2017-8-5 aggregate for concrete is ASTM C 33. 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

A direct alternative to primary aggregates, slag aggregates offer versatility and most importantly sustainable solutions to standard construction products. Steel aggregates have a high abrasion and crushing resistance for road applications: air cooled blast furnace products bond particularly well to cement and bitumous binders.

The production method of geopolymer lightweight aggregates (GLAs) is explored in this study through crushing technique, which has a good prospect for massive industrial production. Geopolymer cubes with the dimension of 100 mm × 100 mm × 100 mm were firstly produced using one-part geopolymer technology and then crushed into coarse aggregates ...

2015-9-10 Most lightweight aggregate is produced from materials such as clay, shale, or slate. Blast furnace slag, natural pumice, vermiculite, and perlite can be used as substitutes, however. To produce lightweight aggregate, the raw material (excluding pumice) is expanded to about twice the original volume of the raw material.

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. ...

2021-11-16 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 quenching blast furnance slag. The quenching of slag can be done by the following two methods: (a) Water jet process.
