Technical Specification
Manufacture
Betaloc blocks are manufactured to fine tolerances
using aggregates complying with BS EN 12620 and
cement to BS EN 197.
Dimensions,
Weights & Tolerances
Betabloc blocks achieve a minimum compressive
strength of 7.3 N/mm and are available in the following size.
450mm long x 225mm high x 225mm wide - approx.
weight = 20 kg.
Manufacturing tolerances length, height &
width + 2mm or - 2mm.
Fire
Resistance
Minimum fire resistance of Betaloc blocks: 1 hour |
Resistance
to Sulphate Attack & Frost Damage
The standard concrete in filled Betaloc wall system
is resistant to ACEC Class AC-1.
Sulphates in accordance with BRE Special Digest
1 and has adequate resistance to freeze / thaw
conditions.
Concrete
Infill
The Betaloc block wall system is bonded with insitu
concrete, which is placed down through the inter-connected
pockets in the dry bonded blocks, together with
steel reinforcement to form a composite section
with high vertical and lateral load resistance.
The concrete infill is to be design strength class
C25/30 in accordance with the requirements of
BS 8500 using 10mm maximum size aggregate, minimum
cement content of 300 kg/m OPC and a free water
cement ratio of 0.55. |
