Reasons to the low use of self-consolidating concrete in Norway

Abstract

According to several research papers, self-consolidating concrete (SCC) should be able to offer advantages over conventional vibrated concrete (CVC) [1 - 3 ] . Nevertheless, in Norway SCC has a relatively low market share, and the use is mainly concentrated to the capitol and nearby districts. In this paper, through interviews with professionals in the construction industry, possible causes of the low use of SCC in Norway have been investigated. Lab tests have also been conducted to study effects of variations in the concrete composition, as well as the effects of poor execution that can occur due to inadequate competence of construction workers. According to the paper ́s results, perceived advantages of the SCC are not nearly as many as those mentioned in various research papers [2 - 4 ] .
