Abstract

The relationship between microstructure and properties of high-strength mortar cured at various conditions were investigated using normal portland cement and silica fume cement containing 10% of silica fume. By the steam curing, the strength of was remarkably increased through the acceleration of cement hydration and pozzolanic reaction. The strength of mortar after steam-curing was ,however, hardly ti1ough it was additionally autoclave-cured and oven-cured. The of stress-strain curve of mortar under the loading of compressive strength V:ls improved by temperature-increasing curing. modulus elasticity of the SFC mortar was than of NPC mortar especially temperature-increasing curing. reason for these phenomena were discussed in relation to the microstructure-related characters including porosity, pore size distribution, of mortar, and kind, crystallinity, quantity and rearrangement of produced hydrates.
