Roof Slabs, Decks and Beams, as well as all structural elements of a roof, can be constructed or strengthened with lightweight structural concrete, reducing structural dead load by up to 40%.
The construction of the load-bearing structure of the roof slab with expanded clay based structural lightweight concrete offers several advantages, whether in renovation or building extension in height.
With structural lightweight concretes, it is possible to create structural elements with longer spans and slimmer cross-sections, thanks to the low self-weight combined with high strengths. This combination of low weight and strength allows greater freedom of design and opportunities architectural expression.
Loadbearing roof structures that incorporate Laterlite lightweight structural concrete – see Latermix Beton range – can reduce structural loading by up to 40%: this is particularly useful for preventing overloading at the tops of buildings in seismic zones, in refurbished buildings, or in extensions or upper storeys added to buildings. In addition, thermal bridges are reduced, due to the lower conductivity of expanded clay structural concrete (lambda up to 4.5 times lower than that of traditional concrete).
Trafficable roofs for vehicular traffic.
The excellent loadbearing capacity of Latermix Beton 1600 makes it suitable for hardwearing industrial concrete flooring surfaces (with power float finish + dry shake quartz surface hardener) carrying vehicle traffic and is ideal for rooftop car parks and as a walkable protection for waterproofing.
Lightweight structural concretes are available as bagged dry premixes (Latermix Beton 1400, 1600 and 1800). For largescale works, they can be manufactured in concrete plants or in pre-fabrication plants from structural expanded clay aggregates.
All these application possibilities highlight the benefits of the specific characteristics of Laterlite Expanded Clay LWA as well as Latermix premixes: durability, stability, non-combustibility, resistance to high temperatures, etc.
