Borax has been identified as a possible crystallization modifier for sodium sulfate. Understanding the effect of borax on factors influencing transport and crystallization kinetics of sodium sulfate helps to clarify how this modifier might limit crystallization damage. It has been observed that the addition of borax to sodium sulfate solutions...

De Noordersluis bij IJmuiden is één van de grote infrastructurele werken in vooroorlogs Nederland, uitgevoerd in beton (Fig. 1). De bouw van de nieuwe sluis was onderdeel van een reeks verbeteringen aan het Noordzeekanaal: In 1909 was een staatscommissie ingesteld '(om)dat opnieuw de vraag rees of de belangen van Nederland in het algemeen en van...

This paper considers local buckling of perforated square aluminium plates. Plates of various slenderness with simply supported edges and subjected to uniaxial compression are studied using the finite element method. Different perforation patterns are investigated, from a single circular hole to 25 circular holes distributed over the plate. A...

Thermal gradients often occur in fire exposed structures. This paper considers thermal gradients over the cross-section of steel columns. By means of finite element simulations, the paper demonstrates that these gradients reduce the fiexural buckling resistance of the columns. This is due to the eccentricity in the column created by the...

This article presents both an experimental as well as a theoretical study on the effect of MethylHy droxyEthylCellulose (MHEC) on drying in porous materials using Nuclear Magnetic Resonance Imaging (NMR). MHEC, a water soluble polymer, is normally added to glue mortars as a water retention agent in order to improve the drying by increasing...

Chloride induced reinforcement corrosion is increasing due to aging of concrete infra structure. Conventional repairs have poor durability and many fail after less than 10 years. For conven tional repair chloride contaminated concrete is removed, steel is cleaned and new concrete is applied. Leaving chiorides, eg. in pits, corrosion may re...

De Oude Kerk in Delft (fig. 112) gaat terug tot 1246 en was oorspronkelijk gebouwd in vulkanisch tufsteen uit de Eifel. Later zijn twee zijbeuken en koor toegevoegd. De westelijke toren werd gebouwd tussen 1325 en 1350. In de l4 eeuw werden de zijbeuken verhoogd tot dezelfde hoogte als het schip, dat zelf in de eerste helft van de 15’ eeuw...

The development of nanomaterials is growing exponentially in the last decade. New discoveries and their applications have taken place in different fields, such as electronics, chemistry, biology and physics. Some innovative nanoproducts have become available also for the conservation of cultural heritage (e.g. nano-Ca(OH)2, nano-SiO2, nano-TiO2,...

Alkali-Silica Reaction (ASR) is a durability problem that affects numerous concrete structures woridwide. As the reaction progresses. it might lead to deleterious expansion and cracking. The addition of lithium into fresh concrete is already acknowledged as a preventive method. In existing structures, however, lithium would need to be driven...

tThe application of new consolidating products on the surface of weathered materials is a common inter-vention technique in conservation practice. Due to the difficulty of producing artificially weatheredsubstrates in a reproducible way, the effect of consolidating products in laboratory is generally assessedon sound substrates. However, the...

Secondary resources containing (catcium) atuminium-silicate phases, e.g., fly ash, slag or bottom ash are used as precursor for binders such as geopolymers. Because secondary resources can be highly variable in terms of their potential to dissolve and form reaction products, analytical methods are needed to evaluate their potential as a...
