  2. 1. Self-compacting concrete : properties of fresh and hardening concrete for civil engineering applications

    Author : Sofia Utsi; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : This licentiate thesis consists of three papers, A-C. In Paper A the consequence of using self-compacting concrete for civil engineering applications regarding the fresh and young stage and possible consequences on production techniques are studied. READ MORE

  4. 2. Form pressure generated by self-compacting concrete : influence of thixotropy and structural behaviour at rest

    Author : Peter Billberg; Johan Silfwerbrand; Kamal Khayat; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; self-compacting concrete; thixotropy; structural build-up; form pressure; rheometer; viscometer; instrumented pressure tube; Building engineering; Byggnadsteknik;

    Abstract : Self-compacting concrete (SCC) offers rational and fast casting process since it merely has to be poured, or pumped, into the formwork without any compaction work needed. But this can be at the cost of high form pressure. However, reported results show that SCC can act thixotropically, i.e. READ MORE

  6. 4. Numerical Modelling of Self-Compacting Concrete Flow : Discrete and Continuous Approach

    Author : Annika Gram; Johan Silfwerbrand; Ali Farhang; Mette R. Geiker; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SCC; rheology; Simulation of Flow; Simulering; Flöde; Självkompakterande Betong; Reologi; Construction materials; 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
