Abstract
A method for producing photocatalytic mortar includes providing a mortar-producing material including a fine aggregate and cement, a reactant mixture including a zinc source and urea, and a microorganism-containing mixture including water and a urease-producing microorganism, subjecting the microorganism-containing mixture and the reactant mixture to microbial induced precipitation in the mortar-producing material, subjecting zinc carbonate crystal-containing mortar produced to curing for the same to undergo hydration, and subjecting cured mortar to hydrothermal synthesis, so that zinc carbonate crystals therein are converted to nano zinc oxide crystals.
