SikaGrout®-300 PT MX

High-performance, zero-bleed, sand-free, cementitious grout for post-tensioned structures

SikaGrout®-300 PT MX is a non-shrink, cementitious grout with a unique 2 stage shrinkage compensating mechanism. It is non-metallic and contains no chlorides. With a special blend of shrinkage-reducing and plasticizing/water-reducing agents, SikaGrout®-300 PT MX compensates for shrinkage in both the plastic and hardened states.

  • Sand-free, allowing for filling and repairing of voids within ducts of post-tensioned structures
  • Does not contain aluminium powder or any components which generate hydrogen gas, carbon dioxide or oxygen
  • Silica fume enhanced for low permeability
 
  • For additional protection, substitute 74 mL of mixing water with 74 mL of Sika® Ferrogard®-901 for each 22.68 kg bag of SikaGrout®-300 PT MX
  • Easy to use, just add clean potable 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 and no build-up on equipment or hoppers
  • Non-corrosive, does not contain chlorides
  • Superior freeze/ thaw resistance

MEZCLADO

For best results use a colloidal mixer. Alternatively, mechanically mix with a high-speed drill (2500 rpm) and Jiffy paddle. Mix for approximately three (3) minutes after the addition of the last bag or until a homogeneous mix is achieved. Continue to agitate material in the holding hopper to achieve optimum flow.

The method of mixing may significantly affect the material properties, particularly flow. At higher temperatures, and/or with higher water amounts, the grout will behave less thixotropically. Therefore, it may be more appropriate to measure the flow using the standard flow cone test (ASTM C939). The expected flux time is between 11 and 30 seconds under normal conditions.

Specific on site testing by the engineer is recommended to ensure that the mixing and placement methods result in the specified requirements.

Start by using 5.44 L (1.44 US gal.) of clean potable water per 22.68 kg (50 lb) bag of material. Add bag of material to mixing vessel. Add additional water as needed- a total maximum of 6.15 L (1.62 US gal.) per 22.68 kg (50 lb) bag - in order to achieve the flow specified. Ambient and material temperature should be as close as possible to +21 °C (70 °F). If higher, use cold water, if colder, use warm water.

APLICACIÓN

Make sure all forming, mixing, placing, and clean-up materials are on hand. The grout should be used within 60 minutes from the start of mixing. The method of pumping the grout must ensure complete filling of the ducts and complete surrounding of the strands or bar. A mock-up should be completed on onsite and inspected by the engineer to ensure that the placement means and methods yield the specified results. When grouting ducts or other critical elements, it is highly recommended that experienced, trained technicians complete the work.

LIMPIEZA DE HERRAMIENTAS

Clean all the tools and application equipment with water immediately after use. Hardened/ cured material can only be mechanically removed.
