Product features of grouting material
.br>Early strength and high strength: resistance to daily pressure can reach above
.br>High self-flowing property: can fill all gaps , to meet the secondary grouting requirements of the equipment.
.br>Micro expansion: ensure close contact between the equipment and the foundation, and no shrinkage after secondary grouting. The bonding strength is high, and the holding force with steel bars is not less than that.
.br>Can be constructed in winter: outdoor construction is allowed at temperatures of ℃.
.br>Strong durability: This product is an inorganic cementing material, and its service life is greater than the service life of the base concrete. After hundreds 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.
Product Usage
.br>Suitable for basic grouting of machine bases, anchor bolts and other equipment.
.br>Reinforcement, repair and reinforcement of building beams, slabs, columns, foundations, floors and roads.
.br>Can be used for anchoring anchor bolts and steel bars and structural reinforcement.
.br>Embedding and fixing construction joints of subway, tunnel, underground and other projects using reverse driving method.
.br>As well as secondary grouting for fixed connections between steel structures (rails, steel frames, steel columns, etc.) and foundations.
Reference usage
The reference usage calculation is based on tons and cubic meters to calculate the actual usage.

Construction steps
.br>Prepare mixing equipment, grouting equipment, formwork and maintenance items, clean the grouting space and wet the concrete surface in advance.
.br>Support the formwork and seal the joints of the formwork with cement (sand) slurry and plastic tape to ensure no water or slurry leakage.
.br>Add water according to the weight of the grouting material and stir (mechanical stirring for 1 minute, manual stirring for more than 10 minutes)
.br>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.
.br>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.
.br>The operating temperature is ℃ to ℃. It is strictly prohibited to mix any additives or external additives into the grouting material.
