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.
Concreteâs strength is in part a function of the temperature at which it cures. Normal compressive strength is based on curing concrete at its ideal curing temperature, 72 degrees F for a period of 28 days.Warmer temperatures reduce the cure time.On the other hand, cooler temperatures increase the length of the cure period.s long as the differential between ambient air temperature and concrete temperature is minimal, concrete poured under cold conditions will produce higher than ordinary ultimate strengths and better long-term durability. Site preparation. The secret to a good cold weather pour begins with good site preparation.
