ABSTRACT:
A refractory composition, suitable for ramming, casting, or gunning, which can be heated rapidly without exploding is made from sized refractory aggregate bonded with from 0.1% to 3% MgSO.sub.4, from 0.1% to 2% sodium gluconate, and from 0.1 to 2% B.sub.2 O.sub.3 in the form of a soluble boron compound, boric acid being a preferred form. To inhibit explosion of the composition upon rapid heating, the sum of the per cent sodium gluconate and boric acid should be over 0.8, preferably over 0.9.
