The durability of cement concrete is usually improved by the addition ...
Durability of concrete may be defined as the ability of concrete to resist weathering action, chemical attack, and abrasion while maintaining its desired engineering properties. For a durable concrete, use of lowest w/c ratio is the fundamental requirement to produce dense and impermeable concrete. Lowering the water-cement ratio will lead to increase in the cement content thus increasing the durability. Mix must be designed to ensure cohesion and prevent segregation and bleeding. If cement is reduced, then at fixed w/c ratio the workability will be reduced leading to inadequate compaction. However, if water is added to improve workability, water / cement ratio increases and resulting in highly permeable material.

Durability of Cement Concrete
Durability of cement concrete is a crucial aspect that needs to be considered during its construction. The addition of certain materials can improve the durability of cement concrete. One such material is cement itself.
Effects of Adding More Cement
Adding more cement to the concrete mix can have the following effects:
1. Increased Strength: Cement is one of the primary components that give strength to concrete. Adding more cement to the mix can increase the strength of the concrete, making it more durable.
2. Better Resistance to Environmental Factors: Cement concrete is exposed to various environmental factors like moisture, temperature changes, and chemicals. These factors can cause damage to the concrete, reducing its durability. The addition of more cement can enhance the resistance of the concrete to these factors, making it more durable.
3. Improved Workability: The workability of concrete refers to its ability to be easily molded and shaped. The addition of more cement can improve the workability of the concrete, making it easier to work with during construction.
Conclusion
In conclusion, adding more cement to the concrete mix can improve its durability in multiple ways. It can increase the strength of the concrete, enhance its resistance to environmental factors, and improve its workability. Therefore, it is a common practice in the construction industry to add more cement to the concrete mix to make it more durable.
