Lightweight Expanded Clay Aggregate Leca for Concrete Lightweight Panel

Product Description

Lightweight Expanded clay Aggregate LECA for Concrete Lightweight Panel

LECA (Light Weight Expanded Clay Aggregate) is a Lightweight Expanded Clay, formed by the heating and firing of clay in a rotary kiln, at temparatures of up to 1150°C. The process transforms the clay into various lightweight ceramic granules, which have a hard ceramic shell and a porous core.
Product name: Lightweight Expanded Clay Aggregate ( LECA) 
Other Name: Ceramsite, Expanded Clay, Clay Pebble, Clay pellet, Clay balls.
Main Sizes:  -1-4mm(1-3mm), 4-10mm(3-9mm), 8-10mm, 8-16mm, 10-30mm etc.
Characteristic:
 Made of 100% natural clay. Pebbles are of uniform, round shape. 
 Inert, pH-neutral, clean and decorative.

LECA can applies widely for:

• Insulation
• Bulk filling
• Pre-cast panel / Unit bath / Facade
• Building blocks
• Composite section construction
• Partition wall, sound insulation, heat insulator and moist barrier
• Concrete panel etc.

Usages and requirement of LECA lightweight concrete is similar to those of the normal concrete.
The structure of LECA lightweight concrete is similar to the normal concrete, mixing with LECA sand (or light sand), cement and water. With proper and sufficient vibration, low air content exist within LECA lightweight concrete and this can also against the corrosion of steel reinforcement. Suitable additives can be added into LECA aggregate concrete.
