Abstract. global production of cement has grown very rapidly in recent years, and, after fossil fuels and landuse change, it is the thirdlargest source of anthropogenic emissions of carbon dioxide. the availability of the required data for estimating emissions from global cement production is poor, and it has been recognised that some global estimates are significantly inflated.

Enthalpy | Chemical Reactions Scribd
Enthalpies are the enthalpy change (i.e. heat absorbed) when some amount of a compound is formed from its elements in their standard states under standard conditions. the magnitude of any change depends on the temperature, pressure, and state (gas, liquid, or solid crystalline form) of the reactants and products. the standard state is its pure form at (1 atm) while the temperature is set at.
