Sulphate resistance of mortar, containing ground brick clay calcined at different temperatures
The sulphate resistance of mortar containing GCBC (ground calcined brick clay) calcined at different tempertaures (600 deg C to 1100 deg C) and GS (ground sand) as cement replacement materials is investigated. Also the porosity, pore size distribution and strength of a selection of these mortars are determined. Mortars containing GCBC calcined at a temperature higher than 900 deg C show superior sulphate resistance to those containing GCBC calcined at temperatures below 900 deg C. Although the intruded pore volume is higher at early ages of curing, the inclusion of GCBC in the mortars leads to refinement of pore structure and its contribution to strength is significant after a curing period of 90 days. The influence of the incorporation of GCBC (calcined at different temperatures) on the sulphate resistance of mortar, is discussed in terms of fundamental mechanisms.
