How to prepare epoxy grout anticorrosive processing!

1, according to the engineering properties to choose high quality cement. In the water level change, repeatedly dry-wet alternate or freeze-thaw parts of a structure, appropriate chooses sulfate resistant cement, slag cement or alumina cement, or choose content of tricalcium aluminate 42 strength grade is less than 6%. 5 wow alite-suiphoaluminate cement or general wow acid salt, cement strength grade progress construction planning, epoxy grout strength grade is usually not less than C30, epoxy grout compactness, per m3 of epoxy grout cement dosage is more than 350 kg, orthopaedic choose secondary distribution, sand ratio is more than 38% water cement ratio is less than 0. 50, mixing water reducing agent and air entrained agent progress compactness, cold does not have to avoid early steam maintenance, etc. 2, on the basis of building types and types of corrosion on the ground, underground with acid or alkali orthopaedic/wow dioxide content is higher the meantime acid function, the better, such as common granite, basalt stone and quartzite acid better stone, high content of calcium oxide and magnesium oxide dear see good functionality, such as dolomite, limestone and marble, etc. 3, thickening reinforcement layer maintenance. Corrosion of underground part of the maintenance of the thickness should be increased 5 - than planning 15 mm, to resist outside for a long time. Construct the external adopt besmear brushs anticorrosive 1, anticorrosion coating. In the coating corrosion resistant coating epoxy grout structure appearance, commonly used coating has chlorosulfonated polyethylene acid and alkali proof coating. Bituminous paint, epoxy coatings, anti-corrosion materials such as the coal tar. 2, plate ( Block) Wood veneered anticorrosion. On the corrosion resistance of epoxy grout construction site with a layer of corrosion plates corrosion cement pastes. Commonly used plate ( Block) Material with acid ceramic plate, granite slab, cast slabs, acid-resistant steel brick, etc. , are commonly used with asphalt cement paste data, asphalt mortar, sulphur, sodium silicate cement and mortar cement, mortar, etc. 3, coil cover. Choose one felt two oil usually foundation or two felt three oil corrosion, put 2 - exposed parts of the important project Three layers of glass fiber reinforced plastic, make the structure and the external corrosion of soil or groundwater, air cut off. 4, plaster corrosion. In general appearance with a layer of epoxy grout structure corrosion cement or mortar, commonly used epoxy coal tar daub. Resin cement or mortar, etc.
