2. Accelerated curing - Wikipedia

   en.wikipedia.org/wiki/Accelerated_curing

   Accelerated curing is any method by which high early age strength is achieved in concrete. These techniques are especially useful in the prefabrication industry, wherein high early age strength enables the removal of the formwork within 24 hours, thereby reducing the cycle time, resulting in cost-saving benefits.

3. Cement accelerator - Wikipedia

   en.wikipedia.org/wiki/Cement_accelerator

   A cement accelerator is an admixture for the use in concrete, mortar, rendering or screeds. The addition of an accelerator speeds the setting time and thus cure time starts earlier. [ 1 ] This allows concrete to be placed in winter with reduced risk of frost damage. [ 2 ]

4. Concrete - Wikipedia

   en.wikipedia.org/wiki/Concrete

   The American Concrete Institute (ACI) definition of cold weather placement, ACI 306, [128] is: A period when for more than three successive days the average daily air temperature drops below 40 °F (~ 4.5 °C), and; Temperature stays below 50 °F (10 °C) for more than one-half of any 24-hour period.

5. American Concrete Institute - Wikipedia

   en.wikipedia.org/wiki/American_Concrete_Institute

   The American Concrete Institute (ACI, formerly National Association of Cement Users or NACU) is a non-profit technical society and standards developing organization. ACI was founded in January 1905 during a convention in Indianapolis. [1] [2] The Institute's headquarters are currently located in Farmington Hills, Michigan, USA. ACI's mission is ...

6. Properties of concrete - Wikipedia

   en.wikipedia.org/wiki/Properties_of_concrete

   The ultimate strength of concrete is influenced by the water-cementitious ratio (w/cm), the design constituents, and the mixing, placement and curing methods employed.All things being equal, concrete with a lower water-cement (cementitious) ratio makes a stronger concrete than that with a higher ratio. [2]

8. Concrete degradation - Wikipedia

   en.wikipedia.org/wiki/Concrete_degradation

   The curing of concrete when it continues to harden after its initial setting and progressively develops its mechanical strength is a critical phase to avoid unwanted cracks in concrete. Depending on the temperature (summer or winter conditions) and thus on the cement hydration kinetics controlling the setting and hardening rate of concrete ...
