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

    University dissertation from Stockholm : US-AB

    Author : Annika Gram; Johan Silfwerbrand; Ali Farhang; Mette R. Geiker; [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

    Abstract : In Sweden, buildings are responsible for about 40 % of total energy use and about 10 % of total CO2 emissions Today more than 60 % of existing Swedish residential buildings are over 40 years old and are in need of major renovation. In addition, 15 % of all multi-family buildings and 27 % of all single-family houses were built before 1945. READ MORE
