Features and benefits
Lightweight concrete
Using Lytag coarse aggregates reduces the weight of structural concrete by around 23% compared with natural aggregate concrete. Including Lytag fine aggregate allows further weight reductions of up to 32%
Advantages: Dead load of structure reduced, less foundations needed
Benefits: Significant cost savings
Excellent structural performance
Lytag lightweight aggregate concrete can provide the same level of structural performance as normal weight concrete so it can be used in exactly the same way
A compressive strength of up to 65N can be achieved
Advantages: Meets all British & European Standards at a fraction of the weight. Including a 16% improvement on long-term deflection over normal weight concrete
Benefits: Same performance as natural aggregate concrete, reduced costs, greater design flexibility
Installation, as easy to place as normal concrete
Placing and compaction is as easy as with normal weight concrete. Lytag concrete can be pumped long distances and to great heights, as proven by its use in numerous recent structures such as the Shard and 20 Fenchurch St (the Walkie Talkie). Finishing processes used for normal concrete can easily be applied to Lytag concrete
Advantages: No specialist skills or tools needed. All possible concrete finishes can be achieved. High flow values achievable aiding speed of placement and workability
Benefits: No extra cost for normal installations
Insulation, 100% improvement in thermal conductivity
Using Lytag® not only reduces the density of your concrete but also improves the insulating properties with double the thermal performance of normal weight concrete. It meets all rating requirements
Advantages: Reduced value leading to improved U value of elements within the structure
Benefits: More thermally efficient structures; reduction in cold bridging
Fire Resistant, 20% more fire resistant than natural aggregate concrete
Lytag® pellets experience extreme temperatures during manufacture. As a result they are more stable at high temperatures, have a lower expansion coefficient, and a lower reduction in strength. This makes Lytag® ideal for fire resistant applications such as lift shafts and tunnels
Advantages: Meet all ratings at a reduced cost
Benefits: Increased overall fire safety of structures
Design, greater design opportunities
Lytag allows architects and structural engineers to push the boundaries of design by including longer cantilevers, slimmer general sections, larger spans and fewer or smaller columns
Advantages: Less constraints on design, larger floor spaces
Benefits: More available space for the client to utilise, architects and engineers can gain a competitive advantage at the tender stage.
