The invention relates to ceramic granules with a high UV opacity and high solar reflectance, which is produced by forming a calcined clay mineral powder into green body and re-calcining, featured with a water absorption of 15-35%; 97% crystalline content and 90-100% UV opacity. The invention further relates to a method for preparing ceramic granules with a high UV opacity and high solar reflectance and the use thereof for reflectance-improving application on building surface for the purpose of energy conservation.

The present disclosure provides an installation structure of a curved tile, including a first curved tile and a second curved tile which each comprises a tile body, wherein both ends of the tile body are respectively a first curved overlapping portion and a second curved overlapping portion, a curved surface of the first curved overlapping portion faces downward, a curved surface of the second curved overlapping portion faces upward, the first curved overlapping portion of the first curved tile overlaps on the second curved overlapping portion of the second curved tile, and a waterproof structure is disposed at a position where the first curved tile overlaps with the second curved tile.

A roof tile comprising a decorative layer having at least a ceramic body, and a support layer disposed below the decorative layer, wherein the roof tile comprises an upper edge, a lower edge which is opposite to the upper edge and two opposite side edges, said side edges being transverse to the upper edge, wherein said roof tile comprises at least one anchoring element for anchoring the roof tile to a structure or framework.

A roofing tile composed of concrete material and a method for producing such a roofing tile. The concrete material contains a binder, a gravel, a light-weight aggregate, and added water. The roofing tile has at least one watercourse and a lateral interlocking joint having a covering fold and a water fold. The ratio of water to binder is less than 0.3, the light-weight aggregate is composed of a material that is hydrophobic and/or not hygroscopic, and the roofing tile has a density in the range of 1.6 g/cm.sup.3 to 1.9 g/cm.sup.3 after the hardening. The roofing tile has a thickness of 5 mm to 9 mm, preferably 7 mm to 8 mm, in the highly loaded regions, preferably in the region of the watercourse.
