| titleOfInvention | High performance latex modified quick-hardening cement concrete composition using modified sulfur nano solution and road repairing method using the same |
| abstract | The present invention is a high-performance latex-modified fast-diameter cement concrete composition containing a modified sulfur nano-aqueous solution, 10 to 40% by weight of a fast-diameter binder, 10 to 50% by weight of fine aggregate, 5 to 40% by weight of coarse aggregate, 0.1 to 10% by weight of mixing water % and 0.1 to 10% by weight of a high performance latex modifier; The fast-diameter binder is based on 100 parts by weight of crude Portland cement, calcium sulfoaluminate 20 to 40 parts by weight, anhydrite 10 to 30 parts by weight, sodium aluminate 1 to 10 parts by weight, magnesium fluoride 1 to 10 parts by weight, meta 0.1 to 5 parts by weight of lithium phosphate and 0.1 to 5 parts by weight of citrus peel fibers; The high-performance latex modifier is based on 100 parts by weight of the styrene-ethylene-butylene-styrene (SEBS) block copolymer, 40 to 60 parts by weight of the acrylate-styrene-acrylonitrile copolymer, 1 to 10 parts by weight of the modified sulfur nano-aqueous solution , 1 to 10 parts by weight of ethylene-ethyl acrylate-maleic anhydride copolymer and 0.1 to 5 parts by weight of potassium-perfluorobutane-sulfonate; The reformed sulfur nano-aqueous solution is mixed with 1 to 10 parts by weight of an acrylated dicyclopentadiene monomer represented by the following Chemical Formula 1 with respect to 100 parts by weight of the sulfur monomer generated in the crude oil refining process, 150 to 220° C. and 2 to 3 atmospheres reacting to obtain reformed sulfur; 1 to 10% by weight of the modified sulfur, 1 to 10% by weight of an aliphatic polyester-based polymer, and 50 to 80% by volume of an organic phase containing the remaining amount of an organic solvent, and 5 to 30% by weight of an effervescent salt of ammonium (bi) carbonate or sodium carbonate % and 20 to 50% by volume of the first aqueous phase containing distilled water to obtain a uniform W / O emulsion; and mixing the W / O emulsion with a second aqueous phase containing 0.1 to 0.5 wt % of a hydrophilic surfactant and the remaining amount of distilled water in a 1: 10 to 20 volume ratio, emulsifying, and then electrolyzing. by using those manufactured by; A modified sulfur nano-aqueous solution that can satisfy the required performance (structural performance, workability, etc.) as a cement concrete composition and can extend the durability of the structure due to its excellent resistance to chemical, freeze-thaw and salt damage in particular It relates to a high-performance latex-modified fast-diameter cement concrete composition and a road pavement repair construction method using the same. [Formula 1] In the above formula, R 1 is H or a linear or branched C1 to C4 alkyl group, and n is an integer from 0 to 5. |
