Background

Concrete, referred to as "concrete" for short: refers to the general name of engineering composite materials formed by cementing aggregate into a whole by cementing materials. The term concrete generally refers to cement as the cementing material and sand and stone as the aggregate; the cement concrete, also called as common concrete, is obtained by mixing with water (which may contain additives and admixtures) according to a certain proportion and stirring, and is widely applied to civil engineering.

The iron sand is added in the concrete stirring process, so that the binding force between the aggregate and the cement paste can be enhanced, the compressive strength of the concrete is improved, and the wear resistance is improved; therefore, a proper amount of iron sand can be added into the existing part of concrete with special purposes in the stirring process; however, the concrete raw material can be doped with partial magnetic ores, and the magnetic ores can attract small iron sand particles in the concrete stirring process, so that the iron sand is gathered at a certain part, the distribution of the iron sand in the concrete is uneven, and the strength of the concrete is reduced.
