DEFIX GROUT G-1 Non-Shrink Grout – High-Strength Grouting Solution for Machine Foundations, Anchor Bolts, and Concrete Structures

In industrial constructions, factories, bridges, or precast concrete structures, selecting high-quality grouting material plays a crucial role in the stability and longevity of the entire structure. If conventional grout is used, shrinkage after hardening can create gaps, reducing load transfer capacity, loosening anchor bolts, causing machine foundations to vibrate, or decreasing structural strength over time. Therefore, DEFIX GROUT G-1 Non-Shrink Grout has been developed to provide a self-leveling, high-strength, dimensionally stable, and non-shrinking cement-based grouting solution, meeting the stringent requirements of modern civil and industrial projects. The product's technical specifications and application instructions are detailed in DEFIX's technical documentation.

What is DEFIX GROUT G-1?

DEFIX GROUT G-1 is a pre-mixed cement-based grout that only requires the addition of the correct proportion of water for use. The product is self-flowing, self-leveling, and non-shrinking after setting under appropriate curing conditions, effectively transferring loads between structural components and foundations. It is a specialized solution for applications requiring high compressive strength, excellent dimensional stability, and rapid execution.

Unlike manually mixed cement mortar, DEFIX GROUT G-1's composition is controlled at the factory, ensuring consistent quality across different batches, reducing errors in mix proportions, and improving practical construction efficiency.

Applications of DEFIX GROUT G-1 Non-Shrink Grout

DEFIX GROUT G-1 is widely used in many construction and industrial applications, especially in areas requiring high load-bearing capacity and long-term stability.

The product is suitable for grouting industrial machine foundations, rail beds, precast concrete column bases, anchoring bolts, bridge bearings, gaps between components, wall cavities, voids in concrete structures, and high-strength repair areas. These are all areas that demand materials capable of effective load transfer without settling or shrinking after hardening.

Outstanding Advantages of DEFIX GROUT G-1

One of the strengths of DEFIX GROUT G-1 is its self-leveling capability with high fluidity, allowing the material to easily fill small gaps, voids, or deep cavities without extensive vibration. This reduces the risk of air bubbles and increases contact with concrete or metal surfaces.

The product also exhibits good dimensional stability, with no shrinkage after hardening under suitable curing conditions, thereby ensuring effective load transfer between components.

Furthermore, DEFIX GROUT G-1 has high compressive strength, reaching at least 25 MPa after 1 day, 41 MPa after 3 days, 52 MPa after 7 days, and 60 MPa after 28 days, meeting the requirements of many industrial and load-bearing structural applications.

In addition, the product possesses numerous advantages such as:

No segregation during setting.
Good resistance to impact and vibration.
Non-toxic, non-corrosive to metals.
Can be pumped using specialized grout pumps.
Only requires the addition of clean water for immediate use.

Key Technical Specifications

DEFIX GROUT G-1 is packaged as a concrete gray powder in 5 kg and 25 kg bags. Each 25 kg bag, after mixing, yields approximately 13.1 liters of grout, equivalent to about 76 bags for 1 m³ of grout.

Some notable technical specifications include:

Water mixing ratio of approximately 15% by weight, equivalent to 3.75 liters of water per 25 kg bag.
Working time at 30°C is approximately 30 minutes.
Flowability reaches 250–320 mm according to ASTM C230.
Expansion after 24 hours ≥ 0.1%.
No segregation occurs.
Adhesive strength ≥ 0.5 N/mm².
Minimum grouting layer thickness 10 mm.

These specifications help the product meet the technical requirements of many projects from civil to industrial.

DEFIX GROUT G-1 Application Instructions

For optimal results, concrete surfaces must be clean, free of oil, dirt, and contaminants. For metal surfaces, rust and oil must be thoroughly cleaned before application. Water-absorbing surfaces should be saturated with water but without standing water.

When mixing, slowly add the powder to the predetermined amount of water, using a low-speed mixer for at least 3 minutes to achieve a homogeneous mixture. Then, let the mixture rest for about 5 minutes before proceeding with grouting.

During grouting, maintain a continuous flow to prevent air bubbles and ensure the grout completely fills all voids. For large cavities or grouting layers thicker than 60 mm, appropriate aggregates can be added according to technical guidelines to reduce heat generation during hardening.

Important Notes for Use

To ensure construction quality, the application temperature should be between 10°C and 40°C. If applied below 20°C, the setting time and strength development will be slower than normal. After completion, exposed surfaces must be cured for at least 3 days to achieve the desired strength and stability.

As the product is cement-based and alkaline, applicators must wear full protective gear and avoid prolonged direct contact with eyes or skin.
