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.

The invention comprises a concrete form. The concrete form comprises a first panel having a first primary surface for contacting plastic concrete and a second primary surface opposite the first surface, wherein the first panel is made from a rigid plastic sheet or a metal sheet; and a second panel spaced from the second primary surface of the first panel, wherein the second panel is made from a rigid plastic sheet or a metal sheet. The concrete form also comprises a layer of insulating material disposed between the first panel and the second panel. A method of using the concrete form is also disclosed.
