  1. 1. Numerical Modelling of Self-Compacting Concrete Flow Discrete and Continuous Approach

    University dissertation from Stockholm : US-AB

    Author : Annika Gram; KTH.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SCC; rheology; Simulation of Flow; Simulering; Flöde; Självkompakterande Betong; Reologi; TECHNOLOGY Materials science Construction materials; TEKNIKVETENSKAP Teknisk materialvetenskap Konstruktionsmaterial;

    Abstract : With the advent of Self-Compacting Concrete (SCC) that flows freely, under the soleinfluence of gravity, the wish for hassle-free and predictable castings even in complexcases, spurged the simulation of concrete flow as a means to model and predictconcrete workability. To achieve complete and reliable form filling with smoothsurfaces of the concrete, the reinforced formwork geometry must be compatible withthe rheology of the fresh SCC. READ MORE
