Lite Weight Concrete Floor

Please send us information regarding the proper chemical to use to achieve the proper mix for the lightweight concrete.

Lite weight concrete floor. These floors are constructed for different purposes but the reduction of dead loads on the structure is. To make this concrete combine 8 parts cement sand and lightweight aggregate with 5 parts water. Lightweight concrete floor provides more efficient strength to weight ratio in concrete floor systems when compared to other conventional concrete floor systems. The other option is a wood structure with assumed 2 layers of 3 4 subfloor vapor barrier and then 2 3 of light weight concrete.

We are building a 2 story condominium complex with concrete slab on grade. The light weight concrete density is less because lightweight coarse aggregates and sometimes lightweight fine aggregates are used which make the concrete weigh less. A structural light weight concrete mix has a density of about 105 pounds per cubic foot compared to normal concrete with a density of 150 pounds per cubic foot. For the second story a foamed type of lightweight concrete is being used over plywood for sound absorption between floors.

Plus rebar and concrete. The reduced quantity of concrete and steel reinforcement offsets the marginally higher cost of lightweight concrete floor systems. An example is lite deck which costs around 3 25 sqft of floor surface for the form.
