About Fume Micro Silica

Go through wide range of Fume Micro Silica which is an amorphous polymorph of silicon dioxide, silica. This silica is an excellent admixture for concrete as it leads to better engineering properties. It reduces thermal cracking, improves durability, and increases strength. This silica provides a more uniform distribution and a greater volume of hydration products. This silica decreases the average size of pores in the cement paste. Fume Micro Silica is basically a finer particle than cement. It is produced by some chemical processing of the ash. This silica concrete has a number of construction applications. This silica is very cost effective and can be easily purchased by our clients at cheaper rates, as per their requirements.

Versatile Additive for Construction & Refractory

Fume Micro Silica is an essential component in various construction and industrial processes. Its fine particle size and high purity improve concrete strength and durability, making it highly desirable for applications such as shotcrete, precast elements, industrial flooring, and silica-based refractories. The product is widely used by distributors, exporters, manufacturers, suppliers, and traders across India.

Key Properties & Performance Advantages

This micro silica features a high silicon dioxide content, spherical amorphous particles, and a low loss on ignition. The material contributes to enhanced compressive and flexural strength, excellent dimensional stability at elevated temperatures, and reduced porosity in concrete mixes, leading to minimal water permeability and superior long-term performance.

FAQs of Fume Micro Silica:

Q: How is Fume Micro Silica used in concrete and construction applications?

A: Fume Micro Silica is added to concrete mixes to improve compressive and flexural strength as well as reduce porosity and water permeability. Its fine particle size fills gaps within the concrete matrix, leading to a denser and more durable final structure suited for high strength concrete, shotcrete, precast components, and industrial flooring.

Q: What are the main benefits of using Fume Micro Silica in refractory applications?

A: In refractory applications, the high silicon dioxide content and fine, spherical particles lend the product excellent dimensional stability and low thermal conductivity. This helps in producing silica-based refractories with superior resistance to high temperatures and mechanical stress, improving overall durability and performance.

Q: When should Fume Micro Silica be added to a mix and how much is typically used?

A: Fume Micro Silica is generally introduced during the batching or mixing stage alongside other dry components. The amount varies depending on project requirements, but common dosages are between 5% and 10% of the total cementitious material, optimizing strength and durability based on application specifications.

Q: Where should Fume Micro Silica be stored to preserve its quality and shelf life?

A: The product should be kept in dry, enclosed conditionsprotected from moistureto ensure a shelf life of up to 12 months. Proper storage maintains its fine powder consistency and prevents contamination or agglomeration, preserving its reactivity and effectiveness.

Q: What is the packaging size available for Fume Micro Silica?

A: Fume Micro Silica is offered in convenient packaging sizes of 10 kg, 20 kg, and 25 kg, making it suitable for both small-scale and large industrial requirements. These packaging options help minimize wastage and simplify transportation and storage on-site.

Q: How does the use of Fume Micro Silica affect water absorption and surface finish in concrete?

A: The materials highly reactive nature significantly reduces water permeability and porosity in the concrete, resulting in improved durability and lower water absorption. Its fine particle size helps produce a smooth, finely powdered surface finish in construction products.

Q: What process is involved in the incorporation of Fume Micro Silica into a mix?

A: Fume Micro Silica is blended thoroughly with cement and other aggregates, ensuring uniform distribution throughout the mix. Adequate mixing is critical for maximizing its performance benefitssuch as enhanced strength, durability, and reduced permeabilityacross a range of concrete and refractory applications.
