SELF-COMPACTING CONCRETE FOR TEXTILE REINFORCED ELEMENTS
The textiles with rovings made of fiber-threads through basketry which are oriented parallel with the occurring stresses instead of randomly-dispersed short fibers in concrete can increase obviously the efficiency of fiber-reinforcing.Moreover,textiles have no risk of corrosion due to the ingress of chlorides and carbonation of concrete and are lightweight,flexible,high-strength as well as non-magnetic.Therefore,textile reinforced concrete structures are expected to have wide application foregrounds.In order to ensure that the bond between fiber and matrix and avoid pores,both of which influence the strength of the structure,the biggest grain size of matrix must be enough small and matrix must have a very nice workability and consistency so that they fiilly penetrate the textile.As prestressed textile reinforced concrete is concerned,the self-compacting capability of matrix is indispensable because vibration can influence the application of prestress.Therefore a new kind of self-compacting concrete(SCC)named as fine concrete is developed.The central task of this paper is development and optimization of the matrix in term of its chemical compatibility with the materials(alkali-resistant glass fibres)as well as a suitable consistency and workability based on test methods used for self-compacting concrete,rapid hardening,and high early strengths,for planned production processes.
