Comparison of Different Types of Glass Reinforcement for HPC Facade Elements from Mechanical and Economical Aspects

摘要

Concrete as the one of the most used material in civil engineering has also a very high negative environmental impact. In recent years' environmental parameters of all building materials become the most important aspect. Especially reduction of concrete is becoming a very hot topic around the word because it can lead to the reduction of environmental impacts especially the consumption of primary energy, primary non-renewable materials and CO_2 production. Textile reinforced concrete (TRC) is one of the possibilities to reduce amount of concrete in the structures. It is possible to design very thin structures because of non-corrosive properties of textile reinforcement and thus distinctly reduce the thickness. Combination with high performance concrete (HPC) allows to creating construction with mechanical properties on a required high level. This paper presents mechanical and economical comparison of different types of AR-glass reinforcement for HPC facade elements with the same amount of concrete.
