| 摘要： | Q: Can you tell me whether the high pH of curing portland cement (typically ～12.4) might have any impact on the long-term performance of geogrids? A: It depends on the geogrid and its formulation. There are three categories of geogrid: (1) punched and drawn (polyethylene [PE] uniaxial, polypropylene [PP] biaxial and triaxial), (2) strap (polyvinyl alcohol [PVA]), and (3) woven, coated polyethylene terephthalate (PET). There are ramifications of high pH on geogrids only with the woven, coated PET over long-term exposure. Please consult the following references for more details: |
