· The purpose of this study was to improve the recycling rate of industrial wastes by investigating the bloating mechanism of artificial lightweight aggregate depending on the ramping rate and time, which is a dynamic parameter in the production of artificial lightweight aggregate. In this study, coal bottom ash and dredged soil at a weight ratio of 1 : 1 from a …
· Further, new types of artificial lightweight aggregate with superior water absorption properties have been developed 5, 6. These lightweight aggregates have created considerable interest in recent years, because their application improves the workability, strength, and resistance to freezing and thawing of lightweight aggregate concrete. ...
The thrust for sustainability has resulted in new types of FA, such as biomass FA. Moreno-Maroto et al. [30] have shown the formation of lightweight artificial aggregate using biomass FA by the process of sintering, providing solutions for its utilization. Meanwhile other works toward sustainability include showing the industrial application of ...
The artificial lightweight aggregate using alkali-activated fly ash and silica fume has a high water absorption value, which does not meet the limits recommended by ACI-213R (less than 25%) . The water absorption value of LWAs, using alkali-activated fly ash and GBFS, ranges from 18.73% to 30.09% . The LWAs ...
· Artificial lightweight aggregate manufacturing technology using waste provides valuable economic and environmental benefits. The Republic of Korea uses 200 million tons of aggregates annually, making this country a very large market. The manufacture of lightweight aggregates using waste can enter very large amounts of other types of waste into ...

· Lightweight aggregates. Our lightweight aggregates from Lytag® are made from fly ash generated by coal fired power stations. Our technology heats the fly ash to 1,100°C to create a hard pellet, with a honeycombed internal structure. Which can then be used as a superior, lightweight aggregate which is up to 50% lighter than natural aggregate.
Production of artificial aggregate from sintered ash is possible mainly because of the fly ashes. [2] Focus of this paper is to compare various types of ashes for lightweight aggregate produced with cold-bonding. Apart from the fly ashes and FBC ashes are also tested bottom ashes from FBC technology. From the results could be assumed, that ...
Global artificial lightweight aggregate includes Arcosa, Leca (Saint-Gobain), etc. Global top 3 companies hold a share about 20%. North America is the largest market, with a share about 40%, followed by Europe and China with the share about 30% and 10%.

Light weight aggregate has been the subject of extensive research which affects the strength properties of cement concrete. The industrial by product such as fly ash is a promising material to produce light weight aggregate. By adding small quantities of binding materials like cement and lime to the industrial byproduct i.e. fly ash along with ...
· The surface of sintered artificial lightweight aggregate becomes more vitrified with smooth, porous and rough textures for increasing the binding force between aggregates and cement matrix. The specific gravity for fly ash sintered artificial aggregate is in the range of 1.30–2.35 [4, 6]. Meanwhile, kaolin showed lower specific gravity that ...
Lightweight aggregate has been produced in a laboratory scale rotary kiln. The raw material consisted of class F fly ash with high free lime content. An addition of 8% clay was necessary to get green pellets with sufficient green strength. The basic properties of the produced lightweight aggregate and its behaviour in concrete have been ...
· The artificial lightweight aggregates (ALAs) were manufactured by quick firing using reject ash and dredged soil produced from thermoelectric power plant, and the behavior of radial crack generated in ALAs was investigated. The radial crack is most common in aggregate from reject ash containing 30~90 wt% dredged soil, but the length of crack branches decreased by …
