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.
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 ...
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 ...
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 ...
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 ...
Fracture properties of concrete specimens made from alkali activated binders.
(IOP Publishing, 2017-09-15)
The aim of this paper is to quantify crack initiation and other fracture properties – effective fracture toughness and specific fracture energy – of two types of concrete with an alkali activated binder. The beam specimens ...
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 ...
Shrinkage, weight loss and fracture parameters of selected polymer-modified cement mortars during ageing
(VŠB – Technical University of Ostrava, 2017-06-01)
Results of pilot experiments focused on monitoring of shrinkage, weight loss and mechanical fracture properties of two selected polymer-modified cement mortars (PCM) during their aging are presented in the paper. Comparison ...
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 ...
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 ...
