When energy is transferred during a chemical reaction, it is called enthalpy. Examine the changes that happen, the relationship to energy, heat, and temperature, exothermic and endothermic processes, and physical and chemical changes during enthalpy. ...
The hydration reaction of these cement chemicals result in significant increase in heat due to exothermic process in reaction. This chemical reaction between cement and water is known as hydration reaction. Water plays a key role inworkability of concreteand homogeneity of the concrete mix. Workabilit...
