Prestressed pipe pressure slurry cementing materials adopted by the analysis

Prestressed pipe pressure slurry prestressed pipe pulp price prestressed pipe pressure paste manufacturer prestressed pipe pressure slurry cementing materials analysis technology adopted by the required mesh class mica ( In accordance with the quality plan, %) 1, 11. 0≤2. 0 lightweight material ( And 1 or less. 0 harmful substance content of organic matter ( Colorimetric method) Qualified qualified acid salt ( SO quality meter, %) ≤1. 0≤1. 0 ion quality meter, %) < 0. 010. 020. U natural sand silt content 3 or less. 0≤5. 0 clod content ( The monitoring 0 or less. 5≤1. 0≤2. 0 M artificial sand stone powder content value < L. 4 or 7 or less qualified. 0≤10. 0 ( In accordance with the quality plan, %) Methylene blue test p 1 MB. 4 or unqualified 2 or less. 0≤3. Natural sand 0 5, 0 or less, Night acid sodium solution method 8 8 of 10 or less or less strong or less sex after five cycles of quality loss, artificial sand single-stage biggest crush index (% %) < 2025 < 30 apparent density ( kg/m2) > Loose packing density (2500 kg/m2) 1350 empty rate ( ) 47 renew the above-mentioned technical requirements item class U class after JianJiLiao reaction test, by the amount of sand specimen, no crack, JianJiLiao reaction crack, colloid outside phenomenon, in the trial period of expansion rate should be less than 0. 10% of note: 1. Seconds according to the technical requirements are divided into 1 class, class, class, class 1 should be used in mixing and strength grade is greater than the C60; Ⅱ class should be used for strength grade C2000 and bed resistance, resistance, or other requirements of the wet earth; Classes should be used for less than C30 strength grade of concrete and building sand. 2. Natural sand seconds seconds including river, lake, mountain seconds the desalination of the sea, artificial sand and mixed seconds seconds including mechanism. 3. Refers to the particle size of stone powder content less than 0. 075 mm particle content of 4. Second temperature should not be in the grass roots, leaves, twigs, plastics, coal, slag and other sundry. 5. When the room round sexual and negative, should do consistence test 6 when required by the discrepancy in the BHB JianJiLiao reaction, prestressed pipe pressure slurry should be taken off JianJiLiao reaction of tracing technology.
