PRM concrete reinforcing agent

Abstract

The invention relates to the technical field of comprehensive utilization of red mud, gypsum and fly ash, in particular to a PRM concrete reinforcing agent. The PRM concrete reinforcing agent is prepared from red mud, gypsum, fly ash and mineral powder, wherein the weight percentages of the raw materials are as follows: 5%-30% of the red mud, 5%-30% of the gypsum, 10%-50% of the fly ash and 10%-50% of the mineral powder. The preparation method comprises the following steps: respectively filtering out particles with the diameter of 0.5 or more cm from the red mud, the gypsum, the fly ash and the mineral powder, drying, and sufficiently and uniformly mixing. The PRM concrete reinforcing agent has the advantages of high strength and low price, utilizes a large amount of solid wastes such as red mud produced by alumina enterprises, desulfurized gypsum produced by thermal power plants, white gypsum produced by titanium dioxide enterprises, red gypsum and the like, changes wastes into valuables through comprehensive utilization, and solves the problem of environment-friendly solid waste treatment in the industries.

Description

technical field [0001] The invention relates to the technical field of comprehensive utilization of red mud, gypsum and fly ash, in particular to a PRM concrete reinforcing agent. Background technique [0002] Concrete refers to the artificial stone made of cement as the main cementitious material, mixed with water, sand, stones, chemical admixtures and mineral admixtures when necessary, mixed in appropriate proportions, uniformly stirred, compacted and cured. Concrete is mainly divided into two stages and states: the plastic state before setting and hardening, that is, fresh concrete or concrete mixture; the hard state after hardening, that is, hardened concrete or concrete. The strength grade of concrete is divided by the standard value of cubic compressive strength. The strength grade of ordinary concrete in China is divided into 14 grades: C15, C20, C25, C30, C35, C40, C45, C50, C55, C60, C65, C70, C75 and C80 .

Problems solved by technology

[0003] The use of traditional technology to produce concrete requires a large amount of cement and high cost. As the country's environmental protection control becomes more and more stringent, cement manufacturers are constantly reducing and controlling production capacity, which makes the cost and price of cement use more and more Correspondingly, the production cost of concrete is also getting higher and higher, this problem needs to be solved urgently
