TD-JS2 high-strength polymer mortar additives

Extension of building materials TD-JS2 high-strength polymer mortar additive I. Introduction Extension of TD-JS2 is made of high-strength polymer mortar polymer additives, specialty cementitious materials, high quality aggregates are mixed in a special process, with excellent bonding, crack, antifreeze, seepage, corrosion, resistance to chloride ion penetration, abrasion resistance, aging properties, suitable for water conservancy, port construction, highways, bridges, metallurgical, chemical, industrial and civil buildings and steel structures seepage, corrosion protection surface and the repair of reinforced concrete structures. Second, the use of 1, structural concrete reinforcement, waterproof plugging two air defense facilities, dams, ports seepage treatment 3, hot tub, landfills, chemical storage, chemical tank and other chemical resistance building 4, pavement , bridges, tunnels, culverts, concrete repair 5, industrial and civil roof, bathroom, basement seepage prevention treatment for 6, 7 waterproof steel and reinforced concrete, direct construction in the wet base surface, and a variety of substrates with good The bond strength. Third, the construction Introduction 1, the base surface treatment: In addition to cutting the old concrete surface eroded layer, rinse, remains substantially clean and solid. 2, the ratio of: cement is about 300kg, sand around 700kg, the additive is about 50kg, water (13-14)% use clean sand in the sand, mortar smear thickness 20-30mm appropriate, if applied thickness of less than When 10mm, with a particle size of less than 0.5mm can be considered fine sand. With a good stock should ensure that within 0.5-1 hours spent, mixing good mortar should pay attention to sun shelter. 3, large paved area available mechanical spraying, cell construction. A construction area should not be too large, should be staggered slitting block construction, each area should not be greater than 10m2, construction staggered intervals of not less than 24 hours. Layered construction, the left seam position should be staggered with each other. 4, immediately after the mortar should be finished paving mist spray the right amount of pressure and a smooth wiping, wiping pressure should not be repeated. In case of air bubbles should be punctured, 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 5-10mm, pending before the lower layer can be carried out during the construction finger touch dry. 5, after construction of the mortar layer shall conserve seven days. After the polymer mortar construction, surface means you should spray the conservation or covered straw mat, sacks kept moist touch dry after. Curing temperature should not end at 5 ℃.
