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.

Compositions and methods for producing materials for construction and for dust control utilizing enzyme producing cells, an amount of a nitrogen source such as urea, and an amount of calcium such as calcium chloride. Calcium contributes to the formation of calcium carbonate which creates a solid structure, layer or shield. One or more compositions containing components of the invention can be sprayed or otherwise applied to surfaces for erosion control, foundation support, prevention of sink hole formation, prevention of dust formation, or other applications. Ammonia, water and other by-products of the process can be recycled and re-utilized for the same or other purposes including, for example, as fertilizers and energy sources, or independently fermented from selectively cultivated microorganisms.

A method of producing a material. The material is produced by the steps of: providing a geopolymer mixture or solution comprising an aluminosilicate and an alkali material; allowing the geopolymer mixture or solution to partially set to form an at least partially set geopolymer including pore spaces; and exposing the at least partially set geopolymer to a metal silicate solution or mixture containing a metal silicate to allow the metal silicate to enter the pore spaces and react to form additional material within the pore spaces. The material may be used in well-cementing and as an abandonment plug.
