The present invention relates to a lightweight composite material having a binder and at least one first and at least one second filler, the first filler having a density of >2 kg/l and a Mohs hardness of >4 and the second filler having a bulk density of <2.5 kg/l. The concentration of the first filler in the composite material decreases starting from a first surface of the composite material in the direction of an opposite second surface of the composite material. In addition, the invention relates to a method for producing a composite material. This method includes the steps of providing a first filler which has a density of >2 kg/l and a Mohs hardness of >4, and providing a second filler which differs from the first filler and has a bulk density of <2.5 kg/l, and setting a concentration of the first filler in the resin that decreases in the vertical direction from a base surface of the casting mould by utilising the different mobilities of the filler particles in the resin.

Roofing substrates, including shingles, provide for protection of the structure it is covering as well as aesthetics. Shingles come in various types including asphalt, clay, and metal. The shingles may have a dry polymer modified cement mixture applied on top of current shingles or may be used to replace certain layers of, for example, asphalt shingles. The dry polymer modified cement may be applied before or after installation. The dry polymer modified cement may be colored to provide desired aesthetics and lower absorption of the sun's radiation (e.g., visible spectrum, infrared spectrum). The dry polymer modified cement may add minimum weight to the shingles while providing protection to the underlying substrate from environmental deterioration and weathering, thus increasing life of the shingle. The dry polymer modified cement mixture is prepared by mixing a dry polymer modified cement blend (ordinary Portland cement, aggregate and polymer powders) with water.

The invention is directed to compositions and methods for the manufacture of pigmented solids structures for which can be used for construction and/or decoration. Manufacturing comprises fixing one or more pigments to an aggregate material such as crushed rock, stone or sand. The pigmented aggregate is incubated with urease or urease producing microorganisms, an amount of a nitrogen source such as urea, and an amount of calcium source such as calcium chloride forming calcite bridges between particles of aggregate. The resulting solid has a hardness and colorfastness for most any construction material. Using selected aggregate and pigment, the process also provides for the manufacture of simulated-stone materials such as clay or granite bricks or blocks, marble counter-tops, and more. The invention is also directed to composition containing microorganisms and pigment as kits that can be added to most any aggregate materials.
