TL;DR: In this paper, the effects of FA addition on the compressive strength f cm and fracture toughness of plain concrete are presented, and the results of the K Ic S and the f cm are convergent qualitatively.

TL;DR: It can be concluded that composites with 20% addition of FA are characterized by low permeability and therefore high durability, in matured concretes the smallest cracks occur in composite with the 20% FA additive.

TL;DR: In this paper, the fracture toughness during Mode I loading of concretes containing the 0, 20% and 30% addition of class F fly ash (FA), was investigated. And the results of the research show the usefulness of the Digital Image Correlation (DIC) method in experiments of that type.

TL;DR: In this paper, the authors presented the results of compressive strength and fracture toughness tests of concrete composite modified with the addition of siliceous fly ash (FA) using the Digital Image Correlation (DIC) system.

TL;DR: In this article, the optical and contactless DIC technique was used for the examination of fracture processes in concrete with fly ash under shear loading, and the results showed that unmodified concrete are characterised by greater brittleness, whereas composites made on the basis of the binary binder behave as quasi-plastic materials in the fracture process.
