Abstract

The invention belongs to the field of steel bridge deck pavement, and particularly relates to graphene-doped resin concrete, a preparation method thereof and a pulse electromagnetic wave rapid curingmethod. The technical key points are as follows: the graphene-doped resin concrete is prepared from a main agent A, a curing agent B, suspended compact graded aggregate C and graphene powder, whereinthe main agent A comprises the following components in parts by weight: 50-80 parts of epoxy resin; 10-30 parts of an epoxy-terminated carbamic acid ester prepolymer; 5-15 parts of an epoxy-terminateddiluent and 1-3 parts of a coupling agent; and the graphene-doped resin concrete is used for paving a steel bridge deck. The graphene powder is doped in the resin concrete, and a three-dimensional heat conduction net is constructed in the resin concrete by utilizing the graphene powder, so that the heat conduction coefficient of the resin concrete is further improved, and the curing speed of theresin concrete under the action of pulse electromagnetic waves is greatly increased.

Description

technical field [0001] The invention relates to the field of steel bridge deck pavement, in particular to a graphene-doped resin concrete, a preparation method thereof, and a pulse electromagnetic wave rapid maintenance method. Background technique [0002] Epoxy concrete has the advantages of high strength, high cohesion, corrosion resistance, etc., and is widely used in steel bridge deck pavement projects at home and abroad. Epoxy concrete needs to be mixed at 120~180°C. Although the residual heat of mixing can promote its curing to a certain extent, it still needs to be cured at room temperature for a long time to achieve the final strength. Long-term road closure and maintenance have had a great impact on transportation, local economic development, and national travel satisfaction. [0003] In recent years, many scholars at home and abroad have made a series of attempts on how to shorten the curing time of epoxy concrete and shorten the time of road closure. However, t...
