As an expert in the field of construction materials, I can provide you with a comprehensive understanding of the use and properties of cement. Cement is a fine powdery substance that, when mixed with water, forms a paste that can be used to bind other materials together. It is a crucial component in the creation of mortar, plaster, and concrete, which are all essential in the construction industry. However, using cement on its own is not typically recommended due to its properties and the intended applications for which it is used.
Cement Composition and Setting Process:
Cement is primarily composed of calcium silicates, which react with water to form a hard, durable material. This process is known as hydration and is exothermic, meaning it releases heat. The hydration process involves the formation of complex crystalline structures that give cement its strength. However, the hydration process requires a certain amount of time to reach its full strength, which is why it is often mixed with other materials to create a more immediate and versatile building material.
Strength and Durability:
While cement is strong once fully hydrated, it is brittle and prone to cracking if not reinforced or mixed with other materials. This is why it is rarely used on its own for structural applications. Instead, it is combined with aggregates (such as sand and gravel) to create concrete, which is much stronger and more durable.
Use in Mortar and Plaster:
Cement is often used in the form of mortar, which is a mixture of cement, sand, and water. Mortar is used to bind bricks or stones together in masonry construction. Similarly, cement can be used to make plaster, which is a mixture of cement, sand, and water that is applied to walls and other surfaces to create a smooth, durable finish.
Concrete Production:
When cement is mixed with sand, gravel, and water, it forms concrete. Concrete is a composite material that is incredibly strong and durable, making it ideal for a wide range of construction projects. The addition of steel rebar can further enhance the strength and flexibility of the concrete, allowing it to be used in the construction of bridges, skyscrapers, and other large structures.
Environmental Considerations:
It's also important to note that the production of cement has significant environmental impacts. It is energy-intensive and contributes to carbon dioxide emissions. As such, there is ongoing research into more sustainable alternatives and methods for producing cement.
Conclusion:
In summary, while cement is a critical component in the construction industry, it is not typically used on its own. Its properties make it more suitable when combined with other materials to create stronger, more versatile building materials like mortar, plaster, and concrete. Understanding the role of cement in these mixtures is key to its proper and effective use in construction projects.

Whether it's a small garden wall, a large braai, or a home addition, it is guaranteed that you will be using cement during the process. While cement on its own is not very strong, when combined with other materials cement takes on new form and is used as mortar, plaster and for concrete.
