摘要

The present invention relates to an ultra-high-strength aqueous epoxy resin mortar composition that implements radiation shielding, bulletproof, protective and seismic functions, including an environmentally friendly aqueous amine-based curing agent, and a structure installation method using the same, more specifically, a structure wall or a slab installation Installing a formwork for; And pouring an aqueous epoxy resin mortar composition to the formwork to form a wall or slab, wherein the aqueous epoxy resin mortar composition comprises 10-50 parts by weight of epoxy resin, 10-90 parts by weight of water, and 10-10 parts by weight of additives. 100 parts by weight of the epoxy-modified amine compound formed by adducting an active group equivalent of 30 to 60 of the amine active group equivalent 100 of the amine compound with respect to 100 parts by weight of the basic resin made of an aqueous epoxy resin composition comprising 50 parts by weight Based on 200 to 500 parts by weight of water and 30 to 50 parts by weight of a curing component composed of an aqueous amine-based curing agent composition comprising 0.01 to 1.0 parts by weight of montmorillonite nanoparticles, 150 to 150 parts of silica based on 100 parts by weight of the mixed component Using an aqueous epoxy resin mortar composition obtained by mixing 500 parts by weight again, the method of installation and construction of a structure using an aqueous epoxy resin mortar composition, characterized in that it comprises pouring and curing the aqueous epoxy resin mortar composition in a formwork Gives According to the present invention, in forming an aqueous epoxy resin mortar composition, the surface of the amine compound can be replaced with an epoxy compound by up to 60% by forming an adduct by adding an epoxy compound to the amine compound by a stepwise reaction. Since it can effectively reduce the peculiar amine odor in the conventional amine curing agent, and is used by mixing an aqueous epoxy-based component and an aqueous amine-based curing agent component, compatibility is maintained even after adding a large amount of water, up to 5 times Even if a corresponding large amount of water is added, the cured properties can be maintained as it is and the compatibility with the main material can be maintained, so it is excellent in usability and workability, so it has a very convenient application in the field. In addition, the aqueous epoxy resin mortar composition according to the present invention is composed of a main component containing an epoxy resin and an aqueous amine-based curing agent component, and has excellent properties such as compressive strength and tensile strength, and rapid process treatment. By constructing a structure using an aqueous epoxy resin mortar composition having ultra-high strength, it can be used as a structure for radiation shielding, bulletproof and protection by replacing the existing concrete, and also can have a seismic function, so it can be used as a seismic structure. , When installed on dams, docks or piers, it is highly resistant to pressure and shock and has the effect of preventing deterioration.
