Is It Possible to Convert Dry Mortar or Plaster into Cement Powder?

The simple answer to the question 'How do you make cement powder from dry mortar or plaster?' is: No, it is not possible. Cement is always in a powdered form and undergoing a chemical process during hydration.

Understanding Cement and Its Powder State

Cement is a finely ground material made from limestone, clay, and other additives. When mixed with water, it undergoes a chemical reaction known as hydration, which transforms it into a solid, rock-like mass.

The powder form of cement is essential for effective mixing and application. Hydrated cement, however, loses its powdered state and transforms into a hard, immobile structure.

The Process of Hydration and Its Irreversibility

When cement is combined with water, a chemical reaction called hydration occurs. This process is irreversible, meaning the resulting hydrated cement cannot be converted back into its original powdered form.

The hydration process is a complex series of reactions involving the formation of calcium silicate hydrates (CSH). As water molecules interact with the cement, they form strong bonds that solidify the material.

Equivalence to Flour and Bread Analogy

Your question can be compared to asking 'how do you make flour out of bread.' Flour is one of the ingredients used to make bread, but the process of mixing flour with water, yeasts, and other ingredients and subjecting it to baking transforms the flour into bread. Once the flour has been transformed into bread, it is no longer in its original powdered form.

A similar principle applies to cement and mortar. Mortar is a mixture of cementitious materials, sand, and water, often used in masonry work. When used correctly, the mortar undergoes the hydration process and becomes a stable, solid structure, rather than reverting back to its powdered state.

Uses and Applications of Cement, Mortar, and Plaster

Cement is widely used in construction and civil engineering projects. It is a key component in concrete, which is used for buildings, roads, bridges, and many other infrastructure projects. Cement is also used in mortar, a mixture of cement and sand that is used to bind bricks and stones together in construction.

Plaster, another form of cement-based material, is used for wall finishing, ceiling finishes, and as a backing for paint. It can be applied to create smooth, even surfaces and is often used in interior decoration.

Finding Solutions for Your Needs

If you require cement powder for specific applications, it is best to purchase it directly from suppliers who specialize in cement and construction materials. Mixing existing mortar or plaster to create cement powder is not advisable, as it does not produce a suitable product and may result in substandard construction practices.

For proper repair and maintenance of structures, it is important to follow the appropriate recommendations and guidelines provided by industry professionals. Consulting with a construction expert or a professional in the field can ensure that your project is completed with the highest standards of quality.

Conclusion

In summary, cement in its powdered form cannot be converted back into a usable form from mortar or plaster. The hydration process that occurs when cement is mixed with water is irreversible, making it essential to use the correct materials for specific applications in construction and civil engineering projects.
