Non-structural Performance of Pastes and Mortars Fabricated from Alkali Activated Electric Arc Furnace Slag
Journal Title: Current Trends in Civil & Structural Engineering (CTCSE) - Year 2019, Vol 2, Issue 5
Abstract
With the implementation of legislation on waste management in the European Union, which sets objectives in terms of promoting the re-use and recycling of products, the industry and the academic community have been making additional efforts in order to develop solutions that aim to use industrial by-products as raw materials, more specifically, in the study of alternative binders to Portland cement. In this work, an extensive experimental campaign is carried out to characterise, from the non-structural point of view, a set of alkali activated mixtures fabricated with electric arc furnace slag (EAFS) and phosphate sludge (PS) as the precursor, and two different activators (a commercial solution composed by sodium hydroxide and sodium silicate, and a solution used to clean the sand moulds from the aluminium processing industry). Results reveal that the mixtures based on EAFS present some handicaps in terms of shrinkage and workability, and that these properties are influenced by the nature of the activator and the presence of the PS.
