2. HOW LIGHT-WEIGHT CONCRETES ARE CLASSIFIED

Due to its compressive strength and volumetric weight, the light-weight concretes are classified into three main groups:

1. Structural light-weight concrete:

Volumetric weight (dry) 1400 to 1850kg/m (2341 to 3108 ib/yd)
Compressive strength: 175 kg/cm or more (250 PSI)

2. Moderate strength light-weight concrete:

Volumetric weight (dry) 300 to 800 kg/m (504 to 1344 ib/yd)
Compressive strength 60kg/cm or more (857 PSI)
Reference normal concrete weight is 2400 kg/m (4032 ib/yd)

3. Insulating light-weight concrete:

Volumetric weight (dry) 800 to 1400 kg/m (1344 to 2341 ib/yd)Compressive strength 60kg/cm or less (857 PSI)
