A study on the properties of freshly mixed high performance concrete

The physical properties of freshly mixed high performance concrete were inv estigated. Physical state and quality of fresh concrete were monitored batc h by batch. The properties of fresh high performance concrete were determin ed in respect of slump, slump flow. V-funnel flow, ail content, temperature , and unit weight. It was observed that the properties are interrelated, pa rticularly the flow and the air content. The indication of flowability was more pronounced in terms of V-funnel flow than slump Row. This result sugge sts that the traditional slump test is not efficient to evaluate the workab ility and flowability of high performance concrete. (C) 1999 Elsevier Scien ce Ltd. All rights reserved.
