  1. Heat of hydration and the importance of controlling it

    The reactions that bring about the hardening of hydraulic cement pastes are exothermic, that is, they are accompanied by the liberation of heat. This heat of hydration is an important factor in mass concrete …

  2. Heat of Hydration Effects in Concrete Structures

    Mar 1, 1992 · The setting and hardening process of concrete is accompanied by the development of heat of hydration temperatures. These present nonlinear distributions leading to tensile stresses that …

  3. Standard specifications for cements - American Concrete Institute

    Sometimes called moderate-heat cement, it is intermediate between Type I and the low-heat Type IV cement. If moderate heat of hydration is desired, however, the optional limit on heat of hydration …

  4. ACI defines Mass Concrete as “any volume of concrete with dimensions large enough to require that measures be taken to cope with generation of heat from hydration of the cement and attendant …

  5. Modeling the Heat Development of Concrete Associated with Cement …

    Apr 1, 2007 · It is demonstrated how a simple three-parameter-model is sufficient to formulate the development of heat from the cement hydration process. Furthermore, the heat development is used …

  6. Heat of Hydration of High-Strength Concretes - American Concrete …

    Nov 1, 1990 · Heat of hydration of a selection of high-strength concretes has been investigated by means of a so-called semiadiabatic calorimeter test. The temperature development within a …

  7. Heat of Hydration Models for Cementitious Materials

    Jan 1, 2005 · The heat of hydration of concrete under different curing temperatures can be characterized with knowledge of the temperature sensitivity (activation energy), the degree of …

  8. This report presents a detailed discussion of the effects of heat generation and volume changes on the design and behavior of mass concrete elements and structures, a variety of methods to compute …

  9. Mass concrete is any volume of concrete with dimensions large enough to require that measures be taken to cope with the generation of heat from hydration of the cement and attendant volume change …

  10. Modeling Hydration of Cementitious Systems - American Concrete …

    Mar 12, 2012 · The final model provides a useful tool to assess the temperature development of concrete mixtures and thereby facilitate the prevention of thermal cracking and delayed ettringite …
