Beijing Beijing concrete curing agent manufacturers Manufacturers concrete curing concrete curing agent agent I. Overview concrete curing agent is a polymer emulsion sprayed on the concrete surface, can quickly form a dense film to prevent premature evaporation of free water inside the concrete, in order to achieve self-curing concrete to prevent concrete cracking purposes. Etc. Second, use? Pavement Engineering highways, airport runways, garages, parking lots? Overall situ concrete project? Construct complex engineering structures and products section strange? Difficult for traditional conservation cement concrete works Beijing concrete curing agent manufacturers Beijing concrete curing agent manufacturers Third, the technical performance? The use of concrete curing agents have good water retention, at 5 ℃ ~ 40 ℃ conditions of construction, curing agents sprayed concrete strength than cover straw bags of concrete strength slightly water conservation improve, shrinkage is reduced, the bending strength increased. ? Use of this agent curing concrete surface, does not affect their project finishes. ? This product is non-toxic, non-flammable, non-corrosive, easy construction operations, site clean. No. Item Specifications 1 effective water retention,% ≥90 2 compressive strength ratio, (28d)% ≥95 3 Drying time, h ≤4 4 film after immersion in water solubility of sparingly soluble five qualified four heat-resistant film, using ? method immediately after spraying or brushing the concrete form removal curing agent, or after the initial setting of concrete curing compound, as long as the proper understanding of spraying time, you can achieve good conservation results;? The agent can be sprayed with a backpack sprayer, simple and feasible , the discharged liquid requirements and seeks uniform spray mist, missed spray, in order to ensure the conservation of mass, continuous spray two times as well, requiring a second time with the first pass into the spray vertically. ? When the rain is not suitable for spraying, but the rain after the film after spraying curing agent, did not affect the conservation effect. ? When the spray nozzle is about 30cm away from the concrete surface is appropriate, after spraying is completed, the application of water to the sprinklers, nozzles and other equipment clean, to prevent blockage of the equipment when used again. ? Also be brushing twice appropriate. Five, the amount of packaging? 8 to 10 square meters / kg, 50 kg / plastic drum
