Enhanced strength and durability

Step 1: Mix the silica fume with concrete

By adding 85u silica fume to concrete mixtures, the bond between cement particles is increased. This leads to higher compressive strength and improved durability of the concrete.

Step 2: Reduce permeability

Silica fume fills in the gaps in concrete, reducing its permeability. This helps to protect the structure from water and chemical penetration, increasing its lifespan.

Improved workability

Step 1: Adjust water-cement ratio

With the addition of silica fume, the water-cement ratio can be adjusted to improve the workability of the concrete mixture. This allows for easier placement and finishing of construction projects.

Step 2: Enhance pumpability

Silica fume improves the flowability of concrete, making it easier to pump and place in hard-to-reach areas. This helps in constructing complex structures with ease.

Decreased heat of hydration

Step 1: Control temperature rise

By using silica fume in concrete, the heat of hydration is reduced, which helps in controlling the temperature rise during the early stages of construction. This prevents thermal cracking and ensures long-term durability.

Step 2: Minimize shrinkage

The reduced heat of hydration also minimizes the shrinkage of concrete, leading to a more stable and crack-free structure. This is especially beneficial in large concrete pours where shrinkage can cause issues.Overall, the addition of 85u silica fume in construction offers numerous benefits, including enhanced strength and durability, improved workability, and decreased heat of hydration. By following these steps, construction projects can take full advantage of the benefits provided by silica fume to create long-lasting and reliable structures.
