Lightweight Concrete Roof Topping

This paper aims to detail the properties of bst lightweight concrete and how it is used as a floor or roof topping.

Lightweight concrete roof topping.

Siplast lightweight insulating concrete is available in four mix designs. Description floor top stg is a standard traffic grade single component shrinkage compensated self leveling floor topping and underlayment that may be pumped or poured. Lightweight concrete can also be applied as a topping slab over structural concrete decks. Floor top stg is specially designed to smooth out uneven rough or minor deteriorated interior concrete floors.

Each design encapsulates the insulation board in insulating concrete. In laf s case lightweight concrete toppings are predominantly blends of vermiculite aggregates mixed with cements of various grades depending on the use. Not only does the deck acts as a permanent formwork to the concrete but also provides adequate shear bond with the concrete. Topping concrete is defined as a layer of high strength concrete placed on an old worn out concrete surface to provide a dense abrasion resistant surface to increase structural depth and strength of the base concrete.

The lightweight concrete is then poured over the eps on the following day. Profiles are a fraction of the weight of our conventional roof tiles and are perfect for re roof projects. In this article we study about the work procedure of laying topping concrete its types and advantages. Elastizell roof decks are cast over galvanized steel decking corrugated or fluted precast or cast in place concrete and wood.

Lightweight concrete roof tile eaglelite is our lightweight fire safe roof tile that is available in some of our most established profiles and colors. As a floor or roof topping bst lightweight concrete has been used for many new and redevelopment projects. The shape of profiled steel decking may vary as shown in fig 3 and fig 4. Elastizell concrete is produced by mixing elastizell expansion material into a properly designed cementitious mixture.

The four designs represent a range of compressive and tensile strengths allowing a choice of system based on substrate and specific project circumstances. Our sub six profiles and our flat lightweight 720 lbs. Zic nvs insulcel and zonocel. Lightweight concrete can also be applied as a topping slab over structural concrete decks.

In lwic applications the eps board is set in a slurry coat of lightweight concrete and allowed to set up for up to 24 hours. Contents work procedure of hellip. It offers the advantages of strength durability and light weight. Elastizell roof decks have numerous wind uplift fire and seismic ratings with both mechanically fastened built up.
