Lightweight Concrete

Lightweight Concrete

Lightweight concrete by CEMEX incorporates advanced admixture technology with a special aggregates to produce mixes with much lower densities than normal concrete. Structural concretes of up to 50N/mm2 compressive strength can be produced with a dry density of 1900kg/m3 and non structural mixes can be produced with densities as low as 1000kg/m3

Reduction of weight

✓ Up to 60% lighter (Non structural)
✓ Up to 25% lighter (Structural)

Superior fresh properties

✓ It can be pumped
✓ It can be placed finished an compacted like normal concrete

Improved fire resistance (Structural)

✓ Aggregate stable at high temperatures

Environmental friendly

✓ Recycled materials
✓ Can help to reduce steel and foundation size in structure

Project Spotlight

Dubai International Airport - Dubai

CEMEX supplied over 10,000m3 of LIghweight Structural concrete for the mezzanine levels of this prestigious construction project, allowing for greater spans between columns, maximizing space within the structure without sacrificing structural performance.
