Runway special road repair mortar

Runway special road repair mortar [roads, airport runways special road repair mortar] characteristic polymer repair mortar is a polymer material having both adhesion, and durability with a new concrete repair mortar inorganic materials; high compressive strength , rapid curing, good adhesion properties; good water retention properties and crack resistance, high alkali resistance, UV; easy to operate, can damp grass construction, health and environmental protection. Construction steps to make simple, convenient, durable and concrete synchronization, shorten the construction period, to ensure the economy.

[Roads, airport runways special road repair mortar] The main purpose of the product is mainly applied to hollow concrete structures, cellular, damaged, flaking, repair surface damage portion of the exposed tendons, to restore the good performance of concrete structures. But also as a carbon fiber reinforced screeds, masonry mortars and high performance building (structure) building materials suitable protection strand reinforced leveling plaster mortar. The product is due to add a variety of polymer modifiers, powder and crack fibers. So it has good workability, adhesion, impermeability, spalling resistance, freeze-thaw resistance, anti-carbonation, crack resistance, reinforced rust resistance and has high strength and other properties. [Runway special road repair mortar] 1, to facilitate construction: good Workability performance. Construction without vibration, mixing with water in the field can be used; 2, early strength, high strength: one day compressive strength of up to 20Mpa, to maximize speed up the progress of the project; 3, strong impermeability: a good impermeability performance, 1.7Mpa pressure water impermeability impermeable, in line with P16 impermeability of concrete requirements; 4, good adhesion properties: such as using concrete interface treatment agent, and the new and old concrete bonding strength greater than 1.8Mpa, to ensure maximum high-strength concrete repair mortar and repair close adhesion between the grassroots; 5, can be winter construction: polymer repair mortar allows the ambient temperature is above -5 ℃, were window dressing concrete structure and repair outdoor horizontal top surface of the construction; 6, durability: strength after 50 freeze-thaw cycles without significant changes in strength increases 30 days immersed in the oil. [Roads, airport runways special road repair mortar construction method] 1, the primary requirements and treatment: the phenomenon of primary surface should be smooth, rough, clean, no oil, no floating dust, there should be from the sand, hollowing, cracks. Construction of high-pressure water rinse before application and keep moist state, but may not have water. When the interfacial adhesion can be pre-brushing interface treatment agent. 2, material preparation: powder: water mass ratio of 100: 13 Weigh place. The actual amount of 90% of the water into the powder Stir, then the remaining 10% of the water gets poured and stirred no lumps, with a good slurry should guarantee used within 0.5-1 hours. 3, Construction: in wet concrete to grass surface evenly brushing interface treatment agent (A: B = 3: 1), polymer repair mortar a construction area should not be too large, should be staggered slitting block construction, each area not more than 10 square meters, construction staggered intervals of not less than 24 hours. Layered construction, the left seam position should be staggered with each other. 4, polymer repair mortar paving after pressure immediately after wiping and once disappearing, should not be repeated wiping pressure. In case of air bubbles should be punctured pressing, the surface should be dense. Surface layer thickness of the top surface of the facade or greater than 10mm should be layered construction. Plastering thickness of each layer is preferably 5-10M, construction can be carried out pending before the lower layer to touch upon.
