Many people who use creatine gain weight. This is because creatine causes the muscles to hold water, not because it actually builds muscle. 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.
Typical concrete takes 28 days (4 weeks) to cure. Prior to the 28 days concrete still has moisture in it that weakens the strength of the concrete. If you seal it prior to 28 â¦ days there is a chance you will be sealing in some of that moisture and hence weakening the integrity of the concrete.hat depends on the concrete, as well as weather conditions, and the load the concrete would be subjected to. Concrete gains strength over time and the usual benchmarks are 7 â¦ days, and 28 days. At 28 days concrete has usually cured to nearly its maximum strength.
