It is ideal for sub floors and for preventing cold bridging in well insulated new builds, can play an important role by insulating old buildings whilst retaining breathability and … Infrastructure construction projects including lightweight embankments, load distribution platforms and insulating subgrade, as well as lateral load reduction behind retaining walls and structures. However, due to the lack of understanding of important properties, the use of this type of materials is still very limited. Lightweight beams (50 x 75 x 850mm) using foamed slag aggregate, were tested in flexure at steady state temperatures up to 600°C. aggregate applications; granulated, which is specifically produced in a vitrified state for slag cement manufacture; and expanded (or foamed as it is known in Europe), which is used mainly as lightweight aggregate in structural and masonry concrete.1 A relatively new process, initially developed by National Slag Limited in Hamilton (Ontario) as a Slag has a greater PSV (Polished Stone Value): i.e., greater resistance to wear. Based on the classification of lightweight concrete according to the level of compressive strength and aggregate type by Mindess and Young [4], lightweight aggregate concrete using artificial lightweight aggregate (ALWA) or lightweight coarse sintered fly ash and foamed slag aggregates can produce compressive strength values of 17-41 MPa with a density range of 1500-2000 kg/[m.sup.3] [4]. Behaviour ofFoamed Slag Concrete at High Temperatures ALIA. The density is normally controlled by substituting fully or part of the fine aggregate with foam. The most common use is as an aggregate in the manufacture of asphalt. Large embankments can be built with low net surcharge due to the low unit weight and high friction angle of ultra-lightweight foamed glass aggregate.

The foam concrete name itself define the character of the concrete that being light weight concrete made out of a foaming agent which doesn’t have coarse aggregate in it as a mixture, and could also termed as aerated mortar since it having air voids in it. AeroAggregate is a foamed-glass aggregate made from 100% recycled container glass. At a time of material shortages, it had the advantages of being cheap, quick and permanent. View chapter Purchase book ... Other Materials and Aggregates for Foam Concrete. 3). It is ideal for sub floors and for preventing cold bridging in well insulated new builds, can play an important role by insulating old buildings whilst retaining breathability and … Infrastructure construction projects including lightweight embankments, load distribution platforms and insulating subgrade, as well as lateral load reduction behind retaining walls and structures. However, due to the lack of understanding of important properties, the use of this type of materials is still very limited. Lightweight beams (50 x 75 x 850mm) using foamed slag aggregate, were tested in flexure at steady state temperatures up to 600°C. aggregate applications; granulated, which is specifically produced in a vitrified state for slag cement manufacture; and expanded (or foamed as it is known in Europe), which is used mainly as lightweight aggregate in structural and masonry concrete.1 A relatively new process, initially developed by National Slag Limited in Hamilton (Ontario) as a Slag has a greater PSV (Polished Stone Value): i.e., greater resistance to wear. Based on the classification of lightweight concrete according to the level of compressive strength and aggregate type by Mindess and Young [4], lightweight aggregate concrete using artificial lightweight aggregate (ALWA) or lightweight coarse sintered fly ash and foamed slag aggregates can produce compressive strength values of 17-41 MPa with a density range of 1500-2000 kg/[m.sup.3] [4]. Behaviour ofFoamed Slag Concrete at High Temperatures ALIA. The density is normally controlled by substituting fully or part of the fine aggregate with foam. The most common use is as an aggregate in the manufacture of asphalt. Large embankments can be built with low net surcharge due to the low unit weight and high friction angle of ultra-lightweight foamed glass aggregate.
