duragrout® GP – non-shrink, cementitious general purpose grout

• Quickly develops placeable consistency
• Impermeable
• Non-shrink
• Adjust consistency to suit application requirements
• Remains cohesive and does not segregate or bleed

A minimum clearance of 50 mm is required between bed and base. For smaller areas where the flow will not be restricted, a limited minimum thickness of 25 mm is recommended. When grouting anchor bolts, three times the bolt diameter is necessary. Smaller clearances should be grouted with one of the epidermix range of epoxy compounds.

Provision for the escape of entrapped air must always be made. Contact surfaces must be clean, sound, free from dust and shutter release oils. Concrete surfaces must be thoroughly pre-wetted but excess surface water (free water) must be removed prior to placing the grout. Surface and ambient temperatures must be greater than +5 ^oC and rising. Always ensure that the shutters are watertight and sealed to prevent suction of water from the product. Ensure that the grout delivery head is of adequate height in order to accommodate the distance the grout must flow. Always pour from one side thus ensuring that the grout fills the void without entrapping air.

No primer required but in certain Instances where structural bonding is required abe^® epidermix^® 344 should be used.

Ensure that the substrate is thoroughly saturated (SSD) surface saturated dry at least 24 hours prior to placing the grout. This reduces suction by the substrate that would absorb water from the grout and in turn impair the flow properties of the grout.

All water contents apply to 25 kg pockets of duragrout^® GP. Water quantities must be adjusted to match size of mix. Mixes must always use complete pockets, but more than one pocket may be used. Mixing of grout may be carried out in a pan mixer, drum mixer or by using a slow-speed electric drill fitted with a suitable paddle. Using the standard 25 kg pocket of grout, add 3,5 L of clean water to the mixing vessel. While stirring continuously, add the dry powder until the mixture is free from lumps. Then add further water (1 L), continue mixing until a smooth, creamy consistency is obtained. Total mixing time should be approximately three minutes.

The water demand to obtain the desired plastic consistency for duragrout^® GP must be reduced as required.

The minimum depth of grout to qualify for extending with 13 – 16 mm clean dust free stone is 100 mm. The estimated water demand for a pourable (flow table spread 270 – 300 mm – with no drop) consistency is 4.5 litre per 25 kg bag, or less depending upon consistency required, is added to the mixer first followed by the dry grout.

After mixing for 2-3 minutes, 14 litres of 13 – 16 mm clean stone should be added, mix for an additional 2 minutes to ensure good dispersion of the aggregate is obtained. After extending the grout, a lessening of flow of the mixed grout will be noted. Under no circumstance may the water demand exceed 4.5 litres/25 kg of grout excluding stone, as this would impair the quality of the matrix and the product, possibly bleed, shrink, and not perform to
our specification.

This extended grout may require agitation by means of strapping to aid in placing thereof.

One bag of duragrout^® GP will yield approximately 0.0145 m³ (14.5 L) of grout (4.5 litre water demand). Yield as per extending above 0.0245 m³ (24.5 litres) of grout using 4.5 L water demand (LBD of stone of 1.35).

The mixed grout should be poured into the cavity at one point only to avoid entrapping air. For best results, mixed grout should be poured within 10 minutes of mixing and definitely within 30 minutes. If grout is not placed immediately after mixing, keep the material agitated. Grouting mixture more than 30 minutes old must be discarded. duragrout^® GP can be compacted by gentle rodding or punning.

Do not re-temper the grout, should the consistency drop due to time lapse, then discard the mix and mix a fresh batch of product.

duragrout^® GP should be removed from tools and mixing equipment immediately after use and before material has set with clean water. Cured material can be removed mechanically.

Grout surfaces should be protected from wind or high temperature, which can cause rapid drying. Cover the surface with damp sacks. Do not allow the sacks to dry out; alternatively apply Chryso Cure R or Chryso Cure WB curing compound or as recommended by abe.^® Construction Chemicals.

The grout will be duragrout^® GP , a pre- packed, one-component, non-shrink, precision grout applied in accordance with the recommendations of a.b.e.^® Construction Chemicals, including curing with CHRYSO Cure R or CHRYSO Cure WB.

The grout will be duragrout^® GP, a pre- packed, one-component, non-shrink, precision grout applied in accordance with the recommendations of a.b.e.^® Construction Chemicals, including curing with CHRYSO Cure R or CHRYSO Cure WB.

duragrout^® GP is supplied in 25 kg polyethylene lined paper bags.
NOTE
For precision or other critical high performance grouting requirements of heavy machinery or other applications use
duragrout^® GP.
For other quick setting or chemical resistant grouting applications contact abe.^®Construction Chemicals.

duragrout^® GP has a shelf life of 12 months if kept in a dry store in sealed bags. If stored in high temperature and in high humidity locations the shelf life may be reduced.
