Objetivo A) To develop predictive models of susceptibility to sea-salts for stone materials of different origins (magmatic, metamorphic and sedimentary), at different distances from the sea and at different altitudes. B) To develop a combined non-destructive technique through ultrasonic pulses and picture processing for the automatic processing maps of the textural characteristics of the stones and of their decay patterns for damage evaluation.The project will deeply examine the sea-salt deposition as a function of distance from the sea, altitude, morphology of the coast and wind force. To establish a catalogue of susceptibility to decay for the different types of stone taken from monuments (located differently in terms of the distance from the sea and altitude) the sampling areas of the stone materials on the Atlantic coastal belts of Spain and France and the Mediterranean coasts of Italy and Greece were selected . The research programme includes the following 8 principal functional parts: 1. Environmental conditions and saline rising damp by capillarity action: sea-salt deposition, solution and crystallisation in relation to the altitudes and distance from the sea. Elaboration of a general model to predict sea-salt concentration. 2. Chemical and microanalysis on weathered stone materials. Total soluble salts, ions determination, salt concentration profile and micro-distribution with the stone. 3. Accelerated simulation tests on weathered, quarry and treated stones samples. Design and optimisation of ageing tests simulating the sea-salt decay mechanisms. 4. Petrographic, textural and physical characteristics. Mechanical tests on stone materials. Modulus of compressibility measurements, bending strength and abrasive tests. 5. Porous and/or microfactured stones systems investigation. Porosity and pores size distribution measurements. Geometric model of porous and/or microfractured stone system. 6. Physico-chemical modelling of sea-salt effects. Evaluation of stone susceptibility to sea-salt. 7. Decay patterns and damage evaluation by means of non-destructive techniques. 8. Stone decay maps of textural characteristics of stone materials and processed maps for the evaluation of the surface forms of weathering, thicknesses of decay layers and damage levels.
