2. EABASSOC LIGHTWEIGHT FOAMED CONCRETE
Made from Sand, Cement, Water & Foam
Dry Densities from 400 to 1600 kg/m3
Compressive Strengths from 1 to 15 MPa
Mix Designs chosen to optimise density, strength and cost

3. Advantages of Foamed Concrete
Lightweight...does not impose large loadings
Does not settle
Free flowing
Enables Fast Work
Excellent load spreading characteristics
Reliable quality control
Once placed requires no maintenance
Low water absorption over time
Resistance to freeze-thaw cycle
Non-Hazardous

4. Typical Uses for Roads Trench Reinstatement Road Widening (Sub-Base)
Road Building on Soft Ground (Sub-Base)
Road Repairs
Bridges over Drainage Channels

5. Road Widening

6. Road Sub-Base

7. Principle of Roads on Soft Ground
Soft Ground = X kg
Soft Ground
Wearing Course = Y kg
Foamed Concrete Road Base = Z kg Y X + Z =
