This Foamed glass aggregate is a sustainable replacement construction material for: Foundation details. 26821620 Exfoliated vermiculite, expanded clays, foamed slag and similar expanded mineral materials and mixtures thereof eur-lex.europa.eu 26821620 Geëxpandeerd vermiculiet, geëxpandeerde klei, slakkenschuim en dergelijke geëxpandeerde minerale producten en mengsels daarvan Aggregate is a broad category of particulate materials used in construction including sand, gravel, slag, concrete and foamed glass, to name a few. Lightweight aggregates are either natural such as pumice, diatomite, sawdust, rice husk, volcanic cinders, scoria, etc. Foamed slag aggregate is not available in Australia. GlassCrete (limecrete) floors. Behaviour ofFoamed Slag Concrete at High Temperatures ALIA. Most lightweight aggregate is produced from materials such as clay, shale, or slate. foamed slag concrete. A mix having the density of 1300kg/m3 with a proportion of (1 cement:2 sand), W/C ratio of 0.45, a commercially available additive (SP-1), class F fly ash and a unprocessed blast furnace slag was used. Foamed Slag – was the first lightweight aggregate suitable for reinforced concrete that was produced in large quantity in the UK. UL-FGA is 85% Lighter than quarried aggregate. foam contents of 7.1, 5.3, 4.2, and 2.7% and SP dosages of 0.27, 0.25, 0.24, and 0.15% were used. AKHTARUZZAMAN Civil Engineering Department, Faculty ofEngineering, King Abdulaziz University, Jeddah, Saudi Arabia. In comparison with gravel aggregate concrete, foamed slag concrete had appreciably smaller thermal move- ments for the entire temperature range investigated. "Expanded mineral materials including exfoliated vermiculite, expanded clays, and foamed slag" as a category is defined in this report following the definition given by the United Nations Statistics Division Classification Registry using the Standard International Trade Classification, Revision 3 (SITC, Rev. C. Samples preparation … As mostly no coarse aggregate is used for production of foam concrete the correct term would be called mortar instead of concrete; it may be called "foamed cement" as well. The foam slag should have the following requirement: The heavy impurities should be removed from it. Well established under the trade names of Aglite and Leca (UK), Haydite, Rocklite, Gravelite and Aglite (USA). Sustainable, resilient, and made from 100% recycled glass. or artificial such as foamed slag, sintered fly ash, bloated clay, coke breeze, expanded perlite, etc. By-products of all kinds have become an important source of new raw materials. Roads, sewers, driveways, basements, greenroofs, golf courses, gardens, landscaping, building foundations, etc. In addition, foamed glass aggregate does not absorb moisture and in fact allows any moisture within the sub floor to migrate through it. Concrete, foamed blast furnace slag aggregate Categories: Ceramic; Concrete. 3). The former, however, exhibited progress- ively larger thermal movements than the latter. AeroAggregates®, an ultra-lightweight foamed glass aggregate, is ideal for projects that require fill to be placed over soft compressible soils or over areas with underground utilities. The behaviour of foamed slag concrete was simi- lar to that of sintered pfa concrete. The titled high performance foamed concrete was developed from Portland cement, ultra fine granulated blast-furnace slag, pulverized fly ash and condensed silica fume by means of pre-foaming process. It is used to reduce the weight of the … Alkali activated slag foamed concrete (AASFC) is considered as an environmentally friendly lightweight cementitious material alternatives to similar materials based on Portland cement. Womersleys' supply Foamit a top quality foamed glass lightweight aggregate. The supplementary cementitious materials like fly ash and ground granulated blast furnace slag have been used widely in the manufacture of foam concrete. LD slag has a series of advantages over natural rock in the field of road construction. EN 13242/aggregates for unbound and hydraulically bound mixtures for use in engineering and road construction. such as clay for expanded clay aggregate. The density is normally controlled by substituting fully or part of the fine aggregate with foam. The aggregates have a highly frictional surface and combined with a low unit weight, inertness, high permeability, and insulating properties, foamed glass aggregate is ideal as a lightweight backfill. Foamed slag has been used as a lightweight aggregate for Portland cement concrete.

English-german technical dictionary. The slag aggregate comes from the treatment of slag generated during the steelmaking process in our electric arc furnace steelworks. For other uses, see Concrete (disambiguation). Foam glass is a porous glass foam material.Its advantages as a building material include its light weight, high strength, and thermal and acoustic insulating properties. vi. Slag use … To achieve higher densities for foamed concrete, sand can be employed. Also see, It is established in [4, 5] that in liquid-phase melting processes of reduction and melting of pellets proceed in solid-liquid phase of the, In this case oxidation-reduction processes are combined and proceed in solid-liquid phase of the, Dictionary, Encyclopedia and Thesaurus - The Free Dictionary, the webmaster's page for free fun content, Behavior of phosphorus in liquid-phase reduction melting. The material is crushed and processed into gravel for reuse. Slag has a greater PSV (Polished Stone Value): i.e., greater resistance to wear. foamed slag foamed slag Hüttenbims m, Schaumschlacke f. English-German dictionary of Architecture and Construction. Foam Glass Aggregates reduce the urban waste stream and they are easy to produce at any location. Granulated blast furnace slag has been used as a raw material for cement production and as an aggregate and insulating material. Where is AeroAggregate manufactured? To produce lightweight aggregate, the raw material (excluding pumice) is expanded to about twice the original volume of … foamed slag expanded blast-furnace slag, foamed blast-furnace slag The lightweight cellular material obtained by controlled processing of molten blast-furnace slag with water, or with water and other agents such as steam or compressed air or both. What is aggregate? At a time of material shortages, it had the advantages of being cheap, quick and permanent. The invention provides a foamed asphalt-steel slag mixture which comprises the following components in percentage by weight: 20% of foamed asphalt, 70-73% of steel slag aggregates, 1-2% of a sodium silicate solution, 1-3% of cement powder, and 5% of water. up to 85% lighter than traditional aggregates. Due to its positive technical characteristics, LD slag is used all over the world in road and railway construction and for engineering. Construction aggregate, or simply aggregate, is a broad category of coarse- to medium-grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates.Aggregates are the most mined materials in the world. 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]. , shale, or slate ( UL-FGA ) is made from 100 % recycled container glass trade.
