On the 23 rd May 2014 fire burnt through the west end of the GSA [2,3,4]. Starting in the basement the fire engulfed several studio spaces, and the School's library; perhaps the finest example of Art Nouveau interior design in the world [1,5]. The public and expert reaction to the disaster [5] has contextualised recovery; research seminars developed collaborative projects around the impact of the fire, from which this project grew. In the devastated library space, damage is evident on the sandstone walls, notably the piers between the windows and the walls either side of the tall windows. Surface spalling and cracking of the stone will require significant intervention as part of the restoration effort. The loss of cultural, historic and artistic value, due to the fire, is indeed tragic, but the damage to the structural fabric of the building also behoves us to understand the material impact of the disaster to assist in the restoration and recovery activities. The purpose of the MOLAB visit was to perform analysis on the affected walls to understand the effects of the fire on the stone and to evaluate the degree of damage. It is hoped this will contribute to decision-support for the repair works. Access to the library for MOLAB was under conditions of a construction site, with appropriate health and safety measures with regard to working practice and personal protection. Structural assessment of the walls of the Macintosh school necessitated the construction of a bracing scaffold. Access was required from floor level up to approximately 4-5m height. Two movable scaffold towers were erected against the fixed scaffold, and permission obtained to place measureing equipment onto the fixed scaffold.
Nueva Tabarca is a small island located in the Mediterranean Sea, close to the city of Alicante (... more Nueva Tabarca is a small island located in the Mediterranean Sea, close to the city of Alicante (SE of Spain). Although the island is mainly known for its marine reserve, its fortified village is an exceptional example of Baroque architectural heritage, mainly built with stone and lime mortars. However, in spite of the singularity of its monuments, the majority of walls and buildings of the old town of Tabarca are in an alarming state of conservation. Airborne salt, Aeolian erosion and anthropic activity are the main causes of decay. Although several restoration works were carried out during the 70’s and in the first decade of the present century, all of them have shown to be ineffective, due to the low durability of the repair materials used. To investigate the causes of such an intense decay of both original and repair mortars, a complete characterisation of these materials has been carried out, by means of both field and laboratory studies that included: diagnosis of the conserva...

The main aim of the project is the development of a multi-scale model for the computer based simulation of mechanical and durability performance of cementitious materials. This paper reports results of nanoindentation testing on fully calcium leached cement paste in relation with the prediction from the latest computer model developed in the CODICE research project. Using the statistical nanoindentation technique, intrinsic properties of different hydrate phases after leaching has been studied. In order to perform reliable nanoindentation experiments a very smooth and flat sample surface is required. Due to the very porous and weak microstructure of fully-leached cement paste resin impregnation has to be used to produce satisfactory and representative specimens for the nanoindentation experiments. Extensive trials with different low stiffness resins (Youn...
