Expanded clay aggregate - Wikipedia
Lightweight expanded clay aggregate (LECA) or expanded clay (exclay) is a lightweight aggregate made by heating clay to around 1,200 °C (2,190 °F) in a rotary kiln. The heating process causes gases trapped in the clay to expand, forming thousands of small bubbles and giving the material a porous structure.
Lightweight Expanded Clay Aggregate LWA | Laterlite
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 ...

Lightweight Aggregate - ESCSI
ESCS is a ceramic material produced by expanding and vitrifying select shales, clays, and slates in a rotary kiln. The process produces a high quality ceramic aggregate that is structurally strong, durable, environmentally inert, low in density and highly insulative.
Leca Asia – Light Expanded Clay Aggregate
Expanded clay aggregates are porous ceramic products with a uniform pore structure of fine, closed cells and with a densely sintered, firm external skin. It is manufactured in rotary kilns from raw materials containing clay minerals.

Expanded clay can reduce the weight of concrete by almost 50% without compromising strength. It is 4-5 times lighter than loose gravel or loose fill crushed stone. It can be used as loose fill and insulation in road and rail embankments and can sustain dynamic loads from heavy high-speed trains. Expanded clay is 100% recyclable or reusable.
Expanded clay concrete blocks: sizes, pros and cons
Expanded clay concrete blocks come in sizes that blend in perfectly with other finishing options, greatly enhancing quality and cutting down on construction time. Expanded clay concrete blocks combine remarkable strength and insulation with lightweight qualities, making them a versatile and environmentally friendly building material.
Walls - EXCA
Expanded clay blocks are largely used in structures exposed to earth pressure. The durability against moisture, frost resistance, low thermal conductivity and high mechanical strength makes expanded clay blocks a superior product for this challenging application.
