MORTAR COMPOSITION FOR REPARING AND REINFORCING CONCRETE STRUCTURE USING ACID RESISTANT MICROORGANISM AND HIGH-SULFATE CEMENT AND METHOD FOR REPARING AND REINFORCING CONCRETE STRUCTURE
The technology relates to a mortar composition for repairing and reinforcing a concrete structure and a construction method using the same. The composition comprises: a base composition including 40.0 to 51.0% by weight of high sulfate cement, 0.4 to 6.0% by weight of calcium oxide, 0.5 to 2.0% by weight of calcium aluminate cement, 1.0 to 2.0% by weight of calcined magnesium, 1.0 to 2.0% by weight of aluminum hydroxide, 0.5 to 2.0% by weight of lithium hydroxide, and 38.0 to 50.0% by weight of silica sand; and 3.0 to 5.0 parts by weight of a microorganism adsorption composite based on 100 parts by weight of the base composition, wherein the microorganism adsorption composite contains acid-resistant microorganisms adsorbed on an adsorbent. Accordingly, the construction can be done effectively even underwater.
