| titleOfInvention | Latex modified rapid hardening cement concrete composition with porous filler having excellent long-term shrinkage reduction and high durability and construction method of pavement surface for bridge deck and road using the same |
| abstract | The present invention provides excellent long-term shrinkage comprising 10 to 30% by weight of a fast-hardening cement binder, 30 to 60% by weight of fine aggregate, 20 to 50% by weight of coarse aggregate, 1 to 20% by weight of a latex modifying admixture, and 1 to 20% by weight of a compounding water A latex-modified fast-hardening cement concrete composition containing a porous filler having reduced performance and high durability, The fast-hardening cement binder is usually 75 to 95 parts by weight of calcium sulfoaluminate having a fineness of 4,500 to 9,000 cm 2 /g and a content of Al 2 O 3 of 32 to 36% by weight based on 100 parts by weight of Portland cement, 45 to 65 parts by weight of hydrofluoric acid gypsum having a fineness of 4,000 to 8,000 cm 2 /g, 10 to 20 parts by weight of slaked lime having a CaO content of 70 to 83% by weight, zeolite, perlite, vermiculite, and mixtures thereof Hydroxy ( 0.1 to 1 part by weight of C1 to C3 alkyl)cellulose; The latex-modifying admixture has a solid content of 47 to 75 wt%, a glass transition temperature (T g ) of -40 to 0 ° C, and a minimum film formation temperature (MFFT) of 0 to 27 ° C. Acrylic emulsion latex, styrene- butadiene latex and at least one emulsion latex selected from the group consisting of mixtures thereof; The latex-modified admixture is used to include an alkyl sulfonated tetrazole compound represented by the following formula (1); Latex-modified fast-hardening cement concrete composition containing porous filler with excellent long-term shrinkage reduction performance and high durability by effectively preventing initial temperature deformation, drying shrinkage and cracks caused by external temperature, and a method for repairing bridges and pavements using the same it's about [Formula 1] In the above formula, R 1 is at least one functional group selected from a linear or branched C1 to C20 aliphatic alkyl group, a C3 to C20 alicyclic alkyl group, a C6 to C20 aryl group, and a mixed functional group thereof, and n is 1 to 6 is the integer of |
