Feb 09, 2016 Blast furnace slag is the most commonly used artificial aggregate or lightweight aggregate. Evaluating Quality of Aggregates Selecting an aggregate material for use in an asphalt concrete depends upon the availability, cost, and quality of the material, as well as the type of construction that is intended.If local binding material such as lime slag, lime cinder, etc. is available, the same can also be adopted as the binding material. Aggregates For lightweight concrete, the loose porous materials are used as the aggregates. The natural porous aggregates can be obtained by crushing lightweight rocks.
Apr 24, 2012 Figure 2 shows the photographic view of four reference LWAs the pelletization, namely ﬂy ash A (FA), ﬂy ash B (FB), blast furnace slag (G) and, a mixture of ﬂy ash A without cement. 2.3 Test on lightweight aggregate grains The properties of lightweight aggregates were tested for speciﬁc gravity, water absorption, and crushing strength.Pelletized or expanded slag results when molten slag is quickly cooled using water or steam. It produces a lightweight aggregate that can be used for concrete masonry, lightweight fill, or can be ground into a cementitious product. For rmation on slag aggregates, visit the National Slag.
Crushing strength of lightweight aggregates depends on the efficiency of production, type of binder used and size of the aggregate formed. Fly ash based slag pellets were produced in the present.Synthetic aggregates may be either byproducts of an industrial process, in the case of blast furnace slag, or products of processes developed to manufacture aggregates with special properties, as in the case of expanded clay, shale, or slate used for lightweight aggregates. Some lightweight aggregates such as pumice or scoria also occur naturally.
Jul 23, 2014 Lightweight Aggregate Pumice stone. It is also a suitable material to produce light weight concrete provided it is free from volcanic dust or clay etc. It gives concrete having density 800 to 1100 kg cm 3 and has a high thermal insulation. Its strength is about 15 to 40 kg cm 2. Foamed slag. Foamed slag is also used for preparing light weight.• ‘Aggregate’ is a term for any particulate material. It includes gravel, crushed stone, sand, slag, recycled concrete and geosynthetic aggregates. Aggregate may be natural, manufactured or recycled. • Aggregates make up some 60 80 of the concrete mix. They.

Aggregates of expanded shale, clay, slate, and slag (Fig. 5 3) are used to produce struc tural lightweight concrete with a freshly mixed density.
The high slag crushing index of coarse aggregate can result in a limit slag content (20 ), and the concrete strength can decrease with increasing slag rate. The lowest concrete strength of less than 30 Mpa appears when the fly ash replacement rate is 40 and the slag replacement rate is 40 .Apr 10, 2013 Expanded slag – Expanded slag use is largely for lightweight concrete aggregate, much of it in concrete block and other precast units. The majority of the expanded slag is used in concrete, where it provides better thermal insulation and fire resistance properties than obtainable with comparable concretes made with other aggregates.
Nickel Slag Air cooled nickel slag is brownish black in color. It crushes to angular particles but has a smooth, glassy texture. The specific gravity of air cooled nickel slag may be as high as 3.5 (15), while the absorption is quite low (0.37 percent). (3) The unit weight of nickel slag is somewhat higher than that of conventional aggregate.National Slag Association. Since 1918, The NSA has promoted the use of Blast Furnace and Steel Furnace Slag. Blast Furnace slag has been called the All Purpose Aggregate as it can be used in all construction applications as either a normal weight or lightweight (expanded or pelletized) aggregate depending on how it was formed and processed.
Jun 01, 2019 Reuse of harbor sediment and BOF slag as lightweight aggregates is feasible. • Sintering at 1175 C for 15 min after preheating at 500 C for 10 min is optimal. • BOF slag addition is recommended not exceeding 30 in weight. • The LWA product shows low water soluble chloride and heavy metals leachability.The effects of cement fly ash ratios on the volcanic slag Aug 01, 2008 In addition, no fines aggregate and FALC were compared with CLC and the effect of FA on the strength and unit units is the lightweight concrete block.
Granulated blast furnace slag, n —the glassy, granular mate rial formed when molten blast furnace slag is rapidly chilled, as by immersion in water. gravel, n —coarse aggregate resulting from natural disintegra tion and abrasion of rock or processing of weakly bound conglomerate. grout, n —a cementitious mixture, with or without admixtures, that is used primarily to fill voids. grout.Vi. Expanded or Foamed Slag Expanded slag is one of the most important types of light weight aggregates. The blast furnance slag is a by product of the manufacture of pig iron. The expanded or foamed slag is produced by rapidly quen ching blast furnance slag. The quenching of slag can be done by the following two methods (a) Water jet process.
Further, as these slag crushers are also lightweight, these are easy to transport and handle. These also do not require any expensive foundation support as required in other crushers. The different technical specifications these are made available in is on parameters of diameters, crushing capacity, input size, output size and others.Mar 15, 2021 Crushers break down large rocks into smaller pieces to such as sand, gravel, or slag to be used in aggregate via pressure or striking. Typically, rocks will go through multiple rounds of crushing to reach the desired size. Crushers are also used in.
Aug 11, 2018 The use of slag aggregates from iron and steel production in construction dates back to the Romans who used crushed slag from the crude iron production of that time to build their roads. Nowadays, slag is still used to build roads. However, slag use is not limited to roads any , but slag aggregates are widely used in all kinds of civil works.The present Investigation has been undertaken to study the effect of blast furnace slag and crusher dust on the mechanical properties of concrete, when coarse aggregates is replaced by blast furnace slag and crusher dust is replaced with fine aggregate in different percentages i.e. 0 , 10 , 20 , 30 , 40 , 50 , 60 , 70 , 80 , 90 and .
Blast furnace slag is a secondary aggregate used widely in construction because of its performance attributes and durability.
