Effect of batched water exposed to a constant magnetic field on the properties of concrete filled with waste fly ash, phosphogypsum and starch

Abstract

The influence of batched water exposed to a constant magnetic field (B = 1 T) on the properties of concrete was investigated. Fillers such as coal fly ash (CFA), phosphogypsum (PB) and native potato starch dispersed in epoxy resin [EP(S)], were used to obtain concrete based on Portland cement (PC). The magnetized batched water had a positive effect on the properties of concrete, reducing water absorption and increasing flexural and compressive strengths. The obtained concrete is a new promising building material that can be used to manufacture e.g. building foundations, flush-mounted installations and insulation layers.
