Mechanical tests on samples of textile glass reinforcement were performed in the Klokner Institute. These tests will be used for the determination of elasticity modulus of textile glass reinforcement and the assessment of maximal stress at samples. Both mentioned quantities are necessary for the further modeling of structures and for the design of elements made from TRC (textile reinforced concrete). In total 10 samples made from one piece of 2D net (product of V. FRAAS, GmbH, Germany) were tested. The textile glass AR-glass reinforcement (alkali - resistant glass) with fineness 2400 TEX [g/km] that is commonly supplied in size of 1 x 2 m was tested. First 5 samples were prepared in direction of warp (direction of the load-bearing reinforcement) and then remaining 5 samples were made from the transverse direction (weft direction). These samples were loaded by s constant force increasing up to the collapse. Then the modulus of elasticity of textile glass reinforcement and stress at strength limit were determined from the monitored data.
