Bij houten weg- en water bouwconstructies blijft er vaak water staan tussen aansluitingen van constructiedelen. Het vochtgehalte van het hout stijgt, met versnelde materiaaldegradatie tot gevolg. De ontwateringsplaat, een innovatie van TNO, gaat houtrot op verbindingspunten tegen

This paper presents a new formulation of the Rate Type Compaction Model (RTCM) for sandstone based on the isotach concept. The RTCM was originally developed to explain the loading rate dependent compaction behaviour observed in laboratory test on unconsolidated and consolidated sandstone samples and the delayed subsidence behaviour above...

Terwijl de timmerindustrie in Nederland met geavanceerde machines een hoge mate van automatisering bereikt, komt werkelijke innovatie van product en productie niet echt van de grond. TNO en FSC Nederland roepen timmerfabrikanten en hun ketenpartners op om in werksessies los te komen van hoe ze altijd hebben gewerkt. Jan de Jong, projectleider...

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...

The water phases in a MgSO4·7H2O crystal during heating were studied with the help of NMR. The thermogravimetric analysis (TGA) data showed that the heating rate has a strong effect on the dehydration process. NMR experiments showed that pore water, i.e., an aqueous solution of MgSO4, was produced during dehydration. Additional NMR measurements...

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...

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...

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...

Although reinforcement corrosion is a well-known issue, which are the locations of the steel/concrete interface most sensitive to pitting corrosion is still an unclear issue. In this study, X-ray computed tomography is used to characterize eight 20-years-old reinforced concrete cores naturally deteriorated due to chloride-induced corrosion. The...

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...

Fungal growth in the indoor environment can affect human health by causing allergic reactions and respiratory symptoms. In the search for a solution to prevent or limit fungal growth in the indoor environment it is important to know how parameters such as temperature, substrate, and humidity affect fungal growth. Up to now, no general accepted...

Geopolymeren zijn belangrijk voor de 'verduurzaming' van beton. Daar waar Portlandcement als bindmiddel in beton hooguit bijgemengd kan worden met secundaire grondstoffen zoals slak en vliegas, bestaan geopolymeren voornamelijk uit deze of andere secundaire grondstoffen, zonder cement. Dit levert een aantal belangrijke voordelen op: als...
