Ye, S.Q. (author), Verhagen, H.J. (author)In order to develop a new philosophy of flood safety in terms of probability of a certain level, two mathematical models of breach growth in sandy dikes have become available to determine the flood discharge in case of dike failure. BREACHES 1.0, developed at Alkyon/Delft Hydraulics (Steetzel) and BRES 1.0 at Delft University of Technology ...conference paper 1999

Ye, G. (author), Van Breugel, K. (author)This paper describes a computer-based numerical model for the simulation of the development of microstructure during cement hydration. Special emphasis is on the algorithm for characterizing the pores. This includes the porosity and the pore size distribution and the topological properties of the porous network. In order to do so, a serial...journal article 2003

Koleva, D.A. (author), De Wit, J.H.W. (author), Van Breugel, K. (author), Lodhi, Z.F. (author), Ye, G. (author)The present study explores the formation of corrosion products on the steel surface (using as-received low carbon construction steel) in reinforced concrete in conditions of corrosion and subsequent transformation of these layers in conditions of cathodic protection (CP).journal article 2007

Ye, G. (author), Van Breugel, K. (author)In recent years, the durability of reinforced or prestressed concrete structures has become a main concern. A key parameter in durability predictions is the microstructure of the surface zone of concrete structures, i.e. the “covercrete”, more in particular the connectivity of the pores in the cement paste matrix. In this paper, the connectivity...journal article 2009

Zhou, J. (author), Qian, S. (author), Sierra Beltran, M.G. (author), Ye, G. (author), Van Breugel, K. (author), Li, V.C. (author)Nowadays limestone powder and blast furnace slag (BFS) are widely used in concrete as blended materials in cement. The replacement of Portland cement by limestone powder and BFS can lower the cost and enhance the greenness of concrete, since the production of these two materials needs less energy and causes less CO2 emission than Portland cement...journal article 2009

Qian, Z. (author), Ye, G. (author), Schlangen, H.E.J.G. (author), Van Breugel, K. (author)Numerical modeling of fracture processes of brittle materials, such as cement paste, mortar, concrete and rocks, started in the late 1960s when the discrete and smeared cracking models were introduced. In the 1990s, Schlangen and van Mier proposed another numerical model to compensate the drawbacks of the discrete and smeared cracking models,...conference paper 2010

(author)Salt marshes are distributed along more than 400 km of the Jiangsu coast in Eastern China, which are regarded as important habitats and serve as coastal protection as well. Previous research has proven that salt-marsh vegetation can reduce current velocity and dampen waves by its stems and leaves. Reversely, hydrodynamic forces also have a...conference paper 2011

Zhang, Q. (author), Ye, G. (author)When a concrete structure is exposed to high temperature, the mechanical damage and chemical transformation take place simultaneously, which will change the microstructure of material. On the other hand, the mechanical properties and transport properties depend on the development of microstructure of cement paste. In order to study the...journal article 2011

Ma, Y. (author), Hu, J. (author), Ye, G. (author)Alkali-activated fly ash (AAF) is a promising material that exhibits comparable material properties as cement-based materials but with much less CO2 emission. In the present work, the effect of activating solution (SiO2 and Na2O content) on the performance of AAF was studied by means of isothermal calorimetry and X-ray diffraction analysis....journal article 2012

Ye, Q. (author)This thesis presents the development a generic morphological model for both structured and unstructured grid and the extension to a biogeomorphological model. For the morphological model, numerical algorithms are adjusted to adapt unstructured grid and are validated against analytical solutions and flume experiments. For the bio-geomorphological...doctoral thesis 2012

Lukovic, M. (author), Ye, G. (author), Van Breugel, K. (author)This paper highlights the importance of achieving durable and long-term predictable repair of reinforced concrete structures. The performance of concrete repair in past and current engineering practice, including all types of repair and application of different materials, is often unsatisfactory. One of the reasons for this lays in the fact that...conference paper 2012

Zhang, Q. (author), Ye, G. (author)Portland cement paste is a multiphase compound mainly consisting of calcium-silicate-hydrate (CSH) gel, calcium hydroxide (CH) crystal, and unhydrated cement core. When cement paste is exposed to high temperature, the dehydration of cement paste leads to not only the decline in strength, but also the increased pore pressure in the paste. In this...journal article 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
