T1 - Earth block masonry, rammed earth and cob: earthen components from different construction techniques and their structural performance N2 - Both in developed and developing countries, modern building materials tend to be preferred to traditional earthen construction. Reasons include low durability, inadequate performance under seismic loading and, in developing countries, a wish to replace what is perceived as 'poor' with what is perceived as 'rich'. In an age when building permissions and construction standards are a must, particularly in seismic areas, even when an owner is willing to build in earth, construction approval needs to be granted: we rely on values and standards to build, but the necessary data on material properties and structural performance of earthen building techniques is scarce if compared to the abundance of data for other materials (clay brick masonry, concrete, steel) available to the engineer. At the same time, traditional builders' skills, knowledge and confidence in earthen building techniques are decreasing if not disappearing. A wallette testing campaign was thus carried out with the aim of filling this knowledge gap. Prior to the wallette campaign, material properties, including composition and physical-mechanical parameters, were determined. Compression and diagonal compression (shear) tests were then performed, and a basic analysis of the mechanical behaviour of structural elements built in cob is provided in relation to earth block (adobe) masonry and rammed earth elements. Cob, shown to have low compressive resistance, has a relatively ductile post-peak behaviour if compared to earth block masonry specimens which, as expected, show a marked brittle behaviour. In terms of shear strength, cob performs relatively well in view of its low compressive strength. The study is part of our work within the framework of the ongoing project NIKER funded by the European Commission dealing with improving the structural performance of Cultural Heritage assets in order to limit earthquake hazards.

T1 - A new grouting material for the repair of cracks in earthen structures N2 - Traditional earthen structures of cultural value are often damaged by static or dynamic loads. This is usually manifested by the appearance of cracks. All too often these cracks are insufficiently or inappropriately repaired if at all because of lack of knowledge and/or technology. In particular, the behavior of crack repair by grouting poses a challenge in earthen materials and demands specific requirements for the grouting mortar, such as low water content, good water retention, low shrinkage, etc. If dynamic loads, e.g. induced by earthquakes, are expected, the grouting material requires additional specifications such as a compatible strength and modulus of elasticity as well as good adhesion to the earthen materials. The study presents results from the development of a grouting material based on hydraulic lime mortar suitable for the repair of cracks in a variety of earthen building techniques. The goal was to develop a material also compatible with earthen structures exposed to dynamic load. The grouting mortar was designed to be adaptable in strength properties and at the same time to have sufficient robustness for the use on the construction site. First results show a satisfactory performance of the grout concerning fresh and hardened mortar properties as well as injectability. The study is part of our work in the framework of the ongoing project NIKER, funded by the European Commission dealing with improving imovable Cultural Heritage assets against the risk of earthquakes.

A1 - Meng, Birgit T1 - Precast concrete facade elements with low embodied energy N2 - Concrete is by far the most common building material in the world. Due to its good durability it is widely used in building envelopes. One major part of the embodied energy in concrete comes from the production of Portland cement that consumes around 3,500 MJ energy per each ton of cement. Globally 2.6 billion tons of Portland cement is produced and the consumption is increasing. Since concrete will be used as main building material also in future construction, it is reasonable to develop concrete building components with lower embodied energy.Using the example of an ultra-high performance concrete (UHPC) façade element, it is demonstrated how the embodied energy can be reduced by application of hydrothermal curing.

Since on the European market Portland cement does not play the dominant role anymore and due to the new national and European policies concerning Greenhouse Gases and sustainability, cement manufacturers produce more and more blended cements (CEM II–CEM V). Nevertheless, the majority of experience concerning the efficacy of water repellents is gained from Portland cement; therefore knowledge in regard to the interactions of blended cement with water repellent agent is minimal. Two silane-based products were applied on 'fresh' and carbonated cement substrates containing limestone, fly ash, slag and trass, and were investigated in terms of their functionality. The evaluation of the treatments' performance and effectiveness were assessed using various laboratory measurements. Hydrophobicity, water absorption, colour changes and the penetration depth of silanes into the substrate were evaluated before and after artificial aging experiments. Moreover, the outdoor weathering test was performed to shed light on treated surface appearance in a 'real' outdoor environment. The results showed that surface wettability was independent on water ingress or colour variations, especially for cement specimens artificially aged by accelerated carbonation. Cement pastes containing slag and trass seemed to more distinctly affect the water repellents' surface performance.

T1 - Sustainability in the maintenance and protection of architectural surfaces: Innovative water-repellent pozzolana-lime mortars N2 - Water-repellent renders were studied in order to evaluate their suitability for restoration applications. Water repellent admixtures, such as powdered siloxane-based products and metal soaps (zinc and calcium stearates), were mixed with a pozzolana-lime binder similar to historical binders with hydraulic properties. The chemical-physical and structural properties, the effectiveness and the durability of the water-repellent mortars in different environmental conditions were studied. The influence of the water repellent admixtures was evaluated by FT-IR analyses, by testing the mechanical properties and the behaviour in presence of water. The durability of the water-repellent mortars was evaluated after the exposure to artificial weathering (UV-light and water) and to immersion/drying cycles in saturated sodium sulphate solution. The nature of the water-repellent admixtures influenced both the hydration reactions and the chemical-physical properties of the mortars resulting in different resistance to the weathering and to salt crystallization.

T1 - Durability of field concrete made of Portland cement and supplementary cementitious materials under several European exposure conditions N2 - Deterioration of cementitious materials by sulfate ions is a concern for concrete in contact with ground water (and in a lesser extent sea water) in many parts of Europe, and is an important issue for underground construction identified as a major area for progress in the construction industry. Sulfate resistance relates closely to testing and standardization and therefore to prescriptive approaches. The lack of feed back on the durability of structures made of blended cements makes it difficult to fit these new concretes with existing test methods and performance criteria. This paper concerns the microstructural study of field samples and structures made of blended concretes available across Europe. This concerns several materials exposed to various climate regimes, ranging from Southern to Northern Europe (Spain, Germany, United Kingdom, Denmark and Norway). Complementary techniques such as SEM, micro-XRF, XRD and PIXE are used to evaluate the microstructural performance and stability of the phase assemblage of those blended concretes in the case of sulfate (and chloride in some instances) ingress, compare to pure Portland concrete.

A number of various anti-graffiti agents available on the market are intended to be resistant to graffiti attack or provide a treatment that aids the removal of graffiti. In several European countries the testing of anti-graffiti agents on concrete structures is following the EN 1504-2. This method is not appropriate for the aimed result. The method tests if an anti-graffiti agent damages a concrete structure and focuses on drying index and frost resistance in comparison with untreated samples. The aspects of the efficacy against graffiti attack, other types of dirt and aesthetic changes due to anti-graffiti protection are not evaluated by the present method. Therefore a validation and improvement of the current method is proposed.

The results showed that the cleaning efficacy mainly depends on the porosity of the substrate and the type of AGS. Also, higher surface roughness contributed to a lower cleaning efficacy. The results showed also that concrete panels and cement joints in masonry represented the worst case. The color change of all substrate materials compared to concrete was mostly within acceptable limits. Gloss changes were significant for a number of substrates. In particular, several of the wax-treated low-porosity substrates exceeded the threshold value of 10. The limit of water vapor permeability of the AGS prescribed in the TP-AGS might be too high for natural stone substrates. In general, the TP-AGS is useful for the determination of the efficiency factor of anti-graffiti agents on various substrates.

Son muchos los factores que influyen de manera decisiva en el comportamiento de las piedras naturales ante los contaminantes gaseosos. Dos de esos factores son la composición de la atmósfera y el tipo de piedra. Las areniscas en particular son propensas al ataque de los contaminantes atmosféricos debido a su naturaleza porosa, pero muchas de las reacciones de las areniscas no carbonatadas con estos gases no se conocen bien. El estudio presentado tiene por objeto comprender los procesos y factores que controlan el distinto comportamiento de las areniscas respecto al dióxido de azufre. Para el estudio se investigaron siete areniscas distintas procedentes del sur y del este de Alemania. Las areniscas mostraban una diferencia significativa en la composición de su aglomerado. Por lo que respecta a la absorción de SO2, las distintas variedades de arenisca mostraron un comportamiento completamente diferente. Curiosamente, la cantidad de SO2 depositada no estaba relacionada con la superficie específica de las areniscas, este parámetro está relacionado con el contenido en óxidos de hierro. Air pollutants often accelerate stone deterioration in historical buildings and monuments in urban areas. Many factors condition natural stone behaviour with respect to gaseous pollutants. Two of the more prominent of such factors are the composition of the atmosphere and the type of stone. Due to their porosity, sandstones are particularly vulnerable to air pollutant attack. Many of the reactions between noncarbonaceous sandstones and these gases are not well understood, however. The present study aimed to acquire an understanding of the processes and factors governing sandstone behaviour when exposed to sulphur dioxide. Seven different sandstones from southern and eastern Germany were analyzed for the study. The binder composition of the stones varied significantly. They also exhibited completely different behaviour in connection with SO2 deposition. Interestingly, while the amount of SO2 deposited was unrelated to the specific surface area of the sandstones, this parameter was closely correlated to the iron oxide content.
