Example Embodiment

[0022] Example 1

[0023] A large volume epoxy resin concrete pouring process of the present invention includes the following steps:

[0024] (1) Weigh 180kg of epoxy resin, 15kg of curing agent ethylenediamine, 5kg of diluent xylene, 500kg of dried sand and stone, and 180kg of cement by weight;

[0025] (2) Heat the epoxy resin to 40°C, add the curing agent ethylene diamine and the diluent xylene, and mix them evenly to obtain a gelling material;

[0026] (3) Add the dried sand, stone and cement to the cementitious materials, and continue to mix them evenly;

[0027] (4) Build the template support of the required size, layer the cloth along the length direction, the thickness of each layer is 20mm, after the cloth is finished, vibrate with an attached vibrator until the air bubbles are completely discharged to the concrete surface, and the concrete surface is manually To remove air bubbles, the next layer must be poured before the upper layer of epoxy concrete is hardened, layer by la...

Abstract

The invention discloses a large-volume epoxy resin concrete pouring process which takes epoxy resin, a curing agent ethylenediamine and a diluent xylene as cementing materials, after machine-made sandand stone are dried, the machine-made sand and the stone are uniformly stirred through mechanical stirring, and layered casting and mechanical adhesion type vibration are adopted, so that internalbubbles generated by the curing agent are fully removed. The invention provides the large-volume epoxy resin concrete pouring process, the internal gas bubbles of the concrete can be fully removed, and the large-volume pouring is realized, meanwhile the strength of the concrete can be effectively guaranteed, the advantages of high strength and weak supplement of the epoxy resin are maintained, andthe cost of later-period manual repair is reduced.

Description

technical field [0001] The invention relates to a concrete pouring process, in particular to a large-volume epoxy resin concrete pouring process. Background technique [0002] Epoxy resin concrete is made of epoxy resin as the main material, mixed with an appropriate amount of curing agent, plasticizer, diluent and filler as adhesive, and sand and stone as aggregate, which are mixed, formed and cured. Composite material is a kind of pure polymer concrete in polymer concrete. [0003] It has high strength, good toughness, high impact strength, good chemical corrosion resistance, wear resistance, water resistance and frost resistance, and has high bonding strength with metal and non-metal materials, and good electrical insulation, which makes up for the tensile strength of cement concrete. Low, small tensile strain, low crack resistance, high brittleness and other shortcomings. The cured epoxy resin concrete has strong resistance to atmosphere, moisture, chemical medium, bac...
