The American Society for Testing and Materials (A.S.T.M.) is presently considering revisions to A.S.T.M. specifications for brick which will permit the use of coring up to 40 percent of the brick cross-sectional area in any plane parallel to the bearing surface. In flyash brick the reduced solid volume and thinner cross-sectional area will result in a lighter unit weight and should also result in improved thermal insulating properties which are a vital consideration in view of the current energy shortage. The reduced solid volume and thinner cross-sectional area also affects the sodium silicate requirements and other variables in the batch composition. This report discusses the results obtained by varying the sodium silicate content and other variables in tests at a pilot plant operated by the Coal Research Bureau, West Virginia University, under a contract to Energy Research and Development Administration--Fossil Energy. Each of the three flyashes tested: a lignite, one from northern West Virginia, and one from western Kentucky will be discussed individually.
