Autoclaved lime-quartz materials I. Some factors influencing strength
AbstractAutoclaved materials were made with varying bulk C/S ratios and quartz particle sizes, with and without added kaolinite, and their strengths, densities, phase and C-S-H compositions and porosities determined. If much unreacted quartz remains, strength is controlled by its particle-size distribution and the porosity, but if the material is largely C-S-H, the distribution of particle types within the C-S-H has a major effect. Increase in C-S-H crystallinity can either raise or lower strength depending on the amount of unreacted quartz. Addition of kaolinite raises the crystallinity of the C-S-H and may also accelerate its formation.
