Abstract
A binder solution of a phenolic novolak resin in solvent, preferably furfuryl alcohol containing at least one chemical agent such as amines containing one to five, preferably two to four, nitrogen atoms, glycerine or mixtures thereof. Preferably, the binder solution contains about 0.2 to about 1.5 weight percent water. The binder solution is for binding refractory objects, preferably those containing doloma (calcined dolomite) aggregate. Methods of mixing these ingredients and using the mixture are also disclosed. Bricks made from the doloma aggregate mixed with the binder solution show good ambient temperature green strength and enhanced modulus of rupture after curing and coking.
