Design considerations and sustainability of self-compacting concrete

abstract
Self-compacting concrete (SCC) differs from conventional vibrated concrete (CVC) in the rheological behaviour, which is achieved by adequate mix design. The application and production requirements also pose demands on the mix design and workability. Effective production requires adequate strength control. The use of Portland Cement promotes a rapid early age strength development, but it comes with a relative high impact on the environment since decarbonation and a high energy demand accompany cement production. Supplementary cementitious materials have been widely applied to improve the sustainability of concrete but the rate of early age strength development often is compromised. This paper discusses the application of SCC for concrete structures with regard to mix design and its environmental impact. 24 CVCs and SCCs with a variety of mix designs and rheological characteristics were selected from literature. The two objectives of this study were: 1) to determine the environmental impact with regard to the global warming potential and MKIcosts (calculated with the Dutch CUR-tool ‘Green Concrete 3.2’) and 2) to relate the environmental impact with the compressive strength at 24h and 28d. Quantifying the trade-off between the use of Portland Cement and other mixture components is important information to balance production requirements and to determine the environmental impact of concrete structures produced with SCC.
