Non-Shrink Concrete Grout
NB 01 NON-SHRINK CONCRETE GROUT
High-resistant, dilatation-controlling grout, purposed for precise grouting of beams, columns, anchor bolts, foundation frames and plates of heavy machines and equipment. Provides non-shrink repairs and anticorrosive protection with ready-made panels, for potable water tanks and facilities.
Strenghts:
• Non-shrink grout, of perfect fluidity properties and controlled dilatation, providing complete filling of closed areas for excellent grouting and repairs
• High initial and end strength
• Long-time grouting and hardening process after 90 minutes
• Freeze-thaw resistance and resistant to defrosting substances
• Water, oil, and petrol-product resisting properties
• Low water/cement proportion
• Safe in both indoor and outdoor use
PREPARATION
Structure must be hard, well cleaned from dust, greasy spots and impurities. Any unstable particles must be removed by sandblasting, sand-water jets or by mechanical scrapping. The so prepared structure must be lavishly poured (preferably 12 – 24 hours beforehand) using clean water until it is uniformly absorbed, without any water rests on the surface. The component supposed to be grouted must be mounted and fixed. Compacts and non-elastic frameworks must be used. Casing must be sound, firmly fixed and tight to avoid any leakage of the grout.
On 25 kg package is to be mixed with 4.0 liters of water. Into a suitable, smooth-wall container, ¾ of the necessary quantity of pure water is to be poured, and then the dry material must be added in portions and stirred by a machine with adequate attachment until a homogeneous mixture is obtained. Then add the rest portion of water and go on stirring until the solution acquires the proper body. The solution must remain for 3-4 min. and then, after restirring, it will be ready for application.
RECOMMENDATION
Use the entire contents of the package when preparing the mixture. Do not additionally wet the plaster during its processing! It is not recommended to add other materials to the finished solution. Strictly follow the specified amount of water!

Laying
For better organization of laying, it is desirable to work two plasterers in a team. The first plasterer applies the solution manually with a trowel up to 30 minutes after its preparation. As soon as 1 to 1.5 m² have already been laid, the second smoothes and scratches depending on the desired structure by horizontal, vertical or circular movements (rubbing) with a plastic squeegee. The first plaster should not exceed the second by more than 1.5 m².
Laying should be done on a dry base and at a temperature of 5ºС to 25ºС. Avoid work in direct and strong sunlight on facades and work time 1-2 hours after laying.
