Lightweight Expanded Clay Aggregate (LECA) is a highly versatile material widely used in construction, horticulture, and environmental engineering. Its unique features, varied specifications, and broad range of applications make it a valuable resource in modern industries. Features of LECA LECA is produced by heating natural clay at high temperatures, resulting in lightweight, porous aggregates with a hard outer shell. It is renowned for its low density, thermal insulation, and soundproofing capabilities. Chemically inert and non-combustible, LECA resists moisture, frost, and chemical attacks, ensuring durability in diverse environments. Its porous structure enables excellent water retention and gradual release, a key advantage in applications requiring moisture control. Specifications of LECA LECA comes in various sizes, typically ranging from 2mm to 20mm in diameter. The material has a density of 300–800 kg/m³, depending on its specific use. It is available in multiple grades tailored for applications such as lightweight concrete, drainage systems, or hydroponic growth media. Applications of LECA In construction, LECA is used as an aggregate in lightweight concrete, reducing structure weight while enhancing thermal and acoustic insulation. It is commonly applied in wall panels, roofing, and flooring systems. For landscaping and horticulture, LECA serves as a growing medium for hydroponics and a soil conditioner, improving aeration and drainage. Additionally, it is utilized in filtration systems, water treatment plants, and geotechnical projects to address drainage and stabilization challenges. LECA’s adaptability, eco-friendliness, and unique properties make it an indispensable material in sustainable development and innovative design solutions.
