Lukovic, M. (author), Schlangen, H.E.J.G. (author), Ye, G. (author), Savija, B. (author)Surface roughness of the existing concrete substrate was considered to have the greatest impact on the bond strength in repair systems. However, the influence of this parameter has been subject for debates in recent years. The effect of concrete surface roughness is not quite clear, nor there exist a clear relation between the surface roughness...conference paper 2013

Agar Ozbek, A.S. (author), Weerheijm, J. (author), Schlangen, H.E.J.G. (author), Van Breugel, K. (author)Porous concrete is used in many applications that require permeability, noise absorption or thermal insulation. However, its response under dynamic loading is generally not considered. Porous concrete has a characteristic of forming multiple cracks and subsequently fracturing into small fragments when exposed to impact loading. Therefore, with...conference paper 2013

Xuan, D. (author), Schlangen, H.E.J.G. (author), Molenaar, A.A.A. (author), Houben, L.J.M. (author)Fracture properties of cement treated demolition waste were investigated using a lattice model. In practice the investigated material is applied as a cement treated road base/subbase course. The granular aggregates used in this material were crushed recycled concrete and masonry. This results in six different types of phases in the mixture:...conference paper 2013

Qian, Z. (author), Schlangen, H.E.J.G. (author)The fracture processes in concrete can be simulated by lattice fracture model [1]. A lattice network is usually constructed on top of the material structure of concrete, and then the mechanical properties of lattice elements are assigned, corresponding with the phases they represent. The material structure of concrete can be obtained...conference paper 2013

Sangadji, S. (author), Schlangen, E. (author)Many researchers proposed self healing mechanism using hollow fibres and or microcapsule containing a modifying agent dispersed in the concrete to prolong its service life and make it more durable. A novel self healing concrete concept is proposed in this paper by using porous network concrete components. They are placed at the surface or...conference paper 2012

(author)The traffic volume and the number of heavy vehicles are growing enormously nowadays. There is a need for designing a durable asphalt pavement with innovative technologies. Pavement structures and materials with self healing and self repairing capability are believed to be very useful in such a system. This paper is aiming to understand the self...conference paper 2012

Savija, B. (author), Schlangen, H.E.J.G. (author)In this paper, a 3D lattice model is proposed as a tool to simulate chloride diffusion in (cracked) cement based materials. The procedure consists of two (computationally independent) steps: simulating fracture with the fracture lattice model, previously developed, and simulating chloride diffusion process using the newly developed transport...conference paper 2012

Qian, Z. (author), Schlangen, E. (author), Ye, G. (author), Van Breugel, K. (author)Cracking in cement-based materials is usually not easy to predict, because of the complexity of their microstructures. Concrete is a composite material of mortar and coarse aggregates, and mortar consists of cement paste and sands. The fracture processes in these materials are related, and this paper aims to reveal the relationship by developing...conference paper 2012

Qian, Z. (author), Ye, G. (author), Schlangen, E. (author), Van Breugel, K. (author)Concrete is a composite construction material, which is composed primarily of coarse aggregates, sands and cement paste. The fracture processes in concrete are complicated, because of the multiscale and multiphase nature of the material. In the past decades, comprehensive effort has been put to study the cracks evolution in concrete, both...conference paper 2012

(author)This paper outlines a project (namely PAT-ASR) which entails the development of a multi scale material performance assessment model on simulation of alkali silica reaction deployment and its effects on concrete durability. Performance models require a multi scale approach from micro (namely reaction chemistry) to macro level studies (namely...conference paper 2012
