Other Details

Our organization also offers Non Shrink Cementitious Grout YP –Grout NS2, which is a combination of ultra high strength cement, admixture, well graded fillers & special expanding agent, free from corrosive substances. It is a free flowing, does not shrink and comes in pre packed ready-to-use grout.

Benefits:

Excellent mechanical & flow properties

Non shrink with controlled expansion

High early & ultimate strength

Dense grout resistance to oil & water penetration

No bleeding & segregation

Action:

It compensates shrinkage and does not shrink when it is fully restrained

It should be used to minimize cracking, which is caused by drying of shrinkages

When it is fully controlled by reinforcement or by physical restrain, its expansion creates solidity in mortar

On successive drying of shrinkages, thus, produced causes a tensile stress to develop (which might cause cracking) merely reduces to relieve the expansive strains caused by the initial expansion

The effectiveness of shrinkage compensating capability is reduced if partial restrain is provided

As the restrain improves, it assists in the increase of shrinkage compensation

It can be safely used in direct contact with metals without any corrosion

Directions for use:

Surface treatment:

All surfaces, which will come in contact with mortar, must be clean, sound, & dense

All laitance and any unsound material should be removed from the site

Evenly scrub the surface so that it is slightly textured without any dust & dirt

The surface must be sprinkled with water to dampen the concrete but all the surface water must be wiped out

Mixing:

For pour able consistency add 2.75 lts of water to 25 kg bag & mix it thoroughly

For flow able consistency add 3.25 lts of water to 25 kg bag & mix it thoroughly

water should be added slowly over 1.5 min period & then mix it with the help of mechanical mixer for another 2 mins

In order to get desired results water should be accurately added by + -0.1 lts

Setting Time:

Initial > 30 Min

Final < 600 Min

Flow Table:

Flow > 200 Mm.
