   Environmental monitoring and rock-property investigations are performed to explain the mechanism of deterioration observed at two buildings constructed in the medieval age and the modern age at Orval Abbey (Belgium). The medieval building is composed of two limestones, while the modern building is composed of reconstituted stone agglutinated using cement containing crushed natural limestones. Deterioration due to salt efflorescence is observed only at the ground floor wall of the modern building. Four measuring sites are set up at these buildings to monitor air temperature and relative humidity. Moisture content and Equotip hardness are measured on a wall at each site. Salt at each site, soils around buildings, underground river water, and three types of stone are also sampled for further laboratory investigation. From the XRD analysis, only calcite (CaCO₃) is detected from salts at sites of the medieval building, whereas calcite, thenardite (Na₂SO₄), mirabilite (Na₂SO₄·10H₂O), and gypsum (CaSO₄·2H₂O) are detected at sites of the modern building. The source of Na and S in these salts is underground river water, not the reconstituted stone. Therefore, crystallization of sodium sulfates from constituents of the river water is considered to be the main cause of the deterioration of the modern building wall.

• An Experimental Study on Strength Deterioration of Cement Mortars by Wetting-Drying Cycles in Sodium Sulfate Aqueous Solution : Equotip hardness and unconfined compressive strength properties

  To evaluate durability of high early strength Portland cement (HES) and alumina cement (AL) mortars for sulfate attack, wetting-drying experiment was carried out. The cylindrical specimens with a size of 35 mm in diameter and 70 mm in height and seawater and saturated sodium sulfate solution at 20°C were used for the experiments. Immersion at 20°C for 2 hours, oven-drying at 40°C for 20 hours, cooling at 20°C for 2 hours, and these wetting-drying procedures were repeated for up to 35 cycles. Equotip hardness and unconfined compressive strength (UCS) of specimens were tested at intervals of several cycles. UCS of specimen decreased at first, which was followed by the drop in surface hardness to a lower value. Decrease of UCS in both mortals was attributed to sub-efflorescence (salt crystallization beneath the surface), and apparent reduction of surface hardness in HES was caused by counter scaling with efflorescence (salt crystallization at the surface). The HES mortal with many micropores (< 0.1 μm in radius) highly deteriorated rather than AL mortal which has pores larger than 0.1 μm in radius. Physical and chemical properties of mortals were due to the induction of sodium sulfate attack, which was attributed to the strength reduction of its own.

  This study aims to elucidate the alteration mechanism of mortar surface reacted with seawater and the relationship between characteristics of secondary products on the surface and salt concentration of seawater. The experiment was carried out in closed system using two kinds of mortars which were made from high-early-strength portland cement (HES) or alumina cement (AL) and silica sand, and two kinds of artificial seawater with half or twice of salt concentrations. Tablet type specimen (3.5-cm diameter, 1.0-cm height) was treated with seawater of 200.0 mL during 20 days. Results of the experiment showed that white products were crystallized on the surface of a tablet in each case. The products were characterized using SEM and XRD. In HES, petal shaped brucite, Mg(OH)_2, was produced by the reaction of portlandite, Ca(OH)_2, with Mg component in seawater. In AL, needle or column shaped aragonite, CaCO_3, was formed. Under high salt concentration of seawater crystalline size of brucite is relatively large in HES, production of aragonite are promoted.

• Changes in Rock Properties of Porous Rhyolite through 40,000 Years in Kozu-shima Island, Japan

  In an attempt to explore the mechanism for rock weathering, temporal changes in various kinds of rock properties due to weathering were investigated selecting Kozu-shima, a small island in the Pacif-ic, as the study site (Fig. 1). In this island four lava domes formed successively with eruption of rhyo-lite, at 1, 100, 2, 600, 20, 000 and 40, 000 y BP (Table 1). These four rhyolites with different ages are de-noted here as the 1.1-ka, 2.6-ka, 20-ka and 40-ka rocks, respectively. It was found in preliminary analy-ses that all four are biotite rhyolite, with (1) a mineral composition of about 85-90% glassy ground-mass and about 10-15% phenocrysts such as quartz, plagioclase, and biotite (Photo 2); (2) a chemi-cal composition of 74-77% SiO₂ and 12-13% Al₂O₃ content (Table 2); and (3) a porosity of about 30% (Table 3). These findings suggest that the rocks had similar original properties when the lava domes formed.
  The following field evidence is recognized. (1) The rocks show little change in lithofacies with in-creasing depth from the ground surface on each outcrop of quarries having a height of 10-20m: no common weathering profile has developed (Photo 1). (2) Schmidt hammer rebound values do not vary with depth on each outcrop (Fig. 2). These observations lead to the first conclusion, that the porous rhyolite has characteristics of so-called “deep weathering”. This high susceptibility to weathering seems to be due to rapid extension of water-rock interaction to the deeper zone, which is facilitated by the presence of (1) a large number of cooling joints with the vertical and horizontal surfaces in a rock mass and (2) a high porosity in a rock block, say, about 30 %, both yielding high permeability in rhyolite.
  Deep and uniform weathering in each lava dome indicates that the present-day rock properties can be assumed to represent the degree of weathering in the time elapsed from each eruption. Rock block samples taken from the outcrop in each dome are analyzed in detail in the laboratory. Minera-logical characteristics of the four rocks were investigated: (1) X-ray diffraction analyses show that clay minerals such as kaolinite and mica clay minerals are formed in older rocks such as the 20-ka and 40-ka rocks (Fig. 3); and (2) SENT photographs show that flow structure in the glassy groundmass is clear in younger rocks such as the 1.1-ka and 2.6-ka rocks, but unclear in the older rocks (Photos 5 and 6) . Chemical composition obtained by X-ray fluorescence analysis and thermo-gravimetry indicates that the amounts of SiO₂, Na₂O, and K₂O decrease slightly in the younger rocks and decrease rapidly in the older rocks, while those of H2_O and FeO^* (FeO+Fe₂O₃) increase slightly in the younger rocks and rapidly in the older rocks (Fig. 5). The SiO₂/Al₂O₃ ratio gradually de-creases in the older rocks (Fig. 6). High leaching of SiO₂ suggests that the solution percolating through the rock mass and block has a high pH. This is supported by the fact that Kozu-shima has been located in the humid and warm environment through the late Quaternary.
