Lightweight Concrete Roof Topping

Elastizell roof decks have numerous wind uplift fire and seismic ratings with both mechanically fastened built up.

Lightweight concrete roof topping.

Floor top stg is specially designed to smooth out uneven rough or minor deteriorated interior concrete floors. This paper aims to detail the properties of bst lightweight concrete and how it is used as a floor or roof topping. Profiles are a fraction of the weight of our conventional roof tiles and are perfect for re roof projects. Zic nvs insulcel and zonocel.

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. Lightweight concrete roof tile eaglelite is our lightweight fire safe roof tile that is available in some of our most established profiles and colors. Elastizell roof decks are cast over galvanized steel decking corrugated or fluted precast or cast in place concrete and wood. 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.

Each design encapsulates the insulation board in insulating concrete. Roof decks engineered fill floor fills for more than 50 years the elastizell corporation of america has researched developed tested and improved the elastizell roof deck system. In this article we study about the work procedure of laying topping concrete its types and advantages. The shape of profiled steel decking may vary as shown in fig 3 and fig 4.

Our sub six profiles and our flat lightweight 720 lbs. Siplast lightweight insulating concrete is available in four mix designs. Contents work procedure of hellip. Vermiculite grades vary from coarse to superfine.

It offers the advantages of strength durability and light weight. The four designs represent a range of compressive and tensile strengths allowing a choice of system based on substrate and specific project circumstances. 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 concrete is then poured over the eps on the following day.

Elastizell concrete is produced by mixing elastizell expansion material into a properly designed cementitious mixture. 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. Lightweight concrete can also be applied as a topping slab over structural concrete decks.
