Koleva, D.A. (author), Jonkers, H.M. (author), van Breugel, K. (author)The improvement of material properties of cement-based materials e.g. reduced permeability, porosity, uniform distribution of hydration products, etc. is of a significant importance and related to durability and sustainability of concrete and reinforced concrete structures. With this respect, a recent and novel approach is to "create" self...journal article 2013

Toledo Filho, R.D. (author), Koenders, E.A.B. (author), Pepe, M. (author), Cordeiro, G.C. (author), Fairbairn, E. (author), Martinelli, E. (author)The Brazilian construction industry is committed to delivering the venues and infrastructure of the Rio 2016 Olympic and Paralympic Games with zero increase in carbon dioxide emissions, reduced consumption of raw materials, increased use of renewable materials and 100% local recycling of construction waste. This in turn has led to significant...journal article 2013

Vervuurt, A.H.J.M. (author), Braam, C.R. (author), Schols, I. (author)Het rijkswegennet in Nederland telt 57 tunnels, belangrijke en veelal onmisbare schakels. Deze kostbare objecten vragen in beheer en exploitatie de nodige aandacht met name als ze de ontwerplevensduur naderen. Circa een derde, voornamelijk afgezonken tunnels, is halverwege deze levensduurjournal article 2013

Sandhaas, C. (author), Van de Kuilen, J.W.G. (author)Wood is highly anisotropic and shows ductile behaviour in compression and brittle behaviour in tension and shear where both failure modes can occur simultaneously. A 3D material model for wood based on the concepts of continuum damage mechanics was developed. A material subroutine containing the developed model was implemented into a standard FE...journal article 2013

Ahmed, A. (author), Sluys, L.J. (author)Experimental testing and numerical analysis often travel in tandem in a design process. Recent advances in novel numerical techniques to simulate mesh objective crack propagation offer a great potential for accurate and efficient damage analysis of composite laminates. This paper presents a numerical study on computational modeling of mesh...journal article 2013

Nahar, S.N. (author), Mohajeri, M. (author), Schmets, A.J.M. (author), Scarpas, T. (author), Van de Ven, M.F.C. (author), Schitter, G. (author)One of the challenges in designing recycled asphalt mixtures with a high amount of RAP is to estimate the blending degree between RAP binder and the added virgin bitumen. The extent of blending is crucial in this case as asphalt concrete response is influenced by the final binder properties. This paper focuses on the evaluation of interaction...journal article 2013

Van Dalen, K.N. (author), Wapenaar, C.P.A. (author), Halliday, D.F. (author)Virtual-source surface wave responses can be retrieved using the crosscorrelation (CC) of wavefields observed at two receivers. Higher mode surface waves cannot be properly retrieved when there is a lack of subsurface sources that excite these wavefields, as is often the case. In this paper, we present a multidimensional-deconvolution (MDD)...journal article 2013

Schipper, H.R. (author), Grünewald, S. (author), Kok, M.A.D. (author), Nijsse, R. (author), Raghunath, P. (author)In an earlier article (CPI issue of August 2011 [1]) a method was presented for producing precast curved panels with a thickness of a few centimeters using the 'flexible mould method'. This method is the central theme in the PhD study of the first author on the realization of freeform architecture in concrete. The concrete panels manufactured...journal article 2013

Wang, X. (author), Xing, F. (author), Zhang, M. (author), Han, N. (author), Qian, Z. (author)The recovery behavior for strength and impermeability of cementitious composites embedded with organic microcapsules was investigated in this study. Mortar specimens were formed by mixing the organic microcapsules and a catalyst with cement and sand. The mechanical behaviors of flexural and compression strength were tested. The results showed...journal article 2013

Wiktor, V. (author), Jonkers, H.M. (author)The goal of this study is to develop a repair system for cementitious materials which features improved properties compared current available systems in terms of long term efficiency and environment friendliness. Thus, a bacteria-based repair system has been developed. The mineral formation mediated by bacterial activity results in the crack...journal article 2013

Van der Put, T.A.C.M. (author)A derivation is given of simplified, exact stability design rules according to limit analysis, applied to timber beam-columns. These rules are lacking but are necessary to be able to provide real and calculable reliability as is required according to European pacts and laws. Necessary therefore are the obtained exact combined bi-axial bending,...journal article 2013

(author)This paper investigates changes in tire/pavement noise caused by variations in the road surface characteristics. This research is based on the analysis of noise and surface characteristics collected from sections with 25 mm thickness thin layer surfacings in the Netherlands. Investigations are first performed on the measured noise levels in 1...journal article 2013

Sangadji, S. (author), Schlangen, H.E.J.G. (author)To repair concrete cracks in difficult or dangerous conditions such as underground structures or hazardous liquid containers, self healing mechanism is a promising alternative method. This research aims to imitate the bone self healing process by putting porous concrete internally in the concrete structure to create a porous network similar to ...journal article 2013

Lantsoght, E.O.L. (author), Van der Veen, C. (author), Walraven, J.C. (author), De Boer, A. (author)Upon assessment of existing reinforced concrete short-span solid slab bridges according to the recently implemented Eurocodes that include more conservative shear capacity provisions and heavier axle loads, a number of these structures were found to be shear-critical. The results from recent experimental research on the shear capacity of slabs...journal article 2013

Jönsthövel, T.B. (author), Van Gijzen, M.B. (author), Vuik, C. (author), Scarpas, A. (author)Large discontinuities in material properties, such as those encountered in composite materials, lead to ill-conditioned systems of linear equations. These discontinuities give rise to small eigenvalues that may negatively affect the convergence of iterative solution methods such as the preconditioned conjugate gradient method. This paper...journal article 2013

Van Hemert, P.H.A. (author), Rudolph, E.S.J. (author), Zitha, P.L.J. (author)Storage of CO2 in depleted gas reservoirs and saline aquifers is being considered to prevent its emission to the atmosphere and thus the subsequent climate changing effects. The injection of large amounts of anhydrous carbon dioxide in the under- ground will lead to salt precipitation as connate water evaporates in the CO2 flux. This...journal article 2013

Molenaar, A.A.A. (author)This paper discusses the possibilities to build durable and sustainable pavement structures in developing countries. Attention will be paid to geometric design aspects which have a significant effect on pavement life. Following this attention will be paid to the importance of controlling wheel loads rather than axle loads. Also the importance of...journal article 2013
