Abstract
Flexural and bond behaviour of chemically prestressed concrete elements with textile reinforcement. Chemical prestressing is a method of introducing stresses into concrete with the use of expansive admixtures instead of mechanical devices. The paper presents an approach to chemical prestressing of thin textile reinforced concrete elements. Measurements of free and restraint expansion are described, as well as experimental investigations regarding flexural and bond behaviour of thin specimens with carbon textile grids. Results of four-point bending tests on slab members and of bond tests are presented. It was confirmed that the use of expansive concrete influences the behaviour of textile reinforced concrete specimens. The cracking load can be increased with increasing amount of expansive admixture, as well as the deflection at first cracking. Similarly, higher maximal bond stresses are achieved for specimens made of expansive concrete that of control mixture. The results are evaluated and an overview is provided.
