- Abstract
Combustion temperature of oil shale in pulverized fuel boilers and in fluidized bed combustion equipment is different. High temperature burnt oil shale from pulverized combustion boilers and low temperature burnt oil shale from a CFB (Circulating Fluidized Bed) boiler differ in their mineral composition and surface properties of ash particles. Variations in the properties of ashes affect hydraulic properties of burnt oil shale as a binder or as the main constituent of Portland cement. Differences in the frost resistance of concretes made with various second main constituents show how significant is the type of hydration of the second main constituent in terms of the durability. Alternate immersiondrying tests were carried out to analyze the frost resistance of concretes compared to the other main constituents. The oblective of this work was to investigate the influence of various burnt oil shales as the main constituent of Portland cement on the durability of concrete compared to the main constituent such as pulverized limestone.
