Abstract

The invention discloses an energy-saving and environment-friendly high-strength epoxy resin concrete material, and particularly relates to the technical field of build concrete. According to the energy-saving and environment-friendly high-strength epoxy resin concrete material, main materials are prepared from, by weight, 70-100 parts of epoxy resin, 30-40 parts of a basic material, 8-12 parts ofriver sand and 10-15 parts of asbestos fibers; auxiliary materials are prepared from, by weight, 10-12 parts of corn starch, 8-10 parts of a reactive diluent, 2-4 parts of an antifoaming agent, 15-25parts of a curing agent and 6-8 parts of a toughening agent; the base material is prepared from coal gangue and limestone through mixing. According to the energy-saving and environment-friendly high-strength epoxy resin concrete material, the coal gangue and the river sand are smashed for replacing cement, the production cost is low, energy saving and environment protection are facilitated, the water absorption effect of the limestone is good, the viscosity of the material is increased through the reactive diluent and the corn starch, the antifoaming agent is added, shocking antifoaming is conducted through a vibration machine, the material is even in texture, pores are shrunk, the hardness and the strength of the concrete material are improved through ingredients of the calcium carbonateand microcrystals of the river sand, and the toughness and the resistance of concrete are improved through the asbestos fibers and the toughening agent.

Description

technical field [0001] The invention relates to the technical field of concrete for construction, and more specifically, the invention relates to an energy-saving and environment-friendly high-strength epoxy resin concrete material. Background technique [0002] The research and development of epoxy resin concrete technology first started in the United States. After more than 20 years of development and research in our country, reliable data have been obtained. Because resin concrete does not use cement at all, it is called plastic concrete; it is also called polymer cemented concrete (Pc). It uses different resins and aggregates to make resin concrete with different properties. Generally, in order to reduce the amount of resin, filler silt can also be added. Tests have proved that its crack resistance is twice as high as that of ordinary concrete; two Compared with those, resin concrete has the advantages of fast setting, high strength, chemical corrosion resistance, wear ...
