Lightweight concrete is as name suggests lighter in weight than standard concrete. Lightweight concrete gained attention of structure designers as it allows lighter structure and other superior properties.
Lightweight Concrete has some noble properties-[edit | edit source]
- Higher thermal resistance - This type of concrete is more fire resistant than ordinary bricks.
- Less water permeability - This will give damp-proof construction.
- Speed in construction - We can mold lightweight concrete into any desire shape so it will expedite construction speed.
- Lightweight implies less weight on foundation.
- Higher strength of lightweight concrete than ordinary bricks make structure more strong.
Methods to make Lightweight Concrete-[edit | edit source]
- By use of foaming admixture
- By use of Low density aggregates
- By eliminating the fine aggregate from concrete
