SikaGrout®-300 PT
HIGH-PERFORMANCE, ZERO-BLEED, SAND-FREE, CEMENTITIOUS GROUT
SikaGrout®-300 PT is a fluid, non-shrink, cementitious grout with a unique, two-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 compensates for shrinkage in both the plastic and the hardened states.
- Sand-free allows filling and repairing of voids
- Does not contain aluminum powder nor any components which generate hydrogen gas, carbon dioxide or oxygen
- Silica fume enhanced for low permeability
- For additional corrosion protection, 75 mL (2.5 fl. oz) of Sika® FerroGard®-901 may be substituted for 75 mL (2.5 fl. oz) of mixing water for each 22.7 kg (50 lb) bag of SikaGrout®-300 PT
- Easy to use; just add water
- Non-metallic; will not stain or rust. Non-corrosive; does not contain chlorides

* Fluid consistency compressive strengths are given as minimum guidelines. Pourable and dry pack consistencies will easily exceed these values. All moulds, mixing tools and powder components were pre-conditioned to the test temperatures. Prepared test specimens were cast and then cured at the indicated test temperatures until the time of testing. Lid should be clamped on mold at all time. Maximum liquid/solids ratio (water + Sikacem® Accelerator/SikaGrout®-300 PT) = 0.27; [6.15 L (13 pints) of liquid per 22.7 kg (50 lb) bag of SikaGrout®-300 PT].

Yield
Approx. 14 L (0.50 ft3) of fluid grout per bag. Use (as described in the mixing procedure below) between 5.45 and 6.15 L (11.5 and 13 pints) of water per 22.7 kg (50 lb) bag in order to achieve the proper flow.
SURFACE PREPARATION
Remove all dirt, oil, grease, and other bond-inhibiting materials by mechanical means. Anchor bolts to be grouted must be de-greased with suitable solvent which will not inhibit grout bonding. Follow solvent manufacturer’s instructions and warnings. Concrete must be sound and roughened to promote mechanical adhesion. Prior to placing, surface should be brought to a saturated, surface-dry (SSD) condition.
MIXING
The whole mixing process (including type of equipment, mixing speed, mixing time, quantity of mixing water, temperatures of the mixing water and the material, ambient temperatures and batch size) will affect the material properties, particularly flow. At higher temperatures and/or with higher water amounts, the grout will behave more non-thixotropically. Site testing at the commencement of the project is recommended to ensure that the mixing and placement methods result in the specified requirements.
For best results use a colloidal mixer similar to ChemGrout CG-600 series or other type of high shear mixer at approximately 1800 rpm. 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 best flow. Depending on batch size it may be necessary to continue mixing for up to six (6) minutes to obtain the desired flow.
Alternately, for small quantities, such as when vacuum grouting voids, mechanically mix with high-speed drill (2500 rpm) and Jiffy paddle for a minimum of six (6) minutes.
Add appropriate quantity of clean water. Add material to mixing vessel. Start by using 5.45 L (11.5 pt) of water per 22.7 kg (50 lb) bag of material. If the minimum quantity of mixing water is not sufficient to obtain a flow meeting specifications, gradually add more mixing water, never exceeding the maximum quantity of 6.15L (13 pt) per 22.7 kg (50 lb) bag. Ambient, water and material temperatures should be as close as possible to +21 °C (70 °F). If higher, use colder water; if colder, use warmer water. Note that it is quite possible to obtain the required flow at the lower end of the water requirements and it is important to start at 5.45 L per bag. Note that excessive water in the mix may cause exudation or bleeding.
Accurate measurement of the quantity of water to be added is important to maintain consistency between batches. If water is to be added via an in-line system, the water metering equipment must be properly and professionally calibrated and checked on a regular basis during the course of the project
CLEANING
In case of spill, wear protective equipment (chemical resistant gloves/goggles/clothing). Ventilate area. In the absence of adequate ventilation, use a properly fitted NIOSH respirator. Confine spill. Vacuum or scoop into an appropriate container. Dispose of in accordance with current applicable local, provincial and federal regulations.
