A multilevel approach for the damage assessment of Historic masonry towers

In the paper some case studies of damaged towers in Italy are presented: the Tower Masserano of Palace Ferrero - La Marmora at Biella, the bell tower of the Collegiata of San Vittore at Arcisate, and three medieval towers in Alba. A methodology is put forward for combining laboratory and nondestructive testing methods with monitoring systems in order to reach the goal of evaluating the state of conservation of historic towers and its evolution in time.     

Modeling of Light-Induced Changes in Reflectance Spectra: A Predictive Tool for the Effect of an Arbitrary Spectral Irradiance

Optical radiation is capable of altering the spectral reflectance of layers of colorants. Light damage is of particular importance in respect to unique historical objects in exhibitions. The major parameter governing this process is the spectral irradiance applied to the surface. As this may vary significantly for different light sources, an experimental investigation of the damage potential of the numerous illuminants available is a cumbersome task. In this work a numerical algorithm for the prediction of modifications of the spectral reflectance of colorants subject to a given arbitrary spectral irradiance over a given time is presented. It uses the temporal evolution of the spectral reflectance of the dye or pigment at issue when irradiated by a set of narrowband light sources as input data. The predicted reflectance spectra and the resulting color changes are compared to those measured for samples irradiated with common polychromatic light sources. The concept described in this work aims at the implementation of a standardized procedure and database for the prediction of radiative damage for a comprehensive range of pigments and dyes.     

Wall base ventilation system to treat rising damp: The influence of the size of the channels

One of the major causes of pathologies in our historic buildings is the presence of moisture, particularly rising damp. Since these constructions tended to be built near water lines, to facilitate their supply, and because their walls are mainly made of high porosity materials, the presence of rising damp is constant. Although many historic buildings in Portugal have already been the targets of interventions to eliminate pathologies, the fact is that it has not been possible to do it properly. The treatment techniques available nowadays are quite diverse but all of them have low applicability to historic constructions. Research has been carried out, in this past years, at the Department of Civil Engineering of the University of Coimbra in collaboration with Department of Civil Engineering of the Faculty of Engineering of the University of Porto to try and solve this problem. An old but poorly studied technique has been investigated experimentally and numerically in the past few years: ventilation of the base of the walls. It was experimentally validated to limestone walls 20 cm thick. Numerical investigation has been carried out in order to analyze the influence of different parameters on its efficiency. In this paper we present the results of the latest investigations that have been carried out about the influence of the size of the ventilation channel on its efficiency.     

Pore structure of historic and repair Roman cement mortars to establish their compatibility

Mercury porosimetry was applied to the study of pore structure of the historic Roman cement mortars representative of different locations in Europe and time periods as well as different application techniques from architectural castings to in situ formed renders and profiles. Three categories of pores were found to coexist in the mortars. The finest pores, with diameters below 0.1 μm, are present within the hardened aged Roman cement matrix. The larger ‘air’ pores, with diameters between 0.2–2 μm, are due to the evaporation of the excess unbound water and restricted hydration. Pores larger than 2 μm are rare and, in general, can be related to microcracking induced by shrinkage drying and mortar weathering. The mortars have rarely been found to develop a dense fine-porous microstructure characteristic of the ideal conditions of moist-curing; massive architectural castings being the only exception identified. The presence of larger ‘air’ pores was, in turn, almost universally observed. The investigations of the freshly prepared Roman cement mortars have revealed that the restricted hydration could be due to the exposure of the freshly laid surface to dry real-world external environments, a high water-to-cement ratio in the original mortars, or the drawing of water from the stucco mass due to insufficient pre-wetting of the porous masonry. The insufficient reactivity of historic cements, resulting from a high content of over-burned, non-reactive cement components or coarseness of the cement grains, could be another reason for yielding poorly hydrated mortars in the past. In general, Roman cement stuccoes are in an excellent state of preservation in spite of their usual exposure to polluted urban environments for more than a century. Therefore, the coexistence of Roman cement mortars of widely different pore structures has not brought about any problems of incompatibility which field observations could reveal. The Roman cement repair materials have been found to develop pore structures similar to those of historic mortars. Therefore, they are in broad terms compatible with historic masonry or stuccoes. However, the porosity and strength of the repair materials can be controlled by a careful manipulation of the water-to-cement ratio of the mix to adapt them better to the properties of the host material.

生-死“之间”:关于存在者的历史性的存在——源自海德格尔的《阿那克西曼德之箴言》的运思和追问

生-死"之间"意味着存在者向有限的既定的历史性的穿透。在这里,"之间"命名为对操持的承担,呼求着生命的出席,同时还标画着存在者刻画的源始根据所在。运思生-死"之间",不仅是就发生性的开展来把捉存在者向其自身的切近,揭露存在者的存在;而且也是就存在者的切身向死性来领会存在者在场的历史性、有限性,进而以有限性为根据来筹划存在者的持存,从而使得存在者在寻视其命运的通途中得以赢获自身。
