I. Product Advantages
1. Non-toxic, odorless, and free from contamination to groundwater and the environment, it is an environmentally friendly grouting material.
2. No shrinkage during slurry curing; high stone strength, excellent durability, non-aging, and good anti-seepage performance.
3. The slurry has good fluidity, with a specific surface area of over 800 m²/kg and an average particle size below 5 μm, thus ensuring high stability and injectability.
4. Slurry solidification time: adjustable according to engineering requirements.
5. The slurry construction process is simple, easy to operate, and suitable for large-scale use.
II. Application Scope
Grouting of dam body and foundation cracks in hydraulic engineering projects.
2. Injected underground waterproof curtain, intercepts water sources of infiltration, and achieves overall anti-seepage and leak sealing.
3. Reinforce and enhance the mechanical strength of soft soil and rock, repair concrete structures, and restore their integrity.
4. Correct cracking and tilting in dams and high-rise buildings caused by uneven settlement due to unstable strata.
5. Grouting reinforcement for ground subsidence beneath highways, bridges, airport runways, etc.
6. Pre-treatment for excavation of various underground structures, as well as engineering services such as hole protection and wall stabilization during complex stratum drilling, and stopping water gushing and leakage.
7. Sand stabilization in complex stratified layers and consolidation of silt soil layers.
III. Technical Specifications
1. The physical properties of the casting material (measured at 21℃) allow for the production of ultra-fine cement grouting material according to special customer requirements.
2. The strength ratio of the slurry under different water-cement ratios is as follows: Just like cement, the fluidity and permeability of the grouting material increase with the increase of the water-cement ratio. However, the setting time extends and the strength decreases with the increase of the water-cement ratio. Therefore, under the premise of meeting the construction requirements, the water-cement ratio should be minimized as much as possible.
Four: Packaging and Storage
Packaged in plastic woven bags, net weight 25kg per bag, shelf life 6 months.
Store in a dry, well-ventilated room; keep bags sealed to prevent moisture and freezing.
V. Instructions for Use
1. For different gap sizes, soil geological conditions, grouting foundation requirements, and strength criteria, determine the appropriate water-cement ratio (typically ranging from 0.5 to 4.0 for grouting materials). Mix using an electric mixer until uniform, then pour the slurry into the grouting drum.
2. Align and securely connect the nozzle of the grouting machine to the pre-fixed grouting nozzle on the foundation. Connect the power supply to the grouting machine, open the valve to start grouting. Control the grouting pressure within a certain range (usually between 0.1-0.5 MPa). The required grouting pressure varies depending on the foundation conditions and the water-cement ratio. Excessive grouting pressure may cause cracking and uneven penetration. Insufficient pressure may not penetrate into small spaces.
3. Seal the grouting holes after the grouting is completed.
4. When the grouting area is large, segmented grouting can be employed.
Section 6: Cautionary Notes
1. Materials must be mixed with a high-speed mixer (1500 rpm) for at least 5 minutes. During the casting process, a low-speed mixer should also be used to prevent settlement.

2. Ultra-fine cement grouting material is a grouting material based on cement. During use, wear gloves, protective eyewear, and a dust mask, and wear work clothes to prevent eye and skin burns. If it accidentally splashes into your eyes, rinse with plenty of water immediately and consult a doctor; if accidentally ingested, drink plenty of water immediately and seek medical advice.
