Problems solved by technology

[0004] The present invention provides a processing method for high-strength environment-friendly concrete, which can effectively solve the phenomenon that the polymer concrete of the composite material proposed in the above-mentioned background technology is easy to cause fractures on the surface of the polymer concrete after use, thus affecting the normal operation of the polymer concrete. At the same time, when the grinding device of this device is in use, the waste PPR powder is placed indoors, which makes the inside of the waste PPR powder sticky, which makes it difficult to grind the waste PPR powder, which increases the difficulty of grinding the waste PPR powder.

Abstract

The invention discloses a processing method for high-strength environment-friendly concrete. The environment-friendly concrete consists of the following components in parts by weight: 100-200 parts ofcement, 40-130 parts of water, 23.8-59 parts of quartz sand, 46.2-82.4 parts of broken stones, 1-2 parts of a water reducer, 10-30 parts of mica powder, 5-30 parts of a waterproof agent, 0.5-2 part of a flame retardant, 40-80 parts of cinerite, 10-30 parts of waste PPR powder, 245-490 parts of sand, 60-120 parts of an adhesive and 60-80 parts of industrial waste slag powder. Waste PPR powder andindustrial waste residue powder, which are added into concrete, are poured into a stirrer to stir, so that use amount of cement is reduced, and production cost is reduced; mica powder, quartz sand andcinerite are added, so that hardness, pressure resistance and water seepage resistance of concrete can be improved; and meanwhile, a heat conduction rate of the concrete is reduced, so that the concrete has highest hardness, highest compressive strength, low heat conduction rate and strong water seepage resistance; and meanwhile, production cost is reduced, waste PPR powder and industrial waste residue powder are recycled, so that the environment-friendly purpose is achieved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a processing method of high-strength environment-friendly concrete. Background technique [0002] Environmentally friendly concrete is a variety of materials used in construction projects. There are many types of environmentally friendly concrete, which can be roughly divided into inorganic materials, which include metal materials and non-metallic materials, and organic materials, which include plant materials, synthetic polymer materials and asphalt. Materials, composite materials, including asphalt concrete, polymer concrete, etc., generally composed of inorganic non-metallic materials and organic materials; [0003] However, the polymer concrete of the existing composite material is easy to cause fractures on the surface of the polymer concrete after use, thereby affecting the normal use of the polymer concrete. At the same time, when the grinding device of th...
