Features & Benefits

• Uses:
  • Crane rail tracks
  • Stanchion bases
  • Vibrating machinery bed plates
  • Ground anchors
  • Bridge bearing seats
  • Off shore structures repairs
  • Wind turbines bases
  • Underwater grouting projects
• Ultra high strength grout specially formulated using a Portland cement powder mix
• Blend of fine and ultra-fine cements, high quality graded sands and a set of synergistic admixtures
• Special shrinkage compensating components, which give a non-shrink grout in both the plastic and hardened states
• Powerful plasticising agents produce a highly flowing grout at low water content
• Exhibits highly anti-washout properties and is ideal for underwater applications
• May be safely used in contact with reinforcing steel and structural steel elements due to its very low chloride content
• Specialised mix design enables placement at low water content leading to good freeze-thaw stability, low water absorption plus resistance to oil, sea water and mild alkali attack
• Suitable for pumping applications, pumping trials are recommended prior to site application to ensure pumping equipment is suitable
• 100 Newton Grout AW has been tested in accordance with the appropriate parts of the following standards:
  • EN 12390, EN 196, EN 1015
  • Corps of Engineers Specification for Non Shrink Grout CRD C621

Application

Preparation

Formwork should be erected and made grout-tight. The formwork must be designed with sufficient hydrostatic head to ensure grout flow into and across the grouting area. Saturate the grouting area with water. Leave for 1 hour and then blow out any surplus water

Mixing

Pour the required quantity of clean water (4.5 litres per 25 kg bag or 180 litres per tonne) into the mixing vessel for each complete unit of 100 Newton Grout AW to be used. Slowly add the powder to the water whilst continually mixing. Mechanical mixing should be carried out using either a high torque slow speed drill with a Grout Stirrer or a grout mixer set on slow speed for small mixes, or for larger mixes forced action type mixers (High speed or colloidal mixing may cause thixotropy leading to loss of flow). This material is not suitable for mixing by hand. It is of utmost importance that the product is mixed thoroughly enough that a grout consistency is obtained without the addition of further water. Fresh grout should be allowed to stand until the air entrapped by mixing has been released.

Placing

Grout should be placed within 10 minutes of mixing or 60 minutes if kept mobile prior to placing. Continuous placing is important, pouring or pumping from one side of the form until the grout appears at the opposite side of the grouting area. Do not disturb once grouting has been completed. 100 Newton Grout AW may be placed at temperatures between 5°C and 35°C.

Curing

Placed grout, which is exposed, should be cured in accordance with good concrete practice including water spray or the spray applied curing membrane Polycure.
