Fly Ash of Pulverised Fuel Ash is a by-product of coal-fired power stations. It is a fine material with spherical particles. Uses include as an additive in composite cements, as a cementitious component in concrete and as a filler in certain types of asphalt.

Various test methods are specified in BS and EN Standards and include the determination of moisture content, water requirement, strength, loss-on-ignition, initial setting time, and soundness. These tests are based on those described in BS EN196. A major requirement for Fly Ash is consistency of fineness.

The activity index is the ratio (in percent) of the compressive strength of standard mortar prisms 40 x 40 x 160 mm, prepared with 75% reference cement and 25% fly ash, to standard mortar prisms prepared with reference cement alone. The equipment required comprises that used to prepare specimens and determine their compressive strength in accordance with EN196-1.
