Lightweight expanded clay aggregate as a building material
LECA is an acronym term of lightweight expanded clay aggregate. It is also known as LIAPOR (porous lias clay), grow rocks or hydrocorns [1]. LECA is produced in Most of these aggregates are light in weight because of the pore structure developed within them during the production stage. Aggregate having a particle density less than 2000 kg/m 3 or dry loose bulk density of less than 1200 kg/m 3 is considered as lightweight aggregates (BSI 92/17688).

The pore size range of the Blue clay aggregates with 10 wt% of tuff (Fig. 8 e) was from 1.51 mm to 4.94 mm. In the case of Grey clay aggregates, the addition of 10 wt% tuff changed the pore size to a range of 0.6 mm–2 mm (Supplementary data Table 3). On the SEM micrographs for perlite and tuff additives, white spots can be seen near the The higher lightness of the expanded clay aggregate EA/1300 was a result of its high firing expansion achieving a density of 0.56 kg/dm 3 (EA/1250 density was 0.85 kg/dm 3); an increase of 50 °C reached a density reduction of 34%. The increase in temperature propitiates a higher expansion due to two factors: an increase of gas An evaluation of the increased expansion of clay aggregates fired

Production of expanded-clay aggregate for lightweight concrete
Artificial LWA are normally produced by using the natural raw materials or byproducts (Güneyisi et al., 2015). Expanded clay aggregate (ECA) is a type of artificially produced LWA that is formed by expanding the natural clay at a high temperature of around 1200 °C in a rotary kiln (Burbano-Garcia et al., 2021; Ozguven and Gunduz, 2012; Pioro Research findings show that LWAC prepared with LECA as coarse and fine aggregate along with 25% fly ash + 10% MSP as cement replacement exhibits good mechanical and thermal properties.(PDF) Influence of Lightweight Aggregates and

Lightweight aggregates from waste materials: Reappraisal of expansion
Introduction. Most Lightweight Aggregates (LWA) currently on the market are manufactured by firing in rotary kilns (at maximum temperatures from 1000 to 1300 °C) natural raw materials like vermiculite, shale, clay, or slate [1].Along with these expanded clay aggregates, LWA are obtained also from naturally-occurring lightweight materials, like Experimental investigation on concrete mix M 20 is done by replacement of cement with fly ash, fine aggregate with bottom ash, and coarse aggregate with light expanded clay aggregate at the rates of 5%, Influence of Fly Ash, Bottom Ash, and Light

Manufacture and performance of lightweight aggregate
Sintering at 1180 °C produced lightweight aggregate with particle density of 1.29 g/cm³, water absorption of 3.6% and compressive strengths of 4.4 MPa. The research showed that lightweight aggregate manufacturing represents a resource efficient option for the reuse of waste drill cuttings and provides significant material saving and The effect of Ca-bentonite as a natural additive on the properties of light expanded clay aggregate was studied. The addition of bentonite is intended to improve the properties of LWA and reduce the energy required for production.
