!)
High strength Features of the non-shrink grouting material
: Self-flowing fluidity is greater than or equal to 3. It can spread evenly and flow freely after pouring. It is self-tight and has good fluidity
and does not leak. Water, no segregation, no need for vibration, can rely on its own weight
to fill the grouting range. Early high strength, early strength, strength
3,3 strength, strength., micro
expansion grouting The material adopts composite expansion technology, which has both pre-hardening expansion
and post-hardening expansion, which can prevent the grouting material from settling and shrinking due to water loss, and prevent cracking, hollowing and other phenomena after filling.
And the effective bearing surface is reduced. The durability belongs to inorganic mixture
, corrosion resistance and aging resistance. Domestic relevant research shows that: 10,000 times fatigue test, 10,000 times freeze-thaw environment test strength There is no obvious change. After being soaked in machine oil for 3 days, the strength is significantly improved. Environmentally friendly, non-toxic, harmless, no corrosion to steel bars, no pollution to water quality and the surrounding environment. , can Winter construction allows outdoor construction at -℃ temperature
.
Grout material
High-strength non-shrink grout material product use
One-time grouting and equipment foundations that require high-precision installation Secondary
grouting. Steel bar embedding and anchor bolt
fastening in construction and geotechnical engineering. Building reinforcement and renovation projects, beam-column joints, deformation joints,
construction joint pouring. Roads, bridges , tunnels, airports and other projects
Used in emergency repair construction. Anchor construction of railway sleepers.
Column wet-clad steel reinforcement is used for pouring angle steel and column gap joints.
Reference dosage of high-strength non-shrink grouting material
The reference dosage calculation is based on .~./3 to calculate the actual
dosage. It is precisely because the strength of the grouting material is high, far exceeding the strength that cement can
achieve, and it has changed The characteristics of cement shrinkage when curing
, so it is called high-strength non-shrink grouting material!! There are different
grouting materials, such as, etc., these are based on different construction
research It is determined by the hospital's standards and does not represent the quality of the product. Specific
usage needs to be tested.
Construction steps of high-strength non-shrink grouting material
Prepare mixing machines, grouting equipment, formwork and maintenance items,
Clean the grouting space and wet the concrete surface in advance. , support the formwork and use cement (sand) slurry and plastic tape to seal the joints of the formwork
to ensure no water or slurry leakage. Add water and stir according to the
weight of the grouting material (mechanical stirring for 1 minute, manual stirring for more than 10 minutes), and pour the evenly stirred grouting material into the grouting part from one direction. If necessary, bamboo strips or steel drills can be used to guide the flow, and the template can be vibrated or lightly tapped. . After the construction is completed, it should be immediately covered with plastic film and covered with straw curtains or quilts for 3-days of moist curing.
The operating temperature is -℃ to ℃. It is strictly prohibited to add any additives or external additives to the grouting material.
Unit dosage: about/3 Note: National standards for grouting materials
Regulation documents "Application technology of cement-based grouting materials
Technical specifications" Compressive strength "Cement mortar strength test
Method》The expansion rate is according to the "Technical Specifications for Application of Concrete Admixtures".
