Embodiment 1

[0023] A kind of large-volume epoxy resin concrete pouring technique of the present invention comprises the following steps:

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

[0025] (2) Heating the epoxy resin to 40°C, adding the curing agent ethylenediamine and the diluent xylene, and mechanically mixing to obtain a gelled material;

[0026] (3) Add the dried sand, stone and cement into the cementitious material, and continue mechanical mixing evenly;

[0027] (4) Build a formwork support of the required size, layer the fabric along the length direction, and the thickness of each layer of fabric is 20mm. After the fabric is completed, use an attached vibrator to vibrate until the air bubbles are completely discharged to the concrete surface. Air bubbles are removed, and the next layer of pouring must be carried out before the previous layer of epoxy resin concrete is hardened, a...

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...
