Recycled and Carbon Neutral Fly-ash Aggregates as a Construction Material

Abstract

Since certain countries that rely on coal for the running of their power plants are creating an increasing volume of fly-ash, it is vital to discover new utilization areas. Utilizing Extensive Applications is one of these domains. One example is the production of specialized shape aggregate (METAL) for use in different geotechnical applications and highway construction. This benefits the efficient use of a mineral resource and the solution to the fly ash disposal problem. To achieve these goals, fly-ash was pressed into a specially designed mould to produce lightweight aggregate in the shape of a METAL. The mould was used to manufacture METAL fly-ash aggregates, which were then given a set amount of time to cure [1]. The physical as well as mechanical parameters of the METAL fly-ash aggregates are next examined. It compared the test outcomes for natural and fly-ash aggregate. For the purpose of evaluating the workability of the METAL aggregate, concrete cubes were constructed. Finally, a cost study comparison between fly-ash aggregate and natural aggregate was finished. When silica fume, as well as blast furnace slag, as well as blast furnace slag, were included in the mixture, the metal aggregate functioned effectively. Every building project can substitute METAL aggregate for natural aggregate.
