Artificial aggregates are produced by allowing powder materials to agglomerate to form ball-like rounded pellets by sprinkling the optimum quantum of liquid in the pelletizer. …
Production of different artificial aggregates from various sources involves various methods. The primary focus is integration of the reduced residue to any definite predetermined size for their targeted production. After the process of agglomeration through pelletisation, the new post-processed pellets ...
The excessive use of natural aggregates raises mining activity. Further, it leads to environmental damage, which can be reduced using artificial aggregates produced from waste powdered materials. This study discussed the production process of alkali-activated artificial coarse aggregates and how their use affects the behavior of concrete. The different concrete …
The production of lightweight aggregate based on waste is an important step towards sustainable and ecological construction. It contributes to reducing the negative impact of the construction sector on the environment by reducing the consumption of natural raw materials and reducing waste of various origins, including rubble concrete. The physical and mechanical …

Compared to natural aggregates, artificial aggregates prepared by solid waste can reduce the environmental impact of the construction industry, reduce production costs, and improve the quality of ...
This experimental cum research exploration is focused on the production of artificial aggregates with an adoption of pelletization technique. The influential factors for ascertaining the efficiency of the production process are nature of binding agent, required moisture content, process duration and dosage of alkali binder.
Therefore, this article proposes a method of obtaining artificial lightweight aggregate consolidated using two methods: drum and dynamic granulation. Hardening was …
Cleaner production of artificial stone aggregates from industrial waste is an alternative to natural stone aggregates. Although earlier studies have reported the use of artificial aggregates, a ...
The widespread use of natural aggregates is one of the main causes of the depletion of natural resources, as aggregates are constituents of several construction materials. Alternatively, it is, today, proven to be feasible to use mining tailings, either natural or recycled materials, to produce artificial aggregates through specific processes. A possible way to …
Artificial aggregates are made up of waste materials, such as fly ash, husks, or volcanic form and ground granulated blast-furnace slag (GGBS) [21] Various types of lightweight aggregate have been ...
Crushing: The crushing method of hardened alkali-activated pastes is the most suitable for the large-scale production of artificial aggregates in practical manufacturing. In a recent study (Xu et al., 2021b), the crushing procedure for producing CB-AAA was reported in detail. It is good to mention that crushing is also the common method for ...
Accelerated carbonation is envisaged to be a significant curing method for the development of cement-free artificial aggregates. In this paper, two accelerated carbonation approaches, applied during granulation and post-curing respectively, are investigated for their influences on the properties of the aggregates made by 100 % basic oxygen furnace slag …
