Effect of Aggregates Kinds and Superplasticizer on Fundamental Properties of Ultra High Performance Concrete

골재 종류 및 SP제 변화가 초고성능 콘크리트 기초적 특성에 미치는 영향

In this research, the effect of types of aggregate and SP on fundamental properties of ultra-high performance concrete of 80 MPa of compressive strength was evaluated to provide solution for high cost of ultra-high performance concrete. As the results of a series of tests, the mixture using limestone and silica aggregates showed improved workability rather than the mixture using granite aggregate. For compressive strength of UHPC, the UHPC mixtures using limestone and silica aggregates showed higher compressive strength than the UHPC mixture using granite aggregate while all mixtures satisfied target compressive range.
