Main benefits
The use of zeolite in construction materials provides technical, economic, and environmental advantages.
How does zeolite work
in concrete?
Zeolites are porous aluminosilicates and therefore natural pozzolans. They can be used to replace up to 40% of the cement in Portland cement concrete to make lightweight concrete with specific properties.
Concrete can be made with a compressive strength ranging from 5 to 30 MPa, and density ranging from 500 to 1500 kg/m3.
Improved setting
and durability
The porous structure of natural zeolite holds water which can increase curing time and increase strength during curing.
Zeolites also have much higher cation exchange capacities than other natural pozzolans and this limits, or totally prevents the alkali-silica reaction.
Energy savings and
emission reduction
The use of 10 tonnes of zeolite saves approximately one tonne of fuel.
Lightweight aggregates and new materials
Zeolite can be expanded by heating to around 1200ºC to produce lightweight aggregate with a density of around 0.8 kg/cm3. This can be used to make lightweight blocks for construction, or decorative wall panels for example.

Lightweight construction elements
Natural zeolite is also used in the production of ceramics, glazes, and frits, a field in which scientists continue to explore its full potential.
Sustainable construction
and innovation
The construction sector is highly dynamic and increasingly demands high-tech and energy-efficient materials.
Natural zeolite stands out as a raw material with great potential for developing new, more sustainable, efficient, and environmentally friendly construction materials.
The use of zeolite in construction materials and ceramics continues to be the subject of ongoing research and innovation.
