Dynamic computer simulation of concrete on different levels of the microstructure - part 1
Piet Stroeven, Martijn Stroeven
Izvirni znanstveni članek
Oznake:
The establishment of an experimental basis for the dependence of a mechanical property on certain structural features (and the associated micro-mechanical properties) would require extensive, cumbersome and complicated testing: mechanical testing for defining the very property, quantitative (section ...

Assessment of particle packing characteristics at interfaces by space system
Piet Stroeven, Martijn Stroeven
Izvirni znanstveni članek
Oznake:
Interest in material structure has been raised by upgrading of cementitious systems. Computer-simulation of material structure has been pursued so far by using random generators. Such systems were successfully applied for estimatingglobal properties. Realistic estimation of structure-sensitive prope ...

Stereological estimates for roughness and tortuosity in cementitious composites
Piet Stroeven
Izvirni znanstveni članek
Oznake:
Relatively weak interfaces between aggregate grains and the cementitious matrix initiate the damage evolution process leading to fracture. Coalescence between nearby interface cracks is promoted by the small nearest neighbour distances in a dense random packing of the aggregate. The fracture surface ...

Sampling concrete by too small elements; what should we do to get reliable information?
Piet Stroeven, Zhanqi Guo
Izvirni znanstveni članek
Oznake:
Macroscopically heterogeneous materials like concrete are generally sampled bytoo small, i.e., subrepresentative elements that can be either of 2D (section images) or of 3D nature (specimens). Based on scientific notions, like stochastic heterogeneity and structure-sensitivity, which are at the very ...

Shape characterization of concrete aggregate
Jing Hu, Piet Stroeven
Izvirni znanstveni članek
Oznake:
As a composite material, the performance of concrete materials, can be expected to depend on the properties of the interfaces between its two major components, aggregate and cement paste. The microstructure at the interfacial transition zone (ITZ) is assumed to be different from the bulk material. I ...

Application of image analysis to assessing critical pore size for permeability prediction of cement paste
Jing Hu, Piet Stroeven
Izvirni znanstveni članek
Oznake:
This paper explores image analysis techniques that provide insight into the nature of pore structure as observed in backscattered electron images of polished sections. On the basis of mathematical morphology, the pore size distribution is characterised and the critical pore size is determined for ce ...

Self-healing capacity of concrete - computer simulation study of unhydrated cement structure
Huan He, Zhanqi Guo, Piet Stroeven, Martijn Stroeven, Lambertus Johannes Sluys
Izvirni znanstveni članek
Oznake:
Aggregate occupies at least three-quarters of the volume of concrete, so its impact on concretećs properties is large. The aggregatećs influence on the non-hydrated part of the matured paste is assessed by concurrent algorithm-based computer simulation system SPACE in this paper. A distinction is ma ...

Deciphering the finest imprint of glacial erosion: objective analysis of striae patterns on bedrock
Piet Stroeven, Arjen Peter Stroeven, Jing Hu, Jean-Louis Chermant, Michel Coster
Izvirni znanstveni članek
Oznake:
The aim of this study is to compare the efficiency of different mathematical and statistical geometrical methods applied to characterise the orientation distribution of striae on bedrock for deciphering the finest imprint of glacial erosion. The involved methods include automatic image analysis tech ...
