Glass fibre reinforced cement based composite: fatigue and fracture parameters
This paper introduces the basic fracture mechanics parameters of advanced building material - glass fibres reinforced cement based composite and its fracture and fatigue behaviour is investigated. To this aim three-point ...
Cement based composites for thin building elements: Fracture and fatigue parameters
For application in civil engineering structures and also for strengthening existing structures cement-based composites are one of the most frequently used materials. Although many studies have been conducted on the mechanical ...
Components of the Fracture Response of Alkali-Activated Slag Composites with Steel Microfibers
Knowledge of the mechanical and primarily fracture parameters of composites with a brittle matrix is essential for the quantification of their resistance to crack initiation and growth, and also for the specification of ...
Evaluation of Shrinkage, Mass Changes and Fracture Properties of Fine-aggregate Cement-based Composites during Ageing
The paper deals with the experimental determination of relative length changes development during cement based composite ageing. Special moulds with the dimensions 100 × 60 × 1000 mm were used for the measurements. These ...
Tentative Characterization of Old Structural Concrete through Mechanical Fracture Parameters
Structural concrete of the building of Vítkovice railway station from 1970s is characterized via mechanical fracture parameters. In this paper, six core-drilled cylindrical specimens with diameter of 75 mm were provided ...
Modelling of interfacial transition zone effect on resistance to crack propagation in fine-grained cement-based composites
(Italian Group of Fracture, 2017-07-03)
In this paper, the attention is paid to investigation of the importance of the interfacial transition zone (ITZ) in selected fine-grained cement-based composites for the global fracture behaviour. This is a region of cement ...
Development of shrinkage and fracture parameters in selected fine-grained cement-based composites
(EDP Sciences – Web of Conferences, 2017-05-24)
The paper summarizes results of a pilot study aimed at the evaluation of an experimental investigation focused on determination of the material characteristics development of selected fine-grained cement-based composites ...
Pilot evaluation of a fracture process zone in a modified compact tension specimen by X-ray tomography
(Italian Group of Fracture, 2017-10-03)
In the case of quasi-brittle material, there is a zone of non-linear behaving material, near the crack tip. A major part of this zone forms a so-called fracture process zone (FPZ), where mechanisms of material toughening ...
How Reliable is the Durability of RC Structures?
(Czech Technical University in Prague, 2004-12-01)
The goal of this paper is to show some trends and time profiles of the reliability index relevant to the Serviceability Limit State considering the design service life of RC structures.
Influence of freeze-thaw cycles on fracture parameters values of lightweight concrete
(Elsevier Ltd., 2010-06-06)
Freezing and thawing resistance is very important characteristic also in the case of lightweight concrete. The paper deals with the influence of periodic freeze-thaw cycles on lightweight concrete fracture parameters values. ...
