Function gradient bacterial capsule for concrete self-repairing
Disclosed herein is a capsule that can be incorporated into a cementitious material for repairing cracks in the cementitious material. The capsule may comprise an inorganic particle having a surface and a core region, where the core region contains bacterial spores for repairing the crack, or the core region contains bacterial spores for repairing the crack and the capsule contains a nutrient separate from the bacterial spores, wherein the density and strength of the inorganic particles decrease in a direction from the surface to the core region, and the density at the surface is sufficient to impede permeation of alkaline substances. Disclosed herein is a nutritional capsule that can be incorporated into a cementitious material for containing nutrients that help bacterial spores repair cracks in the cementitious material. A nutritional capsule may include an inorganic particle having a surface and a core region, where the density and strength of the inorganic particle decrease in a direction from the surface to the core region, and the core region contains a nutrient, and the capsule is free of bacterial spores. Disclosed herein is a cementitious material incorporating (i) a capsule or (ii) a capsule and a nutritional capsule. Also disclosed herein are corresponding capsules, nutritional capsules, and methods of forming cementitious materials.
本文公开了一种可掺入水泥基材料中用于修复水泥基材料中的裂纹的胶囊。该胶囊可包含具有表面和核心区域的无机颗粒，其中核心区域容纳用于修复裂纹的细菌孢子，或者核心区域容纳用于修复裂纹的细菌孢子并且胶囊容纳与细菌孢子分开的营养物，其中无机颗粒的密度和强度沿从表面到核心区域的方向减小，并且表面处的密度足以阻碍碱性物质的渗透。本文公开了一种可掺入水泥基材料中用于容纳有助于细菌孢子修复水泥基材料中的裂纹的营养物的营养胶囊。营养胶囊可包括具有表面和核心区域的无机颗粒，其中无机颗粒的密度和强度沿从表面到核心区域的方向减小，并且核心区域容纳营养物，并且胶囊不含细菌孢子。本文公开了一种掺有(i)胶囊或(ii)胶囊和营养胶囊的水泥基材料。本文还公开了相应的胶囊、营养胶囊和水泥基材料的形成方法。
