Textile-reinforced lightweight wood-concrete components
Overhead presentation: Today's environmental awareness requires developing economically defendable products on the market. Therefore, energy-extensive products have to be replaced by more ecological ones. As a sort of regenerative material wood chips and wood flavour arise in the woodworking industry. These materials can be used as aggregate in the production of lightweight concrete. Timber's positive physical properties are applied to this lightweight wood concrete (LWC). The ability of sawing, drilling, nailing and screwing has positive effects in processing LWC. Budgeted costs are on the same level like conventionally used concretes without wood. Negative influences on the hardening of concrete caused by several components of timber can be eliminated by help of suitable pre-treatment and added substances. Hence LWC can fulfil a great number of statically tasks. Due to the lower weight of LWC, smaller cross-sections are possible. The concrete cover can be reduced significantly with the additional use of textile fibres as reinforcement. The aim of the research was to describe the alliance between cement and fibres, to evaluate important parameters for the development of a dimensioning aid for constructions reinforced by textile fibres. The bearing capacity, bond and material constants have been pointed out with help of known analysis theories which have been extended by new aspects. Both the measurements as a result of a series of experiment and the modelling analysis show nearly the same bearing behaviour, either in the elastic branch or in the branch after cracking.
