摘要： PURPOSE: An acid-resistant section restoring mortar composition using activated silica and a cross section repairing method using the same are provided to enhance acid resistance of hardened cement structure. CONSTITUTION: An acid-resistant section restoring mortar composition(40) using activated silica comprises 10-30 wt% of Portland cement, 1-5 wt% of expansion material, 5-20 wt% of silica fume, 5-20 wt% of blast furnace slag powder, 3-15 wt% of fly ash, 1-5 wt% revival stake polymer powder, 10-30 wt% of bottom ash, 20-40 wt% of sand, 0.01-0.5 wt% of fiber, 0.01-0.5 wt% of thickening agent, 0.01-0.5 wt% of water reducing agent and 0.01-0.5 wt% of antifoaming agent. The bottom ash is dried bottom ash without containing salinity. The bottom ash has the particle size of 4mm or less, the true specific gravity of 2.0-2.5, and the porosity of 45-55%. The silica fume includes fine particle having the particle size of 200,000cm^2/g and the silica content of 90% or greater. The blast furnace slag powder comprises the particle of 4,000-5,000cm^2/g. The expansion material is CSA (Calcium Sulfoaluminate) based k-type expansion material.
