    • The invention provides a process for the production of a cementious material. The process comprises mixing cement starting materials and a particulate healing agent to provide the cementious material. The healing agent comprises coated particles, wherein the coated particles comprise bacterial material and additive. The bacterial material is selected from the group consisting of a bacterium, a lyophilized bacterium and a bacterial spore of a bacterium. The present invention solves these problems, as (substantially leakage-proof) tablets containing the actual healing agent may neither interfere with either the workability of the liquid mixture (“cementious material”) nor negatively affect properties of either mixture or final material (hardened concrete), even when applied in large quantities. During crack formation in cementious based constructions, the particles also crack, and healing agent is released.
    • 本发明提供一种生产胶结材料的方法。 该方法包括混合水泥起始材料和颗粒愈合剂以提供粘结材料。 愈合剂包括涂覆的颗粒,其中涂覆的颗粒包括细菌材料和添加剂。 细菌材料选自细菌,冻干细菌和细菌的细菌孢子。 本发明解决了这些问题,因为含有实际愈合剂的(基本上防漏的)片剂既不会干扰液体混合物(“胶结材料”)的可加工性,也不影响混合物或最终材料(硬化混凝土 ),即使大量应用。 在水泥基结构裂缝形成过程中,颗粒也开裂,释放愈合剂。

    • 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.
    • 本发明一般涉及具有改进性质的水泥或石膏组合物,其通过将酶掺入到诸如水泥,砂浆或混凝土的水泥材料中或制成石膏制品而制备。 本发明还涉及制造改进的水泥组合物和石膏产品的方法,改进水泥组合物和石膏产品的抗压强度的方法,以及通过在制造过程中使用较便宜的聚集体来降低这些组合物的成本的方法。 更具体地说,本发明涉及一种水泥组合物或石膏组合物,其任选地包括至少一种骨料,并且任选地包括至少一种火山灰,其包含任选地包含骨料的水泥材料或石膏,其中混合有一种或多种 酶。
