There is some concern that combining creatine with caffeine and the herb ephedra (also called Ma Huang) might increase the chance of having serious side effects such as stroke.
Concrete retained in forms or covered with insulation seldom loses enough moisture at 40 to 55 degrees Fahrenheit) to impair curing. However, drying from low wintertime humidities and heaters used in enclosures is a concern.
What you describe as concrete is actually mortar. Sand and cement combine to mix mortar. (used ro setting bricks, for example) Sand and cement and an aggregate (small rocks) combine to make concrete. Any cementatious product reaches full cure in 29 days.Full cure being structurally safe, for example, that is when a tilt-up concrete wall can savely be lifted into place.oncrete cures essentially forever, although after 29 days, the rate of cure is dramatically reduced. For around home use, you are wondering how soon can you get onto the next phase of the project-whatever that project may be. It does depend on the project as to whether you will be safe or not.
