High-strength non-shrinkage grouting material
High-strength non-shrinkage grouting material
The grouting material is formulated with high-strength materials as aggregates, cement as binding agent, and supplemented by high fluidity, micro-expansion, anti-segregation and other substances. become. It can be used after adding a certain amount of water at the construction site and stirring evenly.
It has the characteristics of good self-flowing properties, rapid hardening, early strength, high strength, no shrinkage, micro-expansion, non-toxic, harmless, no aging, no pollution to water quality and surrounding environment, good self-tightness, and anti-rust. In terms of construction, it has the advantages of reliable quality, reduced cost, shortened construction period and easy use. Fundamentally change the stress situation of the equipment base so that it can evenly bear the entire load of the equipment, thus meeting the installation requirements of various mechanical and electrical equipment (heavy equipment high-precision grinders). It is an ideal grouting material in the era of padless installation.
★Features of grouting materials
Strong and high-strength compressive strength can reach above.
The high fluidity can fill all the gaps and meet the requirements of secondary grouting of the equipment.
The expansion property ensures close contact between the equipment and the foundation, and there is no shrinkage after secondary grouting. The bonding strength is high, and the holding force with steel bars is not less than that.
Winter construction allows outdoor construction at temperatures of ℃.
Strong durability: This product is an inorganic cementing material, and its service life is greater than that of the base concrete. After millions of fatigue tests, there is no significant change in the strength of the freeze-thaw cycle test. The strength is significantly improved after soaking in engine oil.
★Use of grouting material products
Used for basic grouting of machine bases, anchor bolts and other equipment.
Reinforcement, emergency repair and reinforcement of building beams, slabs, columns, foundations, floors and roads.
Carry out anchor bolts and steel bars and structural reinforcement.
Embedding and fixing construction joints using reverse driving method in railway, tunnel, underground and other projects.
And secondary grouting for fixed connections between steel structures (rails, steel frames, steel columns, etc.) and foundations.
★Reference dosage of grouting material
The reference dosage is calculated on the basis of / cubic meter to calculate the actual usage.

< br/> ★Grouting material construction steps
Prepare mixing machines, grouting equipment, templates and maintenance items, clean the grouting space and wet the concrete surface in advance.
Set up the formwork and seal the joints of the formwork with cement (sand) slurry and plastic tape to ensure no water or slurry leakage.
Add the amount of water according to the weight of the grouting material, add water and stir (mechanical stirring for 1 minute, manual stirring for more than 10 minutes)
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 properly vibrated or lightly tapped.
After the work is completed, the curing agent should be sprayed immediately or covered with plastic film and covered with straw curtains or quilts for a moist curing day.
The operating temperature is ℃ to ℃. It is strictly prohibited to mix any additives or external additives into the grouting material.
★ Packaging, storage and transportation of grouting material
The grouting material is packed in bags and stored in a ventilated and dry place away from direct sunlight.
The shelf life is one month. If it exceeds the shelf life, it must be re-inspected before it can be used.
Our company specializes in the production of high-strength non-shrink grouting materials with quality assurance. Welcome to consult and negotiate
