High functional quick-hardening and ultra-early strength type cement concrete composition modified by polymer modifier with diene rubber latex and the construction method for road pavement using the same

摘要

The present invention comprises 10 to 40% by weight of a high-functional 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 polymer modifier; The high-functional binder is based on 100 parts by weight of crude Portland cement, calcium sulfoaluminate 20 to 40 parts by weight, barium aluminosilicate 10 to 30 parts by weight, gypsum 10 to 30 parts by weight, zinc phosphate 1 to 10 parts by weight, polyaniline 0.1 to 5 parts by weight of nanofibers, 0.1 to 5 parts by weight of clinoptilolite, and 0.1 to 5 parts by weight of manganese sulfate; The polymer modifier is based on 100 parts by weight of the acrylic copolymer resin, 50 to 80 parts by weight of bisphenol A epoxy resin, 30 to 60 parts by weight of dimer acid, 10 to 40 parts by weight of diene-based rubber latex, and 1 to 20 parts by weight of a silane coupling agent. to include; The diene-based rubber latex is prepared by polymerizing 60 to 80% by weight of a conjugated diene-based monomer, 10 to 30% by weight of an aromatic vinylic monomer, and 1 to 20% by weight of a vinylcyanic monomer; By promoting the initial hydration of cement and densification of the tissue, it is possible to manufacture tightly sealed concrete, so that the damaged part of the concrete pavement can be repaired quickly, and cracks and expansion destruction caused by the shrinkage of the concrete can be prevented. It relates to a high-functional ultra-fast and crude steel cement concrete composition modified with a polymer modifier containing diene rubber latex that can provide durability such as excellent strength, salt penetration resistance, freeze-thaw resistance and abrasion resistance, and a road pavement construction method using the same .
