Polymer mortar - Polymer mortar purposes

What is polymer mortar polymer mortar is a kind of has the adhesion of polymer materials, but also has the new type of inorganic material durability of concrete repair mortar; High compressive strength, rapid curing, bonding performance is good; Have very good water retention performance and crack resistance, high alkali resistance, resistance to ultraviolet radiation; Easy to operate, can damp base construction, healthy environmental protection. Make construction procedure is simple, convenient, and concrete durability, shorten time limit for a project, to ensure efficiency. What are the purposes of polymer mortar with stainless steel wire mesh reinforcement method applies to all structure reinforcement of flexible structures. Particularly applicable to civil engineering and construction of typical bending structure, reinforced concrete flat beams of Bridges, also applies to the central part of the pier of the axis of the main tower, and the crack part of the road. The previous system of reinforced concrete structures have the same. The basic principle of this method are: stainless steel wire mesh by adhesive strength and bending strength of excellent permeability polymer mortar, and the original concrete to form an organic whole. Stainless steel wire mesh to increase rigidity, while increase the load resistance force, can prevent the durability of the lower as a result of polymer mortar. A honeycomb, holes, cracks, concrete protective layer damaged tendons defect leakage, can use type polymer mortar repair repair reinforcement; Protective layer thickening, concave and convex surface smoothing, the old concrete surface repair, etc. ; Extend the service life of concrete to improve the durability of concrete; Has the very good permeability resistance, crack resistance, ageing resistance and alkali resistance performance; For a variety of materials have good adhesive force. Polymer mortar the usage of the basic requirements and processing, at the grass-roots level surface should be smooth, rough, clean, no pollution, no float ash, dusting, empty drum, there should be no cracks. Before the construction state of application of high pressure water washing and keep moisture, but can not have water. When binding, can besmear brushs interface treatment agent in advance. Polymer mortar material preparation, powder: water according to the quality than 100:13 said to take place. The actual dosage of 90% of the water into the powder mixing evenly, then gradually into the remaining 10% water and stir without aggregation, with good size should guarantee at 0. Out of 5-1 hour. Polymer mortar construction aspect, in the wet concrete base surface evenly over the interface treatment agent (first A: b = 3:1) 。 Polymer mortar shoulds not be too great a construction area, should be a partition to stagger the construction, each area should not be greater than 10 square meters, the interval of staggered construction should not be less than 24 hours. Layered construction, seam location should be staggered to each other. After the polymer mortar paving should immediately press and a smooth, should not be repeatedly put pressure. In case of bubbles should be punctured compaction, surface should be compacted. Facade or on the surface of the roof should be layered construction layer thickness is greater than 10 mm. Thickness of each layer of plaster suitable for 5 to 10 m, to be a not to touch on the lower layer before the construction. Polymer mortar
