HIGH ON THE STRENGTH SEAL INORGANIC POLYMER MORTAR AND IT'S MANUFACTURE METHOD WITH CROSS SECTIONAL REPAIR OF A REINFORCEMENT CONCRETE STRUCTURE OLD PART, AND THE CLASS FORMATION FOR WATERPROOFING

摘要

An inorganic polymer mortar composition having a rapidly class formation for waterproofing and a reinforcement of a concrete structure and a manufacturing method thereof are provided to improve compatibility between the mortar and the applied part of the structure made of cement and to strengthen durability of the site under the construction. An inorganic polymer mortar An inorganic polymer mortar composition having a rapidly class formation for waterproofing and a reinforcement of a concrete structure comprises cement, water, fine aggregate and admixing agent, in which the cement is high early strength Portland cement in the amount of 100 parts by weight, water is in the amount of 35-60 parts by weight, the fine aggregate is in the amount of 40-150 parts by weight which is selected from natural sand, silica sand or mixture thereof, and the admixing agent is in the amount of 10-40 parts by weight. A manufacturing method of the mortar comprises mixing 40-150 parts by weight of the fine aggregates and 10-40 parts by weight of the admixing agent with respect to 100 parts by weight of high early strength Portland cement followed by adding 35-60 parts by weight of water. The admixing agent comprises 1.5-5.0 parts by weight of inorganic expansive, 0.5-4 parts by weight of shrinkage reducing admixing agent, 1.0-4.0 parts by weight of fluidizer, 4.0-10.0 parts by weight of thickening agent, 0.6-1.0 parts by weight of anti-foaming agent, 2.0-8.0 parts by weight of re-emulsification type polymer resin, 1.0-1.7 parts by weight of reinforced fiber and 4.0-10.0 parts by weight of spherical thixotropic agent. The expansive comprises calcium sulfo aluminate(CSA). The shrinkage reducing admixing agent comprises 45-55% by weight of fly ash, 2-5% by weight of anhydrite, 15-25% by weight of limestone powder and 10-25% by weight of blast furnace slag. The fluidizer comprises one selected from lignin, melamin, naphthalic and carboxylic ones. The anti-foaming agent comprises hydrocarbon polyglycols, and the re-emulsification type polymer resin comprises ethylvinylacetate powder resin or SBR powder resin. The reinforced fiber comprises cellulose or polypropylene components, and the spherical thixotropic agent comprises combinations of 2-4 items selected from citric acid, sodium gluconate, tartaric acid, fluosilicate salt, methyl cellulose, ethyl cellulose, boric acid and aluminum powder.
