Abstract
Improved concrete or mortar materials wherein cement in the precursors for these is replaced by electric arc furnace dust in amounts from 0+% to 4% or more based on the amount of cement by weight. In addition, the electric arc furnace dust can be used as an additive to obtain the same effect.
Claims8
In a method for modifying properties when casting cement based concrete or any mortar, the improvement comprising:
- replacing from about 1% to about 4% by weight of cement in a concrete or mortar precursor mixture with electric arc furnace dust, formulating a cement, electric arc furnace dust, and an aggregate mixture with water to obtain a concrete or mortar precursor mixture, and casting said mixture to obtain concrete or mortar with improved set retardation, and enhanced properties.
In a method for disposal of electric arc furnace dust, the improvement comprising replacing up to 4% by weight of cement in a concrete or mortar precursor mixture with electric arc furnace dust and casting said precursor mixture to obtain commercially useful concrete or mortar with improved properties.
