Influence of curing conditions on strength characteristics of cement stabilized fly ash bricks

Abstract

Fly ash is a waste produced in coal-fired thermal power stations. This calls for the development of strategies to encourage and establish technological concepts which will ensure consumption of fly ash in bulk. Fly ash has pozzolonic properties and can therefore be stabilized with either cement or lime to achieve the strength required for use as base courses in pavements. This requires carrying out unconfined compression tests on stabilized fly ash specimens prepared and cured as per standard procedures. The stabilizer content is the minimum amount of the stabilizer for which the unconfined compressive strength of the specimens complies with the specified values.
