High-performance Non-Shrink Cement-based

Description Specifications Scope of Application FAQ Download

Description

The cementitious grout is primarily composed of high-strength aggregates, cement or specialized cement, supplemented with additives such as high-flow, micro-expansion, anti-segregation, etc. It is a homogeneous inorganic powder material mixed uniformly through mixing equipment. At the construction site, a certain amount of water is added, mixed evenly, and then injected into the reinforcement area to form a high-strength connection structure.

APPLICATION PROCEDURE

· Clean the surface of the foundation, ensuring no debris such as gravel or dust. Before grouting, the foundation surface should be kept moist, without standing water.

· On-site, determine the water-cement ratio based on the recommended ratio. Water temperature between 5-40°C is suitable, and mechanical or manual mixing can be used. Mechanical mixing should be done for 1-2 minutes. For manual mixing, first add 2/3 of the water and mix for 3 minutes, then add the remaining water and continue mixing until uniform.

· The grout should be poured from one side, not from all sides simultaneously. Grouting should be continuous without interruption, and efforts should be made to shorten the grouting time.

· After grouting is completed, any excess material that needs to be removed should be handled before the grout sets.

· After construction, immediately cover with plastic film and add grass curtains or blankets for moisture retention and curing.

FEATURES AND BENEFITS

· Early strength, high strength:

Compressive strength（40）：1-3 days≥30 MPa, 28 days ≥45 MPa.

Compressive strength（60）：1-3 days≥40 MPa, 28 days ≥60 MPa.

Compressive strength（80）：1-3 days≥60 MPa, 28 days ≥80 MPa.

· High fluidity: Can fill all gaps in equipment foundations without vibration, meeting connection structure requirements.

· High stability: No shrinkage cracks or other defects after formation.

· Micro-expansion: Ensures tight contact between equipment and foundation after grouting.

· Strong durability: Belongs to inorganic bonding material, with a service life longer than that of basic concrete. Withstands hundreds of fatigue test and shows no significant changes in strength after 50 freeze-thaw cycles. Strength significantly increases after soaking in engine oil for 30 days.

Scope of Application

· Secondary grouting for equipment foundations.

· Reinforcement and repair of concrete structures.

· Anchoring of foundation bolts and column base plates.

· Anchoring of reverse construction joints in projects such as subways, tunnels, and underground structures.

· Secondary grouting for fixing connections between steel structures (such as steel rails, frames, and columns) and foundations.
