Abstract
A composition of a ramming silica mixture based on quartzite filler and HCBS of quartz sand plasticized by an additive of refractory clay and having a total clay content of at most 2% is presented. Three methods of molding (compaction) are considered, namely, pneumo(vibro)ramming, vibropressing, and static pressing. The first is shown to give maximum compaction. The effects of some process factors on the properties of the new refractory material are described. The suggested mixture promises to serve well in rammed monolithic linings of heating units
