Description wear hardener is a kind of inorganic silicates as the main component, adding a suitable catalyst and additives obtained environmental aqueous liquid. It can penetrate into the concrete, with the concrete in the reactive material crystallized to form insoluble gels, clogging concrete during the molding of a large number of pores are formed, so that the surface of the concrete is more compact, thereby increasing the surface hardness of the concrete, corrosion wear resistance and strength to prevent the surface from dust, prevent water, oil, acid and other substances penetrate corrosion, prevent the occurrence of the base concrete and alkali silica reaction of carbon reactions, protect concrete from corrosion, extending the life of concrete. Surface morphology: light life: more than 20-25 years Features: (1) an inorganic water-based materials, non-toxic environmental protection; (2) sealed concrete capillary; (3) the surface of hardened concrete, reinforced concrete floor of the old and new surface hardness and wear resistance; (4) to improve the strength of the old and new concrete floor; (5) to prevent the concrete spalling Spallation; (6) the dense floor resistant to water, oil, and acid salt and other chemical substances erosion. (7) to prevent mold growth; (8) greatly reduced the permeability of concrete to water; (9) effectively extending the life of concrete; (10) after the application of the new wear-resistant aggregate surface hardening agent can get better gloss ; (11) on the concrete floor of the apparent effect is not adversely affected; (12) for the application of the floor hardener Paint can not affect the performance of the coating; (13) easy to use. Note: ① in the molding surface of concrete and effective use of income and curing can be more significant results; ② the effect of the floor surface using a new concrete better; ③ It is a colorless liquid penetration into the concrete , does not change the color of the concrete can not be used to fill the closed fracture; ④ the longer the reaction time is longer, the better use of time; ⑤ floor cleaning routine cleaning can accelerate the reaction and improve performance. Scope: Concrete hardener is a unique new and used high-strength concrete floor products. For indoor and outdoor concrete floors or walls, to strengthen, hardening, dust and sealing purposes. It can be used: a variety of workshops concrete floor, hardened aggregate floor, parking, bridges, roads, roads, airports, shopping malls and other large warehouse concrete floor. Construction Technology: ① concreting requirements: concrete floor strength design requirements above C25, not less than C20. ② Clean Floors: For new poured concrete (including abrasion resistant hardened ground), using a trowel smooth, compacted, should conserve at least 7 to 14 days (the use of water conservation), polished, clear white base and dust surfaces. For the old concrete floor, remove the impact of the oil penetrate the surface of the material, paint and loose structure, thoroughly clean the floor. ③ For dry old ground, use clean water to fully wet concrete surface. ④ using hardener sufficiently wet concrete surface pretreatment and kept wet (touch has free liquid) for 40-60 minutes. Can be applied by brush, roller or spray coating methods. If the local site dry period, additional material should be kept moist. During this period should be used like a brush, mop or roller tool constant friction surface, so that the hardening agent can more effectively penetrate into the concrete. ⑤ When high temperatures, surface hardeners due to the evaporation of water quickly becomes sticky, you can spray a small amount of water to dilute the thickened hardener, but the amount should not be excessive. ⑥ remove remaining liquid: the use of plastic wiper or mop to remove the remaining liquid surface clean. ⑦ for faster penetration of the ground, after drying should be based on actual need to repeat steps 2 and 3. ⑧ conservation: dry ground after 24 hours of normal use. Hardener penetration of active ingredients gradually and cement reaction, often with a damp mop to clean the floor to promote penetration into the concrete inside the gel continues to react sooner to get the best strength. ⑨ finish: smooth dense ground after a period of time will produce a certain luster. If you can make the ground to obtain a certain luster polishing effect immediately. Use hardener in 7 days can be used to address conservation on the ground polishing machine polishing. Technical Requirements 3.1 The basic requirements grassroots concrete 1, A class of places: 1) the strength of concrete should be higher than C25; 2) the use of one-time pouring concrete from the construction method; 3) concrete thickness greater than 200 mm; 4) laying ≥φ12 double two-way or two-way single steel mesh; 5) requires the full backfill compaction. 2, Class B areas: 1) can be used fine aggregate concrete leveling method, the thickness should be greater than 5cm, the intensity should be greater than C20 above, the use of coarse sand and high-grade cement; 2) should be greater than the strength of concrete C20; 3) concrete thickness should greater than 120mm; 4) laying ≥φ6mm single bi-steel mesh; 5) requires the full backfill compaction.
