The aim of this paper was to investigate the effect of natural carbonation on the pore structure, and elastic modulus (E-m) of alkali-activated fly ash (FA) and ground granulated blast furnace slag (GBFS) pastes after one year of exposure in the natural laboratory conditions. The chemical changes due to carbonation were examined by X-ray...

The current theory of ASR gel formation in concrete between silicic acid anions with cations and is unable to explain the differences in concentration required for gel formation between e.g. potassium and sodium or the effect of calcium on the gel formation. In this paper, a new gelation mechanism is explained by means of a condensation between...

Cement paste is the glue that holds concrete together and any improvements in material performance will come from its microstructure. For better understanding and predicting its elastic properties and fracture performance, more and more studies are carried out based on micromechanics simulations. However, the predicted results can be hardly...

Design methods for marine structures have evolved into load and resistance factor design, however existing partial safety factors related to berthing velocity and loads have not been verified and validated by measurement campaigns. In this study, field observations of modern seagoing vessels berthing in Bremerhaven, Rotterdam and Wilhelmshaven...

De Afsluitdijk is op dit moment ruim tachtig jaar oud en heeft ons al die jaren goed tegen de krachten en invloeden van het zeewater beschermd (foto 1 en 2). Rijkswaterstaat gaat de Afsluitdijk nu een grote opknapbeurt geven, zodat hij tot ten minste 2050 mee kan. De dijk wordt zodanig versterkt dat hij bestand is tegen het stijgende zeewater....

Interaction of ultrasonic waves with partially-closed surface-breaking cracks in concrete structures has been studied. Measurements have been conducted on a reinforced concrete beam containing various mechanical-load-induced cracks and compared with the baseline measurements at those locations. Influence of crack width, incident angle of waves...

Verschillende decentrale overheden in Nederland hebben in de afgelopen jaren aangegeven dat de huidige regelgeving aangaande de aan te houden verkeersbelasting voor de beoordeling van bestaande constructies leidt tot een veiligheidsniveau dat rekenkundig onvoldoende is. In opdracht van Gemeente Rotterdam is door TNO een onderzoek uitgevoerd...

In structural reliability the dependence structure between random variables is almost exclusively modeled by Gauss (normal or Gaussian) copula; however, this implicit assumption is typically not corroborated. This paper is focusing on time-variant reliability problems with continuous stochastic processes, which are collection of dependent random...

Reliability analysis is a crucial phase in assessing the safety status of new and existing structures. One of its applications is to predict the fatigue life of fatigue prone details. Two models are used to formulate the fatigue limit state: S-N curves in combination with Palmgren-Miner damage accumulation rule and linear elastic fracture...

Alkali–silica reaction (ASR) affects numerous concrete structures worldwide. However, the intervention options for ASR in existing structures are limited. Lithium is proposed to suppress expansion. In this paper, an investigation on two-chamber lithium migration as treatment against ASR is presented. First, the influence of different levels of...

Testing for the chloride threshold (also called critical chloride content) for corrosion initiation of steel in concrete has been found difficult and, at best, time consuming. Nevertheless, the chloride threshold is an important parameter in service life design of new structures and for evaluation of the remaining service life of existing...

Age and ageing can be felt as negative occurrences. For monuments, however, old age is traditionally considered to be a positive quality. Without a certain age, the designation "monument" hardly applies. Ageing can be seen as the work of time, which has always been valued: ageing was sometimes even artificially induced in the past. In this paper...

The currently available treatment techniques for concrete structures affected by alkali-silica reaction (ASR) are limited and electrochemical lithium migration has been proposed as an alternative. Lithium compounds have shown to have beneficial effects on ASR expansion when used as admixtures to fresh concrete. During the electrochemical...

Portland cement production is an energy-intensive process responsible for a significant share of the total CO2 production. Its replacement with low carbon binders from by-products of industrial processes is a sustainable alternative for innovative construction materials. In addition, the combination of low carbon binders with recycled aggregates...

Waar de rest van Nederland altijd zijn toevlucht heeft moeten nemen tot import van natuursteen om te kunnen bouwen, heeft Zuid-Limburg, net als aangrenzend België en Duitsland, altijd de beschikking gehad over lokale natuursteen, al betekent dat niet dat er geen sprake was van import van elders. Namense steen (Maaskalksteen) is prominenter...

Het innovatieprogramma Energiesprong is eind 2016 beëindigd en opgevolgd door de Stroomversnelling, een initiatief van bouwers en woningcorporaties om Nom-renovaties op gang te brengen. Met het afronden van de Energiesprong is de tijd gekomen om in de volle breedte de stand op te maken van wat we vanuit de woningmonitoring hebben geleerd van de...

The Province of Zuid-Holland encourages the development of innovations to make the provincial road network more energy efficient. This is one way the province can contribute to reducing energy consumption and CO2 emissions in accordance with the Dutch energy agreement. To this end, the Province of Zuid-Holland, Strukton Civiel and TNO have...
