1. Self-compacting concrete : properties of fresh and hardening concrete for civil engineering applications
Sammanfattning : 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. LÄS MER
2. Form pressure generated by self-compacting concrete : influence of thixotropy and structural behaviour at rest
Sammanfattning : 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. LÄS MER
3. Numerical Modelling of Self-Compacting Concrete Flow : Discrete and Continuous Approach
Sammanfattning : 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. LÄS MER
4. Self-compacting concrete for improved construction technology
Sammanfattning : .... LÄS MER
5. Early age properties of self-compacting concrete - Effects of fine aggregate and limestone filler
Sammanfattning : Self-compacting concrete (SCC) is a sensitive mix, strongly dependent on the composition and the characteristics of its constituents. It has to possess the incompatible properties of high flowability together with high segregation resistance, a balance made possible by the dispersing effect of water-reducing admixture combined with cohesiveness produced by a high concentration of fine particles.
