Lightweight Concrete Floor Thickness

Plus rebar and concrete.

Lightweight concrete floor thickness.

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. Lightweight concrete after being placed in a drying oven at 230 9ºf 110 5ºc for a period of time sufficient to reach a density that changes less than 0 5 in a period of 24 hr. The thickness of solid lightweight concrete floor system is determined according to the specifications of aci 318 14 as discussed in the following sections. The light weight concrete density is less because lightweight coarse aggregates and sometimes lightweight fine aggregates are used which make the concrete weigh less.

It is used in the construction of multistory buildings. We would like to show you a description here but the site won t allow us. Because lightweight concrete is typically thinner it is made. If one uses a lightweight concrete weighing 90 pounds per cubic foot a 1 1 2 inch thickness of this concrete weighs about 11 pounds.

Suspended floors have been benefiting from lightweight concrete for years as it reduces the weight on the structure and increases fire resistance. Most notably renzo piano s the shard a marvelous 95 floor structure made of lightweight concrete that took only four years to build. 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. Lightweight the generic name of a group of aggregates having a relative density.
