  • Microbiologically induced calcite precipitation - Wikipedia

    Microbiologically induced calcium carbonate precipitation (MICP) is a bio-geochemical process that induces calcium carbonate precipitation within the soil matrix. Biomineralization in the form of calcium carbonate precipitation can be traced back to the Precambrian period. Calcium carbonate can be precipitated in three polymorphic forms, which in the order of their usual stabilities are .

    Concrete Mix. An effective concrete mix contains cement, water and fine and coarse aggregates. Portland cement, developed in 1824, is the most common type in construction. A proper mixture must have enough paste to bind the aggregates, otherwise the product will be porous and rough. Concrete with too much paste will be more likely to shrink.
