LCC curing effect on geogrids
April 1st, 2022
Q: Can you tell me whether modest warming of geogrids (e.g., due to heat generated by the curing of lightweight cellular concrete [LCC]) might impact the long-term strength or long-term modulus of geogrids? A: You need to know the maximum temperature due to the heat from hydration of the LCC. Most pozzolanic reaction temperatures (like […]
High pH effects geogrids?
April 1st, 2022
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 […]
