1. Introduction
Industry development, population growth and the rising of consumerism have produced a rapid increase in the production of waste materials. It would be desirable to reduce waste disposal and promote recycling of waste as raw materials for other productions whenever it is possible. A large part of solid waste is produced by iron and steel industries so, if they are not properly disposed, they might damage environment and consequently have influence on human health. Steel scale waste (SSW), a by-product of steel production, is formed on the surface of steel monoliths during their high temperature thermal treatments after casting; SSW mainly contains iron oxides and a minor fractions of other oxides as function of steel composition. This type of waste, generally known as “calamine”, is presently mainly disposed of to landfill or used to prepare counterweights concretes, due to the higher specific gravity of calamine with respect to that of all the other components that are generally used to prepare ordinary mortars or concretes. The use of many industrial waste in concretes and/or mortars production could by-pass the problem of their landfill disposal and, at the same time, promote the production of sustainable building materials (Chowdhury et al., 2014). Alwaeli and Nadziakiewicz (2012) proposed scale and steel chips waste as a partial replacement of sand in concrete while Takeda et al. (2009) studied the physical properties of iron-oxide scales. In the present research, mortars were produced using a fixed ratio of cement/aggregate (c/a = 1/3), as it has been often proposed in literature by other authors (Pèra et al., 1999; Qasrawi et al., 2009), whereas SSW was previously milled and transformed into a powdered product and then added in different proportions to replace part or at least all of the fine fraction of the natural aggregate.
