The main products are high-strength non-shrink grouting material series,
, epoxy grouting material, epoxy repair mortar,
bearing grouting material ,
High-strength emergency repair materials, high-strength polymer mortar, high-performance self-leveling
Mortar (colorful high-strength wear-resistant materials, steel-gluing glue, reinforcement-planting glue,
Steel-wrapped pouring glue,
Grouting glue, carbon adhesive, dry hanging glue interface treatment agent, prestressed pipe grouting agent, wear-resistant floor hardener, etc., and product masterbatch
Professional grouting material manufacturer (mainly Used in road and bridge repairs,
high-speed trains, expressways, water conservancy and hydropower, power plants, old building renovation
reinforcement, large machinery base materials, industrial floors and wear-resistant series
etc. ( Strictly implement the latest national standards and can take samples for testing
!)
Product features of high-strength non-shrink grouting material
, self-flowing fluidity is greater than or equal to, and can spread evenly and freely after pouring Flow., self-tightening, has good fluidity
, does not bleed, does not segregate, does not require vibration, and can rely on its own weight
to fill the grouting range., early high strength, early strength, high strength< br/> , strength, strength., micro
The expansion grouting material adopts composite expansion technology, which has both pre-hardening
expansion and post-hardening expansion, which can prevent the grouting material from shrinking
And water loss shrinkage to prevent cracking, hollowing and other phenomena after pouring
And the reduction of the effective bearing surface. The durability belongs to inorganic mixture
, corrosion resistance and aging resistance. Domestic relevant research shows that There is no significant change in strength in the fatigue test and freeze-thaw environment test. After being soaked in machine oil for several days, the strength is significantly improved. Environmentally friendly, non-toxic, harmless, and non-corrosive to steel bars. No pollution to water quality and the surrounding environment
. Winter construction is allowed and outdoor construction is allowed at ℃ temperature
.
Grout material
High-strength non-shrink grout material product uses
Primary grouting and secondary grouting of equipment foundations that require high-precision installation. Burying of steel bars and anchoring of construction and geotechnical engineering. Building reinforcement and renovation projects, beam-column joints, deformation Joints,
Construction joint pouring. Used in emergency repair construction of roads, bridges, tunnels, airports and other projects.
Anchor construction of railway sleepers.
Column wet-clad steel reinforcement is used for pouring angle steel and column gaps. Joints.
Reference dosage of high-strength non-shrink grouting material
Calculate the actual usage
based on the reference dosage calculation. It is precisely because the strength of grouting material is high, far exceeding the energy of cement
Reached strength, and changed the shrinkage characteristics of cement during solidification
, so it is called high-strength non-shrink grouting material!! There are different
grouting materials, such as, etc., these are based on Different buildings
are determined by the standards of the research institute, which does not mean 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 according to the weight of the grouting material and stir (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 covered immediately with plastic film and covered with straw curtains or quilts for a moist and humid curing day.
The operating temperature is ℃ to ℃. It is strictly prohibited to add any additives or external additives to the grouting material.
The unit dosage is about/injection. The national standard for grouting materials is the
regulatory document "Technical Specifications for the Application of Cement-based Grouting Materials" Compressive Strength "Cement Mortar Strength Test
Method" The expansion rate is in accordance with the "Technical Specifications for Application of Concrete Admixtures".
