!)
Features of high-strength non-shrink grouting materials
, self-flowing fluidity is greater than or equal to, it can diffuse evenly and flow freely after infusion. , self-tightening has good fluidity
, no bleeding, no segregation, no need Vibration can rely on its own weight
to fill the grouting range., early high strength, early strength, high strength
, strength, strength., micro
The expansion grouting material adopts composite expansion technology, which has both It expands before hardening
and also expands after hardening, which can prevent the grouting material from shrinking
and losing water, preventing cracking, hollowing and other phenomena after pouring
and the effective bearing surface. Reduced. The durability belongs to inorganic mixture
and is resistant to corrosion and aging. Domestic relevant research shows that there is no significant change in strength after 10,000 fatigue tests and freeze-thaw environment tests. On the machine
The strength is significantly improved after being immersed in oil for a few days. It is environmentally friendly, non-toxic, harmless, has no corrosion to steel bars, and has no pollution to water quality and the surrounding environment. It can be constructed in winter and is allowed to be carried out outdoors at temperatures of ℃
br/> Engineering.
Grouting material
High-strength non-shrinkage grouting material product use
Primary grouting and secondary grouting for equipment foundations that require high-precision installation. Steel bar planting and Anchor anchoring in construction and geotechnical engineering
Construction reinforcement and renovation projects, pouring of beam-column joints, deformation joints,
construction joints. Emergency repairs of roads, bridges, tunnels, airports and other projects
Construction use. Anchorage 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
Reference dosage calculation is based on, calculation Actual usage
It is precisely because the strength of the grouting material is high, far exceeding the strength that cement can
achieve, and it changes the shrinkage characteristics of cement during solidification
so it is called high-strength non-toxic grouting material. Shrink grouting materials!! There are different
models of grouting materials, such as, etc. These are determined according to the standards of different construction
research institutes and do 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 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".
