Grout 500 A Grouting Admixture for Cement Mortars and Concrete
Perma Grout - 500 is a fine free flowing grey powder with a wide range of grouting applications, mainly to produce expansive grouting slurries, mortars and concrete. Primary Uses Perma Grout - 500 is an admixture for grouting Cement slurries, grouting mortars and non shrink concrete. Perma Grout - 500 is a free flowing grey powder especially designed for cable duct grouting in post tensioned bridge girders, injection grouting of porous concrete in structural rehabilitation works and in infill mortars in filling and sealing cut outs, recesses and foundation pockets. Functions
- Perma Grout - 500 when admixed with cement imparts an expansion of 6% in cement slurries. This expansion ensures proper contact and good adhesion of the slurries with inner surfaces of the pocket to be grouted.
- Perma Grout - 500 imparts free flowing properties in cement slurries and mortars. This property is extremely essential in any grouting situation.
- Perma Grout - 500 imparts high early and ultimate strengths to grouting slurries, mortars & concrete.
- Perma Grout - 500 improves the quality of grouting material.
- Perma Grout - 500 is free from metallic iron chlorides, sulphates and nitrates.
Direction for use Perma Grout-500 is added to the dry ingredients and mixed well before addition of water.
TYPICAL mixes for various applications are as follows:
Neat Cement Grout

- Aggregates: 200 kgs
- Perma Grout 500: 25 litres
- Yield: 0.056 m3/150 ltr.
Precautions
- All grouting products exhibit the properties when used in restrained conditions. When used in open areas or shallow pockets where depth is less than its width the unrestrained expansion causes surface cracks and results in very low compressive strengths.
- Perma grout - 500 should be used at a dosage of 500 gms or less per 50 kg bag of cement. Higher dosages will led to poor strength and result in setting problems.
- In cable duct grouting the slurry should be pumped at a pressure of 0.3 MPA continuously till completion. The grout should flow at a speed of 5 to 10 meters per minute.
Dosage Strictly Perma Grout - 500 gms per 50 kg bag of cement. Dosage not to be exceeded except under special circumstances or under the guidance of Perma technical staff. Packing 500 gms and 10 kgs sack. Shelf Life One year from the date of manufacture, if stored in cool and dry conditions.
