    摘要： Methods for producing construction material utilizing loose pieces of aggregate (30), enzyme producing bacteria, an amount of urea and an amount of calcium ions. A first solution is prepared which includes urease which is formed by enzyme producing bacteria. A second solution is prepared which includes urea and calcium ions. The first and second solutions are added to the loose aggregate (30). The calcium ions contribute to the formation of calcium carbonate wherein the calcium carbonate fills and bonds between at least some of the gaps between the loose pieces of aggregate forming a solid construction material (92).

    摘要： The invention relates generally to a cement or gypsum composition having improved properties, which is prepared by incorporating an enzyme into a cement material such as a cement, mortar, or concrete, or into a gypsum product. The invention also relates to methods of manufacturing improved cement compositions and gypsum products, methods of improving the compressive strength of cement compositions and gypsum products, and methods of reducing the cost of such compositions by enabling the use of less expensive aggregates in the manufacturing process. More specifically, the invention relates to a cement composition or a gypsum composition, optionally including at least one aggregate and optionally including at least one pozzolan, comprising a cement material or gypsum optionally including aggregate(s) and pozzolan(s) having blended therein an enzyme.

    摘要： The invention aims to provide a civil engineering material effective to suppress heat island phenomenon in urban cities, develop environments matching with the ambient environments of a construction site, and carry out greening of a desert as well as excellent in washing out resistance and/or planting suitability depending on the objects (or purposes) of the civil engineering works and to provide a construction method of the material. The civil engineering material comprises 10 to 40% by weight of water on the basis of extrapolation amount added to a mixture, which includes 0.5 to 10.0% by weight of cement and 90.0 to 99.5% by weight of an aggregate powder containing fine powder with 0.1 mm size or smaller in 10 to less than 50% by weight. In this case, a coloring material and seeds of plants may be previously added.
