Abstract
The aim of this paper is to examine the production of artificial aggregate and its potential applications in concrete. The waste materials from industrial are one of the concern issues in sustainable development. Recycle and reuse these waste materials is one of the strategies to produce the better sustainable system. One of the methods is by using the waste materials to produce artificial aggregate by palatalization. There are wide applications of artificial aggregate, for instance construction, agriculture, geotechnical fill, waste water, drainage and many more. Physical properties such as bulk density, specific gravity, unit weight, porosity and water absorption are important criteria. The performance of the artificial aggregate varies, depending on the application.
Highlights
Lightweight concrete has been used as building material for many decades throughout the world, especially in the countries like United States, Japan and Europe
Mehmet gesoylu et al completed a work on Recycling ground granulated blast furnace slag as cold bonded artificial aggregate partially used in self-compacting concrete
At each water-to-binder ratio, the artificial light weight aggregate at replacement level of 0%, 20%, 40%, and 60%. From these journals we have learnt about various materials used for the manufacturing of paver blocks
Summary
Lightweight concrete has been used as building material for many decades throughout the world, especially in the countries like United States, Japan and Europe. The application ranges from lightweight partitions, walls and secondary structural components to the primary structural components. These concrete are either foamed type concrete or no fines, lightweight aggregates concrete. Lightweight aggregate can be produced by nodulizing the fly ash in a pelletizer with a proportionate quantity of water, and further hardened by adopting sintering, cold bonding or autoclaving. When a fine-grained material is moisturized, a thin liquid film develops on the surface of each grain. When the moisturized particles contact each other bridges are formed at points of contact and bonding forces develop gradually when these particles are rotated into balls. Pellets attain strength by mechanical forces, which are produced when the balls bump against each other and against the walls of the pelletizer.
