Abstract

The invention discloses a resin concrete, which comprises, by weight, 0.8-1.2 parts of an epoxy resin, 0.2-0.45 part of a curing agent, 3.5-4.0 parts of stone, and 3.5-4.0 parts of fine sand. According to the present invention, the resin concrete has advantages of high efficiency, good repair effect, excellent physical mechanical property, excellent tensile resistance, excellent compression resistance, excellent impact resistance, simple construction and short construction operation time, wherein the traffic can be opened after 3 h.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a modified resin concrete and an application method thereof. Background technique [0002] In the form of increasing traffic volume on expressways, the operating pressure on roads and bridges continues to increase, and when repairs are required, the closure of roads has a greater impact. [0003] The structural characteristics of epoxy resin endow it with excellent product performance. As an adhesive, it has excellent bonding performance to various metals, non-metals, thermoplastics, and thermosetting plastics, and has high bonding strength, especially suitable for structural bonding. , The structure synthesized by sand and stone materials also has excellent physical and mechanical properties, and has excellent tensile, compressive and impact resistance properties. These advantages apply to building structures in harsh environments. [0004] When existing epoxy resins...
