(author)Land use regression (LUR) models have been used to model concentrations of mainly traffic-related air pollutants (nitrogen oxides (NOx), particulate matter (PM) mass or absorbance). Few LUR models are published of PM composition, whereas the interest in health effects related to particle composition is increasing. The aim of our study was to...article 2014

(author)Voor de conservering van aangetaste (natuur)steen in monumentale gebouwen, en dan vooral voor schadetypen die kunnen worden omschreven als afzanden, poederen of verkruïmelen, zijn door de industrie zogenaamde steenverstevigers ontwikkeld. Ethylsilicaten (kiezelzure esters) worden al langere tijd gebruikt. Dit type steenversteviger is...bookPart 2014

Polder, R.B. (author), Peelen, W.H.A. (author)This paper reviews 25 years of experience with cathodic protection of steel in concrete in The Netherlands. Three phases have passed from the late 1980s until present: pioneering, development and maturity. In the first period CP was mainly applied to precast elements corroding due to mixed in chlorides. The parties involved worked together to...bookPart 2014

Kruithof, J.J. (author)Throughout Europe, structures such as bridges and viaducts are approaching the end of their service life. Material degradation is a direct consequence of ageing and leads to reduced resistance to environmental impacts. In the meantime, some of these environmental impacts, or loads for short, have increased. Traffic loads and extreme weather...report 2014

Een stad biedt werk, vertier, recreatie en sociale cohesie. Woonruimte en leefruimte dus. Dat is al eeuwen zo. In de toekomst zal een vitale stad nog meer een stad van verbindingen zijn. Met als resultaat: veilig verkeer zonder congestie, ongeevenaarde luchtkwaliteit en een circulaire economie....article 2014

Lubelli, B.A. (author), van Hees, R.P.J. (author)Zoutkristallisatie is één van de meest voorkomende oorzaken van schade aan poreuze bouwmaterialen; het komt voor in verschillende klimaten. Vooral historische gebouwen vertonen vaak ernstige aantastingsverschijnselen veroorzaakt door zouten. Zouten in poreuze materialen kunnen leiden tot schade door hun interactie met vocht.

Maljaars, J. (author)Some existing steel bridges have been constructed from steels with a toughness that does not fulfil the requirements in modern standards. In such a case, standards for bridges do not provide an alternative assessment route. Yet such bridges may still be fit for purpose. This paper presents an assessment method for structural safety and for the...conference paper 2014

Salomons, E.M. (author), Zhou, H. (author), Lohman, W.J.A. (author)Traffic noise mapping of cities requires large computer calculation times. This originates from the large number of point-to-point sound propagation calculations that must be performed. In this article it is demonstrated that noise mapping calculation times can be reduced considerably by the use of parallel computation on the Graphics Processing...conference paper 2014

Pacheco, J. (author), Savija, B. (author), Schlangen, E. (author), Polder, R.B. (author)The influence of concrete cracking upon reinforcement corrosion is complex. Cracks allow fast penetration of chlorides, potentially leading to a shorter initiation period of reinforcement corrosion. Structural regulations control acceptable crack width values based on the exposure class of the structure. These regulations are limited to crack...bookPart 2014
