CONCRETE Optimizing the Use of Fly Ash in Concrete

In the production of fly ash, coal is first pulverized in grinding mills before being blown with air into the burning zone of the boiler. In this zone the coal combusts producing heat with tempertures reaching approximately 1500°C (2700°F). At this temperature the non-combustible inorganic minerals (such as quartz, calcite, gypsum, pyrite, feldspar and clay minerals) melt in the furnace and

FLY ASH CONCRETE WHAT ARE THE REASONS FOR

Increased durability, dense fly ash concrete helps keep aggressive compounds on the surface. Reduced shrinkage, the lubricating action of flyash concrete reduces water content and drying shrinkage. Reduced heat of hydration, the pozzolanic reaction between fly ash and lime generates less heat, resulting in less thermal cracking when fly ash is used to replace portland cement. Reduced alkali
