PATCHING REPAIR MATERIAL AND REPAIRING METHOD OF DETERIORATED REINFORCED CONCRETE STRUCTURES
Disclosed is a composition of a section restoration material to repair a degraded ferroconcrete structure, wherein the composition comprises: 72-75 wt% of cements; 5-8 wt% of silica fume; 7-9 wt% of crystallized glass consisting of 50-55 parts by weight of silicon dioxide, 32-37 parts by weight of alumina, 3-4 parts by weight of potassium oxide, and 1.5-2 parts by weight of ferric oxide; 6-7 wt% of artificial lightweight aggregates; 3-4 wt% of magnesium oxide; 0.2-0.5 wt% of carbon nanotubes; 0.25-1 wt% of sodium silicate; 0.75-1 wt% of expansion agents consisting of 45-55 parts by weight of calcium oxide, 24-28 parts by weight of sulfur trioxide, 10-15 parts by weight alumina, and 1-2 parts by weight of silicon dioxide; 0.2-0.4 wt% of shrinkage reducing agent consisting of 1-40 parts by weight of acrylic polymer compound, 0.5-30 parts by weight of nitrate compound, and 1-50 parts by weight of glucose compound with respect to 100 parts by weight of an aqueous solution consisting of 3-20 wt% of fluorosilicate salt consisting of one of fluorosilicate magnesium and fluorosilicate zinc or a combination thereof, 5-30 wt% of silica, and 70-92 wt% of water; and 0.2-1.5 wt% of anti-rust agent. According to an embodiment of the present invention, the composition for a section restoration material has low thermal conductivity; thereby improving thermal insulating performance, and having a low temperature derivation, thus increasing resistivity for a temperature change and a humidity change.
