Fly Ash Detection

Fly ash is tiny ash particles emitted during the combustion of fuel (mainly coal), also known as soot. As an important mineral admixture for concrete, it is widely used in the production of commercial concrete. The activity index of fly ash is an important parameter and indicator. The main function of fly ash is to improve the workability and durability of concrete. It is widely used in preparing large-volume concrete and pumping concrete. If the activity of fly ash does not meet certain standards, it will directly affect the strength and quality of concrete.

STEMart provides comprehensive fly ash detection services to ensure that their fly ash meets the required standards and that it is safe and effective for use in concrete. Fly ash testing helps improve quality, improve safety and reduce costs.

Test Samples

• Class C fly ash (high calcium ash): obtained by burning lignite or sub-bituminous coal, with pozzolanic properties and gelling properties
• Class F fly ash (low calcium ash): obtained by burning anthracite or bituminous coal, with pozzolanic properties
• Composite ash

Standard Tests

• Fineness
• Loss on ignition
• Water demand ratio
• Moisture content
• Sulfur trioxide content
• Free calcium oxide content
• Stability
• Activity index
