Concrete thin layer protection of concrete repair material no. 1

Thin layer of concrete repair material of protection of concrete 1 1 construction concrete thickness 3 mm can meet the requirements of the special load path of compressive, has the inestimable social benefits and economic benefits. Protect a concrete number specifically for concrete pavement pits, empty drum, peeling, hulling, cracks, exposure and disease timely repair, directly apply it in disease, need to have strong compressive strength and bonding strength, can realize the ultra-thin patch, in the condition of high speed and high voltage driving there will not be broken and peeling phenomenon; All concrete surface diseases are suitable for this material. To protect the concrete practical performance: the number one without complex construction machinery and construction technology requirements, without long time closed transportation, construction can open 3 hours after the traffic; Don't need to disease site excavation, can save a lot of construction costs, cost of raw materials and curing time, effectively delay the spread of the spread of the disease and roads, prolong the service life of road; And with the original color close to the cement concrete pavement after repair, good and beautiful. 1: adhesive performance using the material itself, adhesive ability and the principle of surface energy, repair the surface and the original concrete reaction into a unified whole, forming a high bonding strength, two hours after the construction of bonding strength can reach 1. Parts of adhesive 6 mpa, but with a variety of diseases, basic is not affected by the thickness of adhesive ability, which can realize 1 mm thin repair, in scale, rolling, goes on under the external force and not fall off, such as not disintegrate. 2: durable performance faster performance and high early strength, early and late do not decay, parts for many diseases can be one-time eradication; Material itself has a strong waterproof, corrosion resistance and ultraviolet resistance, the anti-aging ability is more than 5 times of the original cement concrete, no earlier than the original concrete performance attenuation, will not lose by aging adhesive ability and compressive strength. 3: the compressive performance of concrete curing after number one very strong compressive and flexural capacity, two hours of up to 22 mpa compressive strength, post strength rising above the peak compressive strength of 100 mpa, the disease has very good reinforcing and supporting role, repair the thickness 3 mm can meet the requirements of the special load path of compressive, in the condition of high speed and high voltage driving there will not be broken and fall off. Operation method: 1, the surface treatment process to clean up: the drum first, peeling, cracks and other parts of the loose parts of take off, for less than 3 mm, too flat parts and have the part of the oil to processing roughening method with special machine or artificial hair, hair tip of hammer percussion. 2, cleaning: the underside of aggradation and other debris swept clean, wash clean with high pressure water, wash the mud should be out of the operation and to prevent backflow. 3, water embellish: after rinse clean with water, water conservation should be remain in operation for a period of time, the operation fully nourishes, until no longer ooze water ( Construction paint must be kept in operation in the wet state) Basic requirements: 1, usage: repair is 1 mm thick, dosage of about 1 kg per square. 2, water with clean water. 3, construction more than 3 mm thickness is advisable. Construction conditions: 1, the temperature should be above 5 degrees, rain and snow day not construction. 2, construction personnel have a certain cement concrete construction experience of the best. Construction machinery: mixing mortar mixer or manual tool ( Hand electric drill modified) , high pressure water washing equipment, floor cleaning tools, sponge or mop ( Blot excess water use) , stirring barrels of two or more iron, float several. Material allocation: 1, first put the water into container inner protection of concrete one, the material is mixed with water and stirring, water content from 17% to 22% ( Generally good mixing basically is a little liquid, customers can be adjusted according to the disease situation of) 。 Must be fully stir well when stirred, observing without powder and bubbles. 2, evenly stirring should let material static surface without MingShui after 1 minute, stirring once again can be blotted out pour in operation. According to the operation and construction schedule, and each mixing material should be finished as soon as possible, in case of solidification of mixing materials should not exceed half an hour. Construction and timing: to repair the surface fully nourishes, surface wet but no MingShui, if there is a water potholes parts, water with sponge or dry cloth blot before construction, if there is water will destroy the material in water affecting strength; If you have appeared on the surface of a dry phenomenon, with rain sprinkled wet again; The dry humidity of operation to maintain appropriate help adhesive and convenient for construction. Packing and storage: compound kraft paper bags, 50 kg per bag, a cool and dry place 6 months shelf life
