Disclosed is settlement substrate for oyster technology, and, in particular, the present disclosure relates to a concrete settlement substrate for oyster and a preparation method thereof, and a construction method. The concrete settlement substrate for oyster has the characteristics of induction of rapid settlement and metamorphosis of sessile organisms thereto, promotion of long-term growth and good durability, and the oysters are settled on a surface of concrete. A reasonable spatial layout is utilized, such that each concrete pile (block) can effectively break waves and ensure smooth exchange between water bodies on two sides. After oysters settled to each concrete pile (block) breed a large amount, the water bodies can be purified, and the ecological environment in the surrounding sea area can be improved.

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.
