Phosphorus slag based environmentally-friendly building material and preparation method thereof

Abstract

The invention discloses a phosphorus slag based environmentally-friendly building material and a preparation method thereof. The phosphorus slag based environmentally-friendly building material comprises the following components in parts by mass: 14.61 to 44.08 parts of phosphorus slag powder, 1.11 to 18.72 parts of building waste residue powder, 1.11 to 6.24 parts of sialic sphere powder, 1.11 to3.12 parts of nanometer silex, 2.10 to 8.46 parts of an alkaline activator, 20.81 to 66.51 parts of sand, 11.08 to 16.53 parts of water and 0.22 to 1.17 parts of an efficient polycarboxylate superplasticizer. The phosphorus slag based environmentally-friendly building material is low in cost, simple in preparation technology and short in maintenance time.

Description

technical field

[0001] The invention relates to the technical field of building materials, in particular to a phosphorus slag-based environment-friendly building material, and also relates to a preparation method of the phosphorus-slag-based environment-friendly building material. Background technique

[0002] With the rapid development of my country's economy, there are more and more construction and industrial solid wastes. my country produces immeasurable old city renovation waste concrete, nearly 10 million tons of waste glass, and more than 95 million tons of phosphorus slag every year, and the trend is increasing year by year. Most solid wastes are stacked in the open air or landfilled, occupying a large amount of land and polluting the environment. A large amount of solid waste cannot be fully utilized again, wasting social resources. Finding an effective and green construction and industrial solid waste disposal method has become an urgent need of the current socie...
