Abstract

The invention belongs to the field of concrete ground hardening agents, and particularly discloses a dry-scattering ground hardening agent and an using method thereof. The dry-scattering ground hardening agent is prepared by uniformly mixing the following raw materials in parts by weight: 320 to 350 parts of cement, 15 to 20 parts of silica fume, 750 to 800 parts of copper slag and 4 to 6 parts ofa water reducing agent. The dry-scattering ground hardening agent is prepared by taking copper slag undergoing treatment and grading optimization as aggregate, so that the wear resistance, surface strength, impact resistance and oil resistance of the ground are improved greatly. Meanwhile, the problem of high aggregate cost in the conventional alloy aggregate and metal aggregate dry-scattering ground hardening agents is solved, and a novel way is provided for the efficient recycling utilization of the copper slag.

Description

technical field [0001] The invention belongs to the field of concrete floor hardeners, and specifically discloses a dry-sprinkle type ground hardener and a using method thereof. Background technique [0002] The ground hardener can effectively overcome the shortcomings of concrete or cement mortar ground, such as easy sanding, peeling, low hardness, and poor wear resistance, and can greatly improve the ground wear resistance, surface strength, impact resistance and oil resistance. According to the presence or absence of aggregates and different types of aggregates, ground hardeners can be divided into four categories: liquid hardeners, non-metallic aggregates, alloy aggregates, and metal aggregates. Among them, non-metallic aggregates, alloy aggregates, and metal aggregates can all be classified as dry-shattering ground hardeners, and their aggregates are generally washed river sand, quartz sand, corundum, alloy particles, metal particles, etc. In terms of wear resistance a...
