The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Process**: The question asks about the nature of the setting of cement when water is added. We need to identify whether this process is exothermic, endothermic, or neither. 2. **Reaction of Cement with Water**: When water is mixed with cement, a chemical reaction occurs. This reaction is crucial for the setting of cement. 3. **Identifying the Type of Reaction**: The reaction between cement and water releases heat. This indicates that the reaction is exothermic. 4. **Formation of Products**: During the setting of cement, the cement reacts with water to form a gelatinous mass. This mass eventually hardens into a solid structure, which is a three-dimensional network of silicates and aluminates. 5. **Conclusion**: Since the process of setting cement involves the release of heat, we conclude that the setting of cement is an exothermic reaction. ### Final Answer: The setting of cement is an **exothermic** reaction. ---

Assertion: When cement is mixed with water and left as such, it becomes hard mass. Reason: Setting of cement is exothermic process.

Cement is one of the most important building material of the present time. It is a dirty greyish heavy powder containing calcium aluminates and silicates. The important raw materials neede for the manufacture of cement are limestone, clay and gypsum. the main step in the manufacture of cement is the heating of raw meal or slurru in the rotary kiln at a very high temperature 1400-1600^(@)C . Finally 2% or 3% gypsum is added. When cement is mixed with water and left as such for sometime, it becomes a hard mass. This is known as setting of cement. It is believed that varous aluminates and silicates present in the cement form hydrates with water which seperate in the form of gel. the gel formed start losing water partly by evaporation and partly by forming hydrates with unhydrated constituents. this results in the formation of a hard mass. Setting of cement is
