“…In this line, the calcarenites cemented by smaller calcite grains and with higher pore size (BC-Y1 and BC-Y2) exhibit greater strength reductions due to water saturation than the varieties cemented by greater calcite grains and with lower pore diameters (BC-BL, BC-BG and BC-DM). These results are in agreement with those found by Török [49], Papay and Török [50] and Török and Szemerey-Kiss [51], [52], who observed that the limestones cemented by fine grained micrite calcite are more water sensitive in terms of strength and durability than those cemented by micro-sparitic calcite. In addition, they also found the existence of a close relationship between the pore structures and the mechanical properties of Hungarian limestones.…”

Stone construction elements are frequently in moist environments or in direct contact with water. Design and test standards have traditionally ignored the water impact on rock materials. However, several studies have shown that moisture can cause drastic strength reductions and deformability increase in some sedimentary rocks. For that reason, the main objectives of this work are: a) to quantify and understand the influence of water saturation on strength and deformability of four porous calcarenite building stones widely used in SE Spain ; b) to establish correlations between physical and mechanical properties of these rock materials in dry and saturated states and c) to compare the results with previous findings. The results showed a very significant reduction of mechanical properties such as unconfined compressive strength, Young´s modulus and point load strength index when these stones undergo saturated. In addition, significant correlations between physical properties (density, porosity, P wave velocity and dynamic elastic parameters) and the mentioned mechanical properties were established in dry and saturated conditions. Additionally, relationships among the mechanical properties of stones in both states are also proposed.

“…The micro-fabric, micro-cracks (Freire-Lista et al 2015), pore sizes and the interconnections of pores significantly influence the durability and weathering properties of rocks (Tuğrul 2004;Török 2006;Yu and Oguchi 2010;Přikryl 2013;Pápay and Török 2015) mineralogy controls the salt crystallisation durability and micro-Deval coefficient of the studied andesites, too. Explicitly, Andesite-2 and Andesite-3 have similar micro-fabric, but the slicification of Andesite-2 resulted in higher resistance against salt crystallisation and lower micro-Deval coefficient ( Fig.…”

The durability of aggregates against salt weathering is calculated after five cycles of immersion in a magnesium sulfate solution followed by drying according to the relevant European standard (EN 1367-2: 2010). The aim of the study is to investigate the long-term durability of aggregates by increasing the number of cycles of the salt crystallization test from the standardized five to a maximum of 35. Three andesite types from Hungarian quarries were tested representing three different localities. The weight loss of the specimens was determined after every 5-cycle set. Results were documented for three size-fractions 10.0/11.2 mm, 11.2/ 14.0 mm and the 10.0/14.0 mm, respectively. Relationships between immersion-drying cycles and magnesium sulfate values were described by the Pearson-coefficient. According to the test results, the magnesium sulfate values followed linearly increasing tendencies in the course of the long-term salt crystallization tests. Parallel to the salt-weathering tests, the changes in the mechanical properties of the salt-attacked aggregates were also detected by micro-Deval tests (EN 1097-1: 2012). The changes in micro-Deval coefficients were calculated in the form of a decay factor as a function of sulfate cycles. The results suggest that the micro-Deval coefficient does not rise after a certain salt cycle; i.e. higher number of salt-crystallisation cycles does not necessarily reduce the micro-Deval coefficient of studied andesite lithologies.
