Abstract
The effect of firing temperature in the range 800 – 1600°C and heat treatment duration (60 h at 1350 – 1400°C) on shrinkage and growth indices, porosity, and strength for specimens based on HCBS of composite composition (bauxite and VFQG), and also with added clay, is studied. Depending on specimen composition there is low shrinkage within the limits of 0.4 – 1.15% in the range 1100 – 1200°C and significant growth (2.0-.27%) as a result of secondary mullite formation occurring at 1300 – 1500°C.
