Abstract

The invention discloses non-sparking wear-resisting concrete and a method for carrying out floor construction through the concrete. The non-sparking wear-resisting concrete is prepared from, by weight, 3.42-4.45 parts of conductive powder, 0.5-2.5 parts of common sand, 3.2-4.88 parts of coarse aggregate, 2-2.2 parts of SBS high polymer modified emulsified asphalt, 0.5-1.2 parts of cement, 1 part of water and 0.4-0.8 part of an additive. The additive is a combination of one or more of a fire retardant, a wear resisting agent, a foaming agent, a carbon forming agent, a carbon catalyst, a water reducing agent and a pumping agent. The conductive powder is a combination of one or more of spherical silicon-based conductive powder, electric mica powder, conductive titanium dioxide and conductive barium sulfate. The non-sparking wear-resisting concrete can be widely applied to ground construction of combustible product warehouses, production areas with sparks prone to being generated or explosive plants, hangars and other areas with high requirements for the fireproof degree and wear resisting degree.

Description

technical field [0001] The invention belongs to the technical field of building concrete, and in particular relates to non-fire wear-resistant concrete and a floor construction method using the concrete. Background technique [0002] With the development of technology, the function of concrete is gradually refined. In industrial buildings, such as military manufacturing, liquefied petroleum gas stations, gas production plants, oil storage, oil station docks and other flammable and explosive projects, warehouses and other areas, There are special requirements for fire and explosion protection on the ground or walls. In addition, with the acceleration of my country's industrialization process, large-scale industrial plants have sprung up, and the high-tech trend of industrial plants is becoming more and more obvious. The requirements for the use of the ground are also getting higher and higher, and sometimes it is necessary to meet two or more functions. need. Due to the flam...
