Concrete Repair Mortars

Weber.cem HB40

Acrylic-polymer modified high-build structural repair mortar.

Uses:

  • Structural concrete repairs, particularly where high, overhead  build is required
  • Repairs to bridge and highway structures
  • Repairs to car park soffits, bridge decks and columns

Features & Benefits:

  • Lightweight, low-density structural repair mortar which allows speedier completion of work
  • High-build properties – up to 100 mm vertically and 75 mm in a soffit repair, without formwork
  • Compatibility with concrete greater than 30 N/mm2
  • Unique shrinkage compensation system provides long-term dimensional stability. Less than 0.02% shrinkage at 28 days
  • Contains fibres and spray dried acrylic polymer
  • Low permeability to water, carbon dioxide and chlorides
  • Easy to apply, with excellent application properties
  • Complies with Department of Transport Departmental Standard BD 27/86
  • Agrément approved as part of the weber.cem Concrete Repair System

Technical data:

All test results were obtained at 20°C, unless otherwise stated. 2.55 litres of water per 20 kg bag

  • Compressive strength* 7 days 25 N/mm2 28 days 40 N/mm2
  • Flexural strength 28 days 5.3 N/mm2
  • Tensile strength 28 days 3.3 N/mm2
  • Dynamic modulus of elasticity 28 days 15.0 kN/mm2
  • Drying shrinkage (25 x 25 x 285 mm prisms) 28 days < 200 microstrain 25°C, 50% RH
  • Carbon dioxide barrier, equivalent concrete 250 mm thickness at 10 mm (Taywood method)
  • Water absorption ISAT (BS 1881-208:1996) 10 min. 0.02 ml/m2/sec
  • Fresh wet density > 1500 kg/m3
  • Working time 30 – 45 minutes

* Value obtained in laboratory conditions.
Achievement at 28 days strength is dependent on site conditions, water addition and application technique.
Typically, compressive strength will vary between 35 and 45 N/mm2 at 28 days
