  Mechanical properties and microstructure of slag and fly ash …

  202241 · Mechanical performance studies on miscanthus lightweight concrete have been carried out using natural hydraulic lime and Portland cement binders [8], [9]. Alkali-activated industrial waste materials (AAIWMs), such as slag and fly ash precursors, constitute an interesting alternative to cement and lime for strength improvement.

  Assessment of Properties of Structural Lightweight Concrete …

  2023626 · The main aim of the paper was to assess whether the lightweight concrete with a new type of sintered fly ash aggregate can be used as a structural material for post-tensioned elements subject to high effort. This purpose was achieved by comparison of the properties of lightweight aggregate concrete with Certyd aggregate (LWAC) and normal …

  Structural concrete using sintered flyash lightweight aggregate…

  20171115 · Sintered flyash lightweight aggregates (LWA) can be used for various structural and non-structural applications. The commercial production of artificial lightweight aggregates from flyash through sintering has started in1960s [6]. Aardelite, Lytag, Pollytag, Fa-Light are some of the commercially available flyash LWAs around the world.

  2013112 · The production of artificial fly ash lightweight aggregate is effectively carried out by two techniques namely granulation and compaction. The processing of agglomeration theory was developed in 1940’s [2]; Granulation technique involves in the formation of solid pellets by addition of moisture and further with the application of rotating force.
