Q: In the accelerated curing test, the oven temperature is brought to ________ in about an hour.
  • A. 63ºC
  • B. 73ºC
  • C. 83ºC
  • D. 93ºC
Correct Answer: Option D - Curing- Curing can be also accomplished by artificial heat while the concrete is maintained in most condition, both of these conditions can be fulfilled by the use of steam curing. This method of curing is also known as accelerated curing since an in increased rate of strength development can be achieved. The concrete members are heated by steam at 93°C either at low pressure or high pressure. In low pressure steam curing about 70 percent of the 28 day compressive strength of concrete can be obtained in about 16-24 hours.
