Notes

1. Deck and beam deflection (ie, ponding) is not included in the table.

2. Deck and mesh weight is not included in the weight of concrete figures.

3. British Standard density of concrete is taken as:

Normal weight (wet) 2400 kg/m3

Normal weight (dry) 2350 kg/m3

Lightweight (wet)     1900 kg/m3

Lightweight (dry)     1800 kg/m3
