Abstract

Textile reinforced concrete (TRC) found its application in real practice and several producers and companies included TRC ́s elements into their production program. The most popular and widespread are slim façade panels with high aesthetic quality and excellent durability. Curing conditions influence the final properties, which is important especially in precast production where special devices can be used. This paper deals with experimental investigation of bond characteristics of slabs made from TRC hydrothermally cured in autoclave device and reference slabs cured in laboratory conditions for 28 days. Dimension of TRC slabs was 230 x 100 x 20 mm. Compressive strength 100 MPa characterizes used cement matrix (laboratory cured after 28 days). Basalt and AR-glass fabrics with different properties were used as reinforcement. Three-points bending test with clear span of supports 200 mm evaluated maximum bond capacity and load-deflection diagrams described character of failure and ductility.
