Abstract
Research of crack healing in concrete by autogenous healing, secondary crystallization admixtures or by microorganisms often uses large test samples. In order to develop and identify the most suitable method of crack healing, it is necessary to create many samples and examine them with different boundary conditions. This paper presents a newly designed small textile reinforced concrete test sample, and its production technology, which contains a large amount of various cracks. The small size allows for simultaneous testing of large numbers of test samples under identical conditions which helps to evaluate objectively the efficiency of various additives supporting the autogenous healing of concrete.Keywords
