2021-12-27 Lightweight expanded clay aggregate (LECA) is a manufactured aggregate with many uses in construction, such as aggregate for the lightweight concrete or like geotechnical fill. This process was done at atmospheric pressure for both unbroken and broken grains and with a vacuum hood for unbroken grains. Download : Download high-res image (288KB)get price
Laterlite Expanded Clay is a lightweight aggregate (LWA), with insulating characteristics made by expanding special natural clays at high temperature (1200°C).Laterlite Expanded Clay is manufactured in different types and sizes, in granular or crushed form, standard (lighter and insulating applications) or structural (high mechanical strength applications).get price
2018-2-20 The use of waste clay generated by major infrastructure development projects to make lightweight aggregate has a positive environmental impact and contributes towards a more circular economy. This paper reviews the manufacturing process used to produce lightweight aggregates from clay and the influence of processing conditions on properties.get price
Lightweight aggregates serve the function of dimensionally stable aggregates with suitable density and water absorption and can be prepared from sludge through sintering processes (Huang et al., 2001 ). Huang and Wang (2013) manufactured these aggregates and investigated their structural and nonstructural properties.get price
2018-5-10 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 many countries (more than twenty countries) with various products name. Particular countries produce LECA with approximately similar method such as UK, Iran, Portugal, Finland, Germanyget price
