>[Technical innovation points]
Solved the crack control problem in ultra-thick and large-volume grouting construction
Solved the ultra-thick and large-volume grouting construction Problems of segregation, bleeding, settlement and hollowing in thin and ultra-large volume grouting construction
Expansion rate control issues of materials selected according to the area and thickness of different structural parts
Ensure that the lower surface of the secondary grouting equipment bottom plate is bubble-free and effective The load-bearing area can be used
Used for early-strength and fast-hardening construction problems with hourly strength during emergency repairs
Used for small gap grouting or grouting, and metallurgical blast furnace foundation slag channel walls and slag flushing ditches etc., technical issues with high temperature resistance of heat-resistant components
Fluidity, compactness, strength, expansion rate, durability, effective bearing area, quality control issues
Improving measures for mixing grouting maintenance technology and methods during construction, especially construction technical issues in winter .
【Main technical performance and technical indicators and parameters】
Early strength and high strength, the maximum strength in one day can reach above, and the equipment can be operated one day after installation.
The self-flowing state can be self-leveling by just adding water and stirring on site, and can fill all the gaps without vibrating or tamping
The micro-expansion expansion value has a short stability period, ensuring that the grouting material is in close contact with the equipment floor and foundation. Shrink
The effective bearing area ensures that the contact area between the grouting material and the oversized steel plate of the steel column foot plate of the equipment bottom plate is above.
Durability: 10,000 times fatigue test, 10,000 times freeze-thaw cycle test, no significant change in strength
Heat resistance, long-term use in high temperature environment below blast furnace foundation slag channel wall, slag flushing ditch and other parts
Resistant to oil penetration. After being immersed in engine oil, its strength is higher than before being immersed in oil.
The initial setting and final setting time of the constructable grouting material can meet the construction requirements. Both mechanical and manual mixing can be used for construction. High-level gravity machinery can be used. Various pouring methods such as pumping and high-pressure grouting ensure that the grouting material will not segregate, bleed, or settle after pouring.
[Scope of application]
It is used in large-scale equipment installation projects when the bolts in the reserved bolt holes of the reinforced concrete foundation are anchored in one grouting construction pouring, that is, the anchor bolts in the reserved bolt holes of the bellows.
It is used in secondary grouting construction for filling the cushion between the equipment bottom plate and the foundation in large equipment installation projects.
The grouting construction of the heat-resistant cushion under the fully enclosed condition of the large blast furnace floor is the grouting construction required for self-flowing, vibration-free and self-compacting in heat-resistant environments such as slag tunnel walls, slag flushing ditches and pools.
Grouting construction of the filling layer between the rigid concrete column footings of large steel structure column footings and the foundation concrete foundation.
Grouting construction of reinforced concrete structural beams, slabs, columns, walls and other reinforcement and reconstruction projects with enlarged cross-sections for seismic reinforcement.
Grouting filling construction of railway track crane beams, etc., anchoring of steel bars and building anchors, and anchoring construction of railway sleepers.
The gap grouting gap width of concrete structural brick structure bonded steel or bonded steel plate reinforcement project.
[Construction Precautions]
Engineering and technical personnel should carefully read the "Product Instructions" and "Grouting Material Usage Instructions". Be familiar with the applicable scope of product performance and construction operation methods. When using the grouting material, you only need to add water and stir it, and no other materials are allowed.
During construction, refer to the relevant regulations in the "Construction and Acceptance Specifications for Concrete Structure Engineering" B and the "Technical Specifications for the Application of Cement-based Grouting Materials".
The recommended water consumption on the manufacturer's "Product Certificate" can be adjusted appropriately. The construction unit should determine the actual water consumption based on the on-site construction environment and conditions and after technical personnel conduct trial preparation in the laboratory.
Note the recommended water consumption/grouting material can be adjusted according to the characteristics of the project structure
