This paper presents the results of Mode I fracture toughness tests of concrete with fly ash (FA) loaded in Mode I. Concrete composites with the addition of 0%, 20% and 30% siliceous FA were analysed. Fracture toughness tests were performed on a MTS 810 testing machine. The studies examined the effect of FA additive on the quasi-static fracture toughness KIcS. The analysis of the results revealed that a 20% FA additive causes an increase of KIcS value, while a 30% FA additive causes a decrease on fracture toughness. Additionally, the results demonstrate the possibilities of practical application of ARAMIS system for analysing the development of defects in the micro-structure of concretes containing FA additives. This system can be useful for macroscopic estimation of crack propagation. |
