Lightweight Concrete Floor Topping Weight

We are building a 2 story condominium complex with concrete slab on grade.

Lightweight concrete floor topping weight.

Topping the list is the change in flooring adhesives composition due to the now government regulated use of hazardous materials and volatile organic compounds vocs. The reduced quantity of concrete and steel reinforcement offsets the marginally higher cost of lightweight concrete floor systems. These floors are constructed for different purposes but the reduction of dead loads on the structure is. The mixes may be used for floor or roof toppings and have great benefits in terms of strength durability impact resistance and low weight.

The lightweight aggregates used are usually expanded shale clay or slate materials that have been fired in a rotary kiln to give them a porous structure similar to volcanic rock. The weight advantage of lightweight concrete may provide the best benefit but the same feature that reduces the weight the pores in the aggregate or foam or in the air introduced during mixing also become additional spaces within the concrete that can trap and retain moisture. Several elements contribute to the failure of flooring systems whether the slab is composed of lightweight or normal weight concrete. In laf s case lightweight concrete toppings are predominantly blends of vermiculite aggregates mixed with cements of various grades depending on the use.

The light weight concrete density is less because lightweight coarse aggregates and sometimes lightweight fine aggregates are used which make the concrete weigh less. For the second story a foamed type of lightweight concrete is being used over plywood for sound absorption between floors. We deliver a high level of acoustic control for interior privacy not just for residential structures but any light weight construction where airborne iic or structural noise transmission stc can be an issue. Floor top stg is specially designed to smooth out uneven rough or minor deteriorated interior concrete floors.

Most gypcrete products cure much more quickly than conventional concrete which takes up to 28 days to cure unless a cure accelerant is used. Lightweight concrete floor provides more efficient strength to weight ratio in concrete floor systems when compared to other conventional concrete floor systems. Gyp crete floor underlayment is one of the most efficient fire and sound control products available for multifamily construction. Sound floors offers lightweight sound reduction concrete.

Floor top stg is a standard traffic grade single component shrinkage compensated self leveling floor topping and underlayment that may be pumped or poured.
