hpi concrete cure time
hi,
in our current project we use hpi concrete for the roof slab of water reservoir.
this is my first experience with hpi concrete. after first concrete pure we found, that concrete hardened much faster than the regularly used concrete (about 2 times faster). concrete was placed in january.
  we think about using hpi concrete for another water containing structure and the construction scheduled for summer time. i have a concern that it will be difficult to place concrete in high summer temerature, because of fast curing time.
  if anyone worked with hpi concrete in summer, please let me know.
thank you
