A superhydrophobic asphalt and a method of its preparation. The superhydrophobic asphalt contains an asphalt layer containing a polymer modified asphalt, preferably a radial SBS modified asphalt, and a polypropylene layer. The polypropylene layer comprises granules of polypropylene thermally fused to the asphalt layer. The superhydrophobic asphalt has a water contact angle of 145 to 170°, above the classification threshold for superhydrophobicity. The method of preparing the superhydrophobic asphalt involves distributing polypropylene granules over the surface of a polymer modified asphalt and curing below the melting temperature of the polypropylene. The asphalt may find use in waterproofing applications such as roofing.

A process for the preparation of a concrete structure including casting a layer of concrete, application of a waterbased curable resin system on the wet cast concrete layer and subsequently mechanical incorporation of the waterbased curable resin system into the concrete layer. The mechanical incorporation of the waterbased curable resin system into the concrete layer, which can advantageously be combined with trowelling of the cast concrete surface, the adhesion of a subsequent applied coating onto the thus treated concrete layer is significantly improved particularly in relation to peel strength. Further, a coated structure prepared by this process, which is particularly a floor.

Methods for embedding photocatalytic titanium dioxide in asphalt surfaces to reduce pollutants via photocatalytic reactions are provided herein. One method includes applying an amount of an asphalt surface treatment compound to an upper surface of the asphalt surface, the asphalt surface treatment compound including a mixture of a liquid carrier compound with a titanium dioxide (TiO.sub.2) photocatalyst.

Disclosed are a semi-transparent ceramic sheet decorated through ink light-absorbance and a preparation method thereof. The semi-transparent ceramic sheet comprises a semi-transparent green body, an inner inkjet pattern layer infiltrating into the semi-transparent green body from an upper surface of the semi-transparent green body, a decoloration glaze layer located on the upper surface, and a surface pattern layer located on the decoloration glaze layer. The decoloration glaze layer is capable of decoloring the ink of the inner inkjet pattern layer. The semi-transparent ceramic sheet is provided with the decoloration glaze layer so that the inkjet decoration of the inner inkjet pattern layer cannot be displayed on the surface, and the decorative pattern on the surface of the green body is the surface pattern layer and the inner inkjet pattern layer is completely in the inner layer of the green body.

Sintered technical ceramic based on zirconia ZrO2, characterised in that it comprises: less than or equal to 3.6 wt % and greater than or equal to 2.5 wt % of yttrium oxide Y2O3; at least one complementary component from hafnium oxide HfO2, alumina Al2O3, and magnesium oxide MgO; at least one additional element from Fe, Ni, Cr, Zn, Co, Mn, Cu, Ti, Ta, W, Pt, the weight proportion of said at least one additional element being greater than or equal to 0.1 wt %, or greater than or equal to 0.5 wt %, or greater than or equal to 1 wt %, or greater than or equal to 1.5 wt %.
