Grouts - Cementitious - Sand Free
Product                                                       Description
SikaGrout 300 PT (au) is a non-shrink, cementitious grout with a unique two phase shrinkage compensation mechanism. It is non-metallic & contains no chlorides. With a special blend of shrinkage reducing & plasticizing/water-reducing agents, SikaGrout 300PT (au) compensates for shrinkage in both the plastic & hardened states.
Uses:
  • Horizontal and vertical grouting of ducts within bonded, post-tensioned structures
  • Grout and fill or repair voids within ducts of post-tensioning strand for corrosion protection
  • Grouting with tight clearance requirements
  • Meets RTA B113 requirements
Advantages:
  • Sand free allows filling and repairing of voids within ducts of post-tensioned structures
  • Pre-packaged in accordance with ISO 9001 which ensures consistency of the manufactured material
  • Does not contain aluminium powder or any components which generate hydrogen gas, carbon dioxide or oxygen
  • Silica fume enhanced for low permeability
  • Easy to use…just add water
  • Non metallic, will not stain or rust
  • Zero bleeding, even at high flow
  • Low heat build-up
  • Excellent for pumping
  • Does not segregate, even at high flow
  • No build-up on equipment or hoppers
  • Non-corrosive, does not contain chlorides
  • Superior freeze/thaw resistance
Masterflow 816 is a ready-to-use aggregate free grout specially formulated for applications that require a fluid, shrinkage compensating grout where clearances are shallow, and the grouting of tensioned cables and rods stressed above 550MPa.

Recommended For:

  • Shrinkage compensated grouting in restricted spaces between precast wall panels, beams and columns where grout will be in contact with highly stressed steel
  • Grouting of anchor bolts, rods and pipes where the annular space is too small for conventional aggregate containing grouts (clearances of 6 to 25mm)
  • Repairs to concrete, such as cracks and honeycombing, filling small voids
  • Pumping into areas around pre-tensioned or post-tensioned cables and rods to encapsulate the steel and protect it against corrosion, and to provide maximum anchorage
  • Placing around end sections of unanchored cables and rods to provide anchorage for subsequent tensioning
  • Grouting cable anchor plates or other types of plates where grout will be in contact with highly stressed anchorages
Features & Benefits:

  • Pumpable - into areas inaccessible to conventional grouts or grouting methods.
  • No bleeding or settlement shrinkage.
  • Long open time - can be pumped and/or recirculated for relatively long periods of time.
  • Non shrink - hardens without shrinkage within the sheath or hole ensuring maximum bond and protection against ingress of water while in service.
  • Specially formulated - to enhance flow and protect stressed tendons, bolts or bars from corrosion.
Alofix MC is an ultra-superfine, economical, injection cementitious grout, for stabilising and strengthening soil / sand substrates. Alofix-MC is an inorganic grouting material composed of ultra-superfine particles, and as a grout has excellent permeability, strength and durability. It is suitable for sealing and/or stabilising sandy soil foundations, and especially for grouting soils for permanent structures such as foundations, tunnels, dams, oil tanks etc.

Advantages:

  • No soil polluting properties - consists entirely of inorganic materials ensuring no pollution of underground water or soil
  • Remarkable penetrating abilities - the average particle size of Alofix-MC is 4 microns with a grain size distribution finer than 12 microns. The specific Surface Blaine fineness of 8150 cm2 / g, enables penetration comparable to chemical grouts
  • High hardened strength - the ultra fine grains of the Alofix-MC are chemically activated, so that curing provides rapid hardening to a high strength. This initial hardening is followed by further hardening during an extended period
  • Excellent durability - after hardening by hydration, Alofix-MC acquires impermeability, which protects it from underground and sea water, to ensure extremely long durability
  • Easy handling - with its strong dispersive quality, Alofix-MC is highly resistant to separation and sedimentation, which provides protection against damage for the injection equipment, and prevents obstruction of pipework
  • Fast set time - the set time of Alofix-MC is generally between 4 - 8 hours
