High-strength repair mortar
>
This product is formulated with a variety of polymer modifiers, rubber powder and anti-crack fibers. It has good construction ease and bonding properties. properties, impermeability, crack resistance, peeling resistance, freeze-thaw resistance and high strength, etc.
Scope of application
Repair of damaged components, beams, slabs, columns, stairs and other parts in concrete structures.
, Buildings (structures) use plastering, leveling and protection mortar reinforced with high-strength stainless steel stranded wire mesh
, Repair of damaged concrete parts in roads and bridges.
Repair and emergency repair of damaged parts of airport runways and highway lane ramps.
, repair and emergency repair of damaged parts of concrete floors in industrial plants.
Construction features
Convenient construction and good construction and ease of performance. No vibration is required during construction, just add water and stir on site before use.
The compressive strength of early-strength and high-strength days can be reached, which can speed up the project progress to the maximum extent.
, Strong impermeability and good impermeability. The seepage water is impermeable and meets the requirements for the impermeability of concrete.
. Good bonding performance. Using concrete interface treatment agent, the bonding strength with new and old concrete is greater than that, which can ensure the tight bonding between high-strength repair mortar and repair base layer to the greatest extent.
High-strength repair mortar that can be constructed in winter allows repair of facades, horizontal planes, and top surfaces of concrete structures and outdoor construction when the ambient temperature is above ℃.
. Durability: There is no significant change in strength after freeze-thaw cycles. However, the strength increases after being soaked in engine oil for several days.

Construction steps and requirements
, prepare necessary tools and maintenance items
, determine the repair area, initial stage The scope of repair treatment should be expanded outward than the actual damage range, and the vertical edges of the concrete repair area should be cut or chiseled out to an initial depth to prevent the edges of the repair area from becoming flaked.
Clean the floating dust and oil on the surface of the concrete base in the repair area, and remove the loose parts.
Clean the rust and debris on the surface of the exposed steel bars in the repair area.
. Chill the concrete base in the cleaned repair area or use a concrete interface treatment agent for interface treatment.
Use an air pump or water to clean the surface of the concrete base in the treated repair area. No open water should remain in the next process
. Mix the high-strength repair mortar with the recommended water amount (weight ratio). Mechanical stirring should be done for 10 minutes, manual stirring should be done for 10 minutes to ensure uniform mixing.
The mixed high-strength repair mortar can be plastered. The thickness of plastering should not be exceeded at one time. If the plastering layer is thick, the construction method of layered and multiple plastering should be used.
Since the high-strength repair mortar contains a variety of molecular polymer-modified exudates and rubber powder, the mixed high-strength repair mortar is more viscous, and the spatula should be kept smooth when plastering.
For surfaces that require calendering, the plaster should be mixed slightly thinly and the time should be mastered to utilize calendering.
It is strictly prohibited to mix any additives or external additives into high-strength repair mortar. The operating temperature is ℃℃
Maintenance
Hours after completion of construction work in summer, timely watering and spraying of curing agent or covering with wet straw bags should be carried out for maintenance, and the surface should be kept moist for days.
After the winter construction work is completed, the thin plastic moldings should be covered immediately and covered with quilts for thermal insulation and maintenance.
Packaging and storage
Packaging specifications/bag.
Store in a ventilated and dry place and prevent direct sunlight. The shelf life is months. It should be re-inspected after the shelf life is exceeded, and it can be used only after passing the test.
