HIGH-EARLY-STRENGTH MACROFIBER POLYMER MODIFIED CONCRETE COMPOSITION WITH EXCELLENT CRACK RESISTANCE AND WATER TIGHTNESS, AND CONSTRUCTING METHOD OF PAVEMENT USING THAT

摘要

The present invention is a polymer modified concrete pavement construction using this composition and method, in which the cement binder from 5 to 23% by weight, 32 to 45% by weight of fine aggregate, coarse aggregate, 28 to 44 wt%, 1 to 7% by weight of water, polymer emulsion 0.1 to 5% by weight, 0.1-2 % by weight of the macro fiber, 0.1 to 3% by weight of a water reducing agent as an admixture, wherein the cement binder is a cement steel of 50 to 80% by weight, of calcium aluminate of 0.1 to 40% by weight of sulfo, plaster 1 to 15% by weight, 0.1 to 5% by weight of an alkali silicate composition which is excellent in crack resistance fret steel watertight concrete composition and a polymer -modified fiber macro pavement construction using this method. according to the present invention, the cement binding agent in the polymer emulsion and Macro mix the proper amount of fiber concrete has excellent crack resistance and stiffness of Joe, the construction period is greatly shortened, and have improved water tightness, improved physical properties, as well as various basic field macro placed in continuous fiber supply to the connected mixer materials used for the continuous installation of each mixer can be supplied uniformly to a continuous, on-site production and laying of the concrete finishing process such as a serial number, and seek to the continuity, workability is improved, and a constant quality can be assured.
