Cements

“…At the present time various types of resin cements are being tested and indications are that certain types of furan resin cements may prove superior to materials used in the past. The use of acidproof cements and brick linings in chemical plants and, steel mills has been discussed (IS, 27,42,48,57,74,87). Ceramics based on lithium aluminosilicate have high thermal shock resistance and good chemical resistance at high temperatures (82).…”
