| Summary: | This study discusses the influence of partial replacement of sand with quarry dust on
the properties of fresh high performance concrete. Considering the decrease in the
sources of natural sand, it is necessary to identify alternative source, such as quarry
dust to reduce the utilisation of sand in the industries requiring it. In this study,
replacement proportion of sand with quarry dust used was 20% in all the high
performance concrete mixes except in the normal Portland cement control high
performance concrete mix. The properties of fresh high performance concrete were
determined in the aspects of slump, slump flow, V-Funnel flow, air content, density
and temperature. Results obtained showed that partial replacement of sand with quarry
dust were able to increase the workability and flowability, as well as the air content of
fresh high performance concrete. Besides that, it was observed that V-Funnel flow
was more suitable to determine the flowability of fresh high performance concrete
compared to the conventional slump flow |
