ü LFC is cementatious material integrated with mechanically entrained foam in the mortar slurry which can produce a variety of densities ranging from 400 to 1600 kg/m3. The application of LFC has been primarily as a filler material in construction works. In order to develop thermal property model, LFC is treated as a porous material and the effects of radiant heat transfer within the pores are included. ü Extensive compression and bending tests at elevated temperatures were performed for ...
The building system uses pre-cast Ferro cement roofing channels of a segmental arch profile which are placed adjacent to each other and spanning. over two supports. After partly filling the valley between channels with concrete, the channels form an idealized T-beam and are able to carry the load. of a roof / floor.

1. Pre-stressed Beams From Reinforced Concrete to Pre-stressed Applications 2 The Disadvantages of R/C Reinforced Concrete does have shortcomings 3 Concrete Beams require a large amount of formwork Timber is expensive The shuttering is afterwards mostly thrown away A lot of material is wasted for props and supports 4 R/C Formwork is Time Consuming Fabrication takes a long time Craftsmen are ...
Used together, Siplast SBS-modiﬁed bitumen roof membranes and Siplast Lightweight Insulating Concrete Systems result in a longer lasting roof. And, since Siplast Lightweight Insulating Concrete Systems are reroofable, signiﬁcant cost savings over the life of the building can be realized.
Foamed concrete is also much lighter than slopes made from mortar screeds. This means that a roof with a slope made of foamed concrete has a lower loading on the structure of the building. Properties of Foamed Concrete used for Roofing Typically the foamed concrete is made with dry densities of between ~ 400 and ~ 600 kg/m3.
Foamed Concrete Screeds. The high air content of foamed concrete screeds make them ideal for use as floor and roof screeding materials where the lightweight nature of the materials reduce deadloading on the structure whilst achieving outstanding excellent thermal efficiency. The material can be laid to fall at thicknesses from 50mm to 1000mm in any one application, can be easily pumped, laid and finished.
