This work presents the production of expanded clay aggregates (EA) by firing at 1300 °C (EA/1300), a high temperature for EA production. Therefore, the material was produced in an attempt to maximize lightness. Initially, it was characterized the natural clay and the expanded clay aggregate. The EA/1300 had a density of 0.56 kg/dm 3 and a …

Light Expanded Clay Aggregate (LECA) Brief Introduction. LECA consists of small, lightweight, bloated particles of burnt clay. The thousands of small, air-filled cavities give LECA its strength and thermal insulation properties. The base material is plastic clay which is extensively pretreated and then heated and expanded in a rotary kiln.

ECA® is an engineered product designed to provide a plethora of benefits in varied sectors. ECA® stands for Expanded Clay Aggregate. It is a type of lightweight aggregate made from natural clay. The clay is pelletized and then processed in rotary kilns at temperatures of up to 1200°C (2192°F). This causes the clay to expand into lightweight ...
The strength of activated fly ash-based artificial lightweight aggregate by inclusion of geopolymer is comparable to that of commercialized expanded clay lightweight aggregate [ 22 ].
Thanks to its mechanical strength and low density, Laterlite Expanded Clay is the ideal aggregate for lightweight structural concrete batching.

Most commonly, this has been done through the use of light-weight, porous aggregates, such as expanded clay, shale, slate, natural pumice, and perlite aggregates,4or the inclu-sion of excessive air through the use of open graded aggregate mix or ing agents.
Henan Zhengzhou Mining Machinery Co.,Ltd has started the Light Expanded Clay Aggregate (LECA) equipment manufacturing since company foundation. We always trance the new technology developing on the LECA equipment manufacturing and have cooperate with the college and R&D institute to improve the equipment performance and function.
LECA is round compressed coarse aggregate-like structure which is manufactured by burning natural clay at 1200 °C. It is hard and is full of voids which are interconnected to form a honeycomb-like structure within the aggregates. The aggregate size varies from 0 to 30 mm and depending on the final use these aggregates are …

Light expanded clay aggregates (LECA) have been increasingly used as substrate material for constructed wetlands given their phosphate removal capacity, mechanical strength, hydraulic conductivity and their plant rooting and biofilm growth supporting structure. This review summarizes the current literature on LECA-based …
This research examines the petrology of sintered industrial sludge–marine clay aggregates in order to better understand the mechanisms leading to pyro-expansion and bloating of the aggregates. The study would enable development of an efficient and cost-effective bloating methodology for lightweight aggregate production.

The residual compressive strength of eight lightweight concrete mixtures containing three commercial grading (Liapor HD 5 N, Liapor HD 7 N, and Liapor 8F) of coarse lightweight aggregate (LWA) were determined after to expose at high temperatures. Eight mixes were produced, two by normal weight aggregate and the rest by different …
The ASTM standards have an explicit list of LWA covered: "Two general types of lightweight aggregates are covered by this specification: aggregates prepared by expanding, pelletizing, or sintering products such as blast-furnace slag, clay, diatomite, fly ash, shale, or slate; and aggregates prepared by processing natural materials, such as ...
Lightweight aggregates are used to produce lightweight concrete when the weight of aggregates, is lower than 1200 kg/m3. Lightweight aggregates have many sources: natural materials such as shales, clays, pumice, diatomite, volcanic cinders, and slates or artificial materials (by-products) such as iron blast furnace slag, clay, sintered …
