The thermal conductivity of LECA is lower than normal weight aggregates, since LECA has a lower density and a more porous structure than normal-weight aggregates. This leads to less thermal conductivity and higher thermal insulation.
In addition to its low density, Leca LWA promote high durability and mechanical resistance, suitable for high perfor-mance concrete. Ready mix and precast LWAC can be produced with many densities and with characteristic compressive strength up to 70 MPa, or even higher. Leca International is today manufacturing Leca LWA at seven plants
LECA increased the density of concrete and hence increased the compressive strength of concrete. LECA enhanced the fire resistance of concrete due to its low thermal expansion and …
Leca is produced of clay with poor lime content, which is dried and fired in rotary kilns. The kilns shape the clay into pellets and at a temperature of 1.150 oC gas is formed. The gas expands the pellets resulting in high porosity and lowweight properties.
Expanded clay combines low density with high strength. In addition, the aggregate holds many other important characteristics, and it can be described as an "all-in-one" product, providing a huge range of properties vital for sustainable construction.
LECA increased the density of concrete and hence increased the compressive strength of concrete. LECA enhanced the fire resistance of concrete due to its low thermal expansion and exposure to high temperature at the time of manufacturing. The resistance to freezing and thawing was reduced

The principle of the production of LECA by the expansion method is that the tailings rich in clay can be gradually softened at high temperature, and have a certain viscosity, and can flow and deform under the action of external …

Some factories can produce higher density material with considerably higher particle strength with bulk density up to 800 kg/m3. In general, the particle strength is dependent by the particle density. A high density LECA has a considerably higher strength than a low density material when manufactured at the same site and with the same raw ...
Low density: Due to its porous nature, sintered-expanded material typically has a density of 300–500 kg/m 3, half that of regular sintered aggregate. Its lightweight property makes it suitable for low-density construction and decoration industries.
