Eight characteristics of slurry
Early strength, high strength: daily compressive strength of 3- or above.
Anti-segregation performance: High-strength non-shrinkage grouting material overcomes the segregation phenomenon caused by too much water added during on-site use.
, Green and environmentally friendly: It does not contain benzene, halogenated hydrocarbons, formaldehyde, heavy metals and other ingredients. It is non-toxic, odorless, pollution-free, non-flammable and non-explosive, and can be transported as general cargo.
Micro expansion: ensure close contact between the equipment and the foundation, and no shrinkage after secondary grouting.
. High self-flowing property: can fill all gaps and meet the requirements of secondary grouting of equipment
. Can be constructed in winter: outdoor construction is allowed at -℃ temperature.
Strong durability: After millions of fatigue tests and freeze-thaw cycles, the strength has no significant change. The strength is significantly improved after soaking in engine oil for 3 days.
Anti-cracking ability: Cracks occur during on-site use due to factors such as uncertainty in the amount of water added, uncertainty in ambient temperature, and limitations in maintenance conditions.
Purpose of grouting material
Secondary grouting of equipment foundation: suitable for secondary grouting of machine bases, anchor bolts, etc., as well as steel structures (rails, steel frames, steel columns, etc.) fixedly connected to the foundation.
, Anchor bolts and buried steel bars:
. Reinforcement of building bridges, slab and column foundations, floors and roads.
.Can carry out anchor bolts, bolts and steel bars and structural reinforcement.
3. Embedding and fixing construction joints of subways, tunnels, underground and other projects using reverse driving method.
Reinforcement and repair of concrete structures:
Use high-strength non-shrinkage grouting materials to strengthen the cross-sections of concrete beams, slabs, bolts and other components.
.Use high-strength non-shrinkage grouting material to repair concrete holes.
3. Use high-strength non-shrinkage grouting material to repair concrete pavement.
, post-tensioned concrete structure pipe grouting and anchor sealing
Grouting preparation
, grouting equipment, vacuum equipment, grouting pump pressure: .~., vacuum pump vacuum pressure:
/>, use drum phoenix or according to the approved regulations to clean the pipes, and clean up the water, ice and debris in the irrigation pipes.
Check the air outlet of the pipe. If there is any condensation, select a representative pipe for the grouting test.
Grouting operation
Grouting must start from the lowest point or from the lowest steel strand, and grout continuously at a constant speed. Until the grouting is full, the grouting speed should be appropriately slowed down in the corrugated pipe.
After the grouting is completed, the grout should be prevented from losing from the pipeline.
Anchor sealing
When the grout hardens, all openings, grouting pipes and air holes must be tightly sealed to prevent the intrusion of water and harmful substances
For anchors that need to be sealed, After the pipe grouting is completed, first rinse the area around the anchor and roughen the concrete at the beam end, then set up a steel mesh, install an anchor cover outside the anchor head, seal the anchor head with grouting material, and finally grout the anchor. The material is coated with a waterproof coating.
Note: Compressive strength is according to: "Cement Mortar Strength Test Method" and expansion rate is according to: "Technical Specifications for Application of Concrete Admixtures".
When the grouting layer thickness is 3, choose or 3. When the grouting layer thickness is 3, choose 3 or type. For quick repair of pavement, choose type.
Preparation of grouting material:
When mixing the grouting material, the amount of water added should be according to the recommended amount of water on the product certificate provided with the product, and it can be used after stirring evenly. For anchor bolts and buried steel bars, water consumption can be appropriately reduced based on the actual conditions of the project. The mixing water should be drinking water, and other water sources should comply with the current "Concrete Mixing Water Standard".
, The grouting material can be mixed by mechanical stirring or manual stirring. It is recommended to use mechanical stirring method, and the stirring time is generally - minutes (hand electric drill type mixer is strictly prohibited). When using manual mixing, you should first add /3 of the water and mix for 1 minute, then add the remaining water and mix until uniform
. The mixing location should be as close as possible to the grouting material construction site, and the distance should not be too long.
The amount of stirring each time should be determined according to the amount used to ensure that the materials are used up within minutes.
During winter construction, grouting materials and mixing water should comply with the relevant provisions of the current "Code for Construction and Acceptance of Reinforced Concrete Projects" (B).
When used on site, it is strictly prohibited to mix any additives or external additives into the grouting material.
Reference dosage:
The reference dosage calculation is based on .~.tons/cubic meter to calculate the actual usage.
