Initial setting of cement is mainly due to

Options

A. hydration and get formation
B. dehydration and get formation
C. hydration and hydrolysis
D. hydration and oxidation

Answer

**Step-by-Step Solution:**

1. **Understanding Cement Setting**: The initial setting of cement refers to the process when the cement paste begins to stiffen significantly after mixing with water. This is a crucial phase in the use of cement for construction.

2. **Hydration Process**: The setting of cement is primarily due to a chemical reaction known as hydration. When water is added to cement, it reacts with the compounds present in the cement to form various hydration products.

3. **Formation of Gel**: During hydration, one of the key products formed is a gel-like substance. This gel formation is responsible for the stiffening of the cement paste, marking the initial setting.

4. **Conclusion**: Therefore, the initial setting of cement is mainly due to the hydration process and the subsequent formation of gel, which leads to the stiffening of the cement paste.

**Final Answer**: The initial setting of cement is mainly due to hydration and gel formation.
