Abstract

The invention relates to the technical field of high-strength concrete, and particularly discloses C60 high-strength resin concrete as well as a preparation process and application thereof. The C60 high-strength resin concrete is mainly prepared from the following raw materials in parts by weight: 1000 to 1200 parts of stones, 750 to 850 parts of sand, 280 to 320 parts of cement, 40 to 60 parts of slag powder, 80 to 100 parts of fly ash, 5 to 10 parts of fibers, 6 to 9 parts of a water reducing agent, 160 to 175 parts of water, 80 to 100 parts of epoxy resin and 5 to 15 parts of a curing agent. The curing agent is at least one of chitosan quaternary ammonium salt and diethylaminoethyl cellulose. The C60 high-strength resin concrete can be used for roads, bridges, water conservancy projects and the like, and has the advantages of high strength and cracking resistance.

Description

technical field [0001] This application relates to the technical field of high-strength concrete, more specifically, it relates to a C60 high-strength resin concrete and its preparation process and application. Background technique [0002] Concrete is a building material made by mixing cementitious materials, fine aggregates, stones, water reducers, water and other raw materials. It can withstand large loads and is widely used in roads, bridges, and building construction. With the continuous development of the construction industry, ordinary concrete has low tensile tension, high brittleness, and is easy to crack. In order to overcome the above shortcomings, technicians mix ordinary concrete and polymers in a certain proportion to make polymer-modified concrete to improve the concrete. properties such as strength and toughness. [0003] There are various types of polymers added to polymer-modified concrete, among which epoxy resin, as a binder, has high elasticity and stre...
