Abstract
In this paper the basic procedure for the development of self-compacting lightweight concrete (SCLC) is presented. By using a rheological optimization approach SCLC with different unit weights could be developed. Further, the experiments carried out on hardened SCLC showed that its mechanical and fracture mechanical properties are comparable to those of LWAC with equal compressive strength. With regard to the brittle failure of LWAC and SCLC the effect of the addition of different amounts of steel, polypropylene and glass fibres on the rheological properties of fresh SCLC as well as on the properties of hardened concrete was investigated. Furthermore, a series of deformation controlled direct tension tests on notched prisms was performed in order to investigate the fracture mechanical behaviour of the developed concretes with and without fibre reinforcement.
