Teknogrout Repair High Early Strength Repair Mortar

Product description
It is a cement-based, single-component, non-shrinking, very high strength, flowing type concrete especially developed for rapid concrete pouring.

Usage areas
• Ano castings in field concretes,
• Machine rails and foundations,
• Cold conditions and cold storage rooms,
• It is used on runways and aprons that need to be opened to fast traffic.
• In the repair of concrete floors exposed to vehicle and pedestrian traffic,
• It is used on the basis of wind turbines.

Features and Advantages
• It has high hardness and wear resistance.
• Provides very good reinforcement protection and carbonation resistance.
• Since it does not shrink (shrinkage), its usage area is wide.
• It can be applied in thicknesses from 10 mm to 400 mm.
• It does not decompose and does not vomit water.
• It works monolithically with old concrete as it has very high adherence.
• It provides ease of application thanks to its fluid feature.
• Excellent adhesion and excellent durability.
• As high application thickness as possible with the addition of appropriate sized aggregate.
• It gains strength even at very low temperatures, minimum (+)2 °C
• It is resistant to freezing and thawing.

Application Instructions
Surface Preparation: Surfaces must be clean, smooth, solid, free from all kinds of dust, oil, dirt, rust, mold oil, detergent, etc. Repair corners should be cut vertically with a minimum depth of 10 mm. In severely damaged rebars or in cases where rebar sections are below the required safety level, it is necessary to replace the rebars for structural reasons. When additional reinforcement is applied, the reinforcement should be at least 2 cm.
Make sure it is covered in thickness. Surface ice must be completely melted before TEKNOGROUT REPAIR is applied. Although TEKNOGROUT REPAIR can be applied at ambient temperatures as low as (+)2°C, the application surface temperature must be higher than (+)2°C and at most (+)35°C. Absorbent surfaces should be pre-wetted, but water puddles and drops should not remain.

Mixing: Approximately 3.0 lt of clean, clear water is poured into a clean container that is free of any substance preventing adhesion. TEKNOGROUT REPAIR in 25 kg bag is poured into the container filled with water. It is mixed with a low-speed mixer until a homogeneous mixture without lumps is obtained. Mixing time is minimum 3 minutes. should be. The mortar obtained at the end of the process is quickly replaced. After the material has reacted, it should not be mixed by adding water again.

The prepared mixture should be placed in its place within 2.5 minutes, depending on the air temperature and the amount of water. TEKNOGROUT REPAIR should be poured from one side to fill the bottom of the cavities that are surrounded and covered on four sides. Thus, it prevents the formation of gaps by throwing the air out. It can be pushed from one side with a long piece of iron during casting to accelerate the flow. The casting thickness should be between 10 – 400 mm as the layer thickness at a time. It is recommended to make a preliminary trial if it is to be used for filling small diameter anchors in the form of cylinders. In applications thicker than 400 mm, 30% of the material can be added with clean gravel no.2.

Addition of gravel is done in two ways;
• Gravel is added into the mortar. This process is continued until a homogeneous mixture is obtained.
• Gravel is poured or laid on the floor where the application will be made. Then, the mixture is poured onto the prepared TEKNOGROUT REPAIR. The self-leveling mortar also enables us to obtain a high-strength concrete by wrapping all around the crushed stone.

Application Notes / Limitations
• Equipment should be cleaned with water immediately after the application, before it hardens. After the product hardens, it should be cleaned by mechanical methods.
• Reaction times in cement based products are affected by ambient and ground temperatures. Reaction times are shortened in hot environments and longer in cold environments.
• Hot mixing water should be used in cold environments.
• The prepared mixture should be placed in its place within 5 minutes, depending on the air temperature and the amount of water.
• Do not apply TEKNOGROUT REPAIR if the ambient temperature is expected to drop below (+)2°C during application or within 24 hours.
• During the application of the product, work clothes in accordance with the rules of work and worker health should be worn, and appropriate glasses and masks should be used.
• In hot environments, cold mixing water should be used.
• Do not apply at temperatures below (+)2ºC or above (+)35ºC.
• After the application, it should be protected against adverse weather conditions such as direct sunlight, strong wind, high air temperature (over +35°C), rain and frost. Before TEKNOGROUT REPAIR is fully cured and hardened, hands should be cleaned with water and detergent.
