  Bloating mechanism in lightweight aggregates: Effect of processing ...

  20201120 · The bloating mechanism can be investigated by either ex-situ or in-situ approaches: the former consists in the production of lightweight aggregates in a furnace and testing properties after firing [17], [24], [34]; the latter observes the aggregate behaviour during firing by hot-stage microscopy or thermal analysis [38], [39].

  Production of Lightweight Aggregates by Means of Cold …

  In this context, the final goal of this study is the production of lightweight artificial aggregates through the recycling of industrial solid waste, such as fly ash, blast furnace slag, and marble sludge. The results show that the aggregates produced can be classified as lightweight aggregates and are suitable for road paving.

  Environmental Impact and Sustainability of …

  201241 · Abstract. The present work presents a means of evaluating the particle size distribution of aggregates on hardened concretes via an image processing based technique. Such a technique may be employed to the reconstitution of hardened concrete composition, which is a matter of interest concerning, specially, lightweight aggregate concretes.
