Effect of aggregate type and fly ash content on properties of self-compacting concrete
Abstract
The paper presents the results of experimental study of Self-Compacting Concrete in fresh and hardened state. Five mixtures were made, in which the content of the following components was varied: aggregates, fly ash in as-delivered state and the total amount of the paste (a mixture of water, mineral additive and a binder). Fresh concrete tests included determining the following properties: bulk density, slump-flow, V-funnel time, height ratio of the L-box, as well as ambient temperature measurement. In the hardened state the tested properties included: hardened concrete density, compressive strength, flexural strength, ultrasonic pulse velocity and water penetration depth. Tests have shown that the increase in the content of the paste can improve the workability, as well as reduce the negative effect of the larger fly ash particles presence on the properties of the fresh concrete.
