Abstract

This study investigates field application of flowing concrete in order to improve workability, duality and economic evaluation of concrete. Test results showed that slump of fresh concrete satisfied the target value before and after flowing concrete, and setting time indicated 3 hours difference depending on the mixture proportion of ready-mixed-concrete company. As for the hardened concrete, compressive strength of standard curing specimens, both control and flowing concrete, presented designed value at 28 days elapse. However, the specimens curing at atmosphere decreased the value, due to the lower curing temperature, but also performed the designed value at 91 days. For the evaluation of construction fee by value engineering(V.E) concept, a flowing method declined 4.89% of concrete construction fee, which is 4.9% reduction for materials and 25% reduction for labor expenses, compared with previous construction methods.
