I have sealed an old abandon deep boring which was 220 feet long. First I poured small stone chips up to 7 feet and poured liquid cement mixed with Dr fixit up to 220 feet. My boring had PVC cashing which was 100 feet long. Please let me how long it will take to dry the cement to become fully concrete.

    What is "liquid cement" and what is "Dr. Fixit"? Don't those products' literature give you cure times? What level of cure are you asking about? – isherwood Jun 4 '19 at 17:31
  • "Fully concrete" is pretty subjective. Why do you need to know when it's fully cured? Does it need to support some weight or what? – JPhi1618 Jun 4 '19 at 17:37
  • About 24 years. The point of maximum strength is achieved much sooner. – Dan D. Jun 4 '19 at 18:36
  • Not sure what you a talking about Mousam. By bore do you mean a hole in the ground that is 220 deep ?? Please give us a more detailed description. PVC 100 feet long ? – Alaska Man Jun 4 '19 at 19:13

    Cured well enough for what purpose? It's not like a driveway or a sidewalk where you will have traffic or people walking on it. This is presumably to plug the well. At this point it's completed if you ask me. Concrete gets quite hard in a relatively short period of time and cures to about 50% of it's final strength in a week or so. Beyond 30 days it gets only marginally stronger over time. – jwh20 Jun 4 '19 at 21:29
