISING FROM 3-12% BY WEIGHT OF ALUMINOUS CEMENT, BASED ON SAID FINAL WEIGHT OF SAID MIX, FROM 4,56 TO 9.73% BY WEIGHT OF SAID CLAY AND 0.04-0.91% OF SAID DEFLOCCULATING AGEN, AND THE CLAY IN SAID BINDER CONSISTING ESSENTIALLY OF AT LEAST THE PHYLLITE CLAY SELECTED FROM THE KAOLINITE GROUP, HAVE A FLAKE-LIKE STRUCTURE COMPRISING A MIXIMUM OF TWO LYER SO AS TO HAVE MINIMAL EXPANSIBILITY, AND HAVING A VERY LOW BASE EXCHAGE CAPACITY OF AT MOST 10 MILLI-EQUIVALENTS PER 100 GRAMS.
