ribbloc
The LiteConcrete solid ribbloc is designed as a superior, lightweight alternative to conventional hollow concrete rib blocks. Our ribbloc's increased width (700mm rib centres) reduces concrete rib requirements by 30%. Half the number of blocks are required to pack the deck (four per square meter), and their lightweight nature makes them quick and easy to install. They also require 20% fewer supporting props. All these benefits guarantee more economical installations for our clients. There is no better solution for a high-performance rib-and-block concrete slab (see the comparison below).
Furthermore, as with all our blocks, the rib blocks are manufactured from recycled waste material, offering an eco-friendly alternative.
Comparison between LiteConcrete Ribbloc and convention rib blocks on a 100-square-meter rib-and-block slab
LiteConcrete solid ribbloc for 100-square-meter rib-and-block slab:
- Total number of LiteConcrete rib blocks required: 400
- Total block weight: 5,500kg
- Rib weight: 2,345kg (30% fewer ribs)
- Concrete weight: 24,000kg (10 cubes)
- Total finished deck weight: 31,845kg (31,8 tons)
Conventional hollow concrete rib block for 100-square-meter rib-and-block slab:
- Total number of blocks required: 862
- Total block weight: 12,068kg
- Rib weight: 3,350kg
- Concrete weight: 26,400kg (11 cubes)
- Total finished deck weight: 41,818kg (41,8 tons)
The total weight savings on a 100-square-meter rib-and-block slab when using LiteConcrete rib blocks would be 10 tons – an effective dead weight saving of 100kg per square meter.
