WHAT ARE CLASSIFICATIONS OF CONCRETE?

 Based on unit weight   

ü Ultra-light concrete   <1,200 kg/m³

ü Lightweight concrete 1200- 1,800 kg/m³

ü Normal-weight concrete ~ 2,400 kg/m³

ü Heavyweight concrete > 3,200 kg/m³

 Based on strength (of cylindrical sample)

Ø Low-strength concrete < 20 MPa compressive strength

Ø Moderate-strength concrete   20 -50 MPa compressive strength

Ø High-strength concrete 50 - 200 MPa compressive strength

Ø Ultra high-strength concrete > 200 MPa compressive strength

 Based on additives: 

§  Normal concrete

§  Fiber reinforced concrete

§  Shrinkage-compensating concrete

§  Polymer concrete
