Trusted Silica Fume Supplier in Surat for High-Strength Concrete
Microsilica 90 is designed to provide a qualitative boost to concrete, particularly in concrete mixes where additional cementitious material is required beyond cement and fly ash.
The material is a mineral admixture comprising very fine solid glassy spheres of silicon dioxide (SiO₂), with a particle size described in the supplied technical document as around 100 times smaller than the average particle size of cement and fly ash.
Microsilica 90 supports compressive, flexural and bond strength while helping reduce concrete permeability and supporting reinforcement protection.
Silica Fume (Microsilica 90) for High-Strength Concrete
Microsilica 90 is designed to provide a significant qualitative boost to concrete. The supplied technical document explains that high-strength concrete mixes require additional cementitious material beyond cement and fly ash.
Microsilica 90 plays an important role in increasing compressive, flexural and bond strengths in concrete.
The document describes Microsilica 90 as a mineral admixture consisting of very fine solid glassy spheres of silicon dioxide (SiO₂) .
Its particle size is described as around 100 times smaller than the average particle size of cement and fly ash.
What is Silica Fume / Microsilica 90?
Microsilica 90 is a fine amorphous silica-based mineral admixture used in concrete mixes where enhanced concrete performance is required.
According to the supplied technical document, the silica reacts with the weaker calcium hydroxide released during cement hydration and forms additional calcium silicate hydrate (C-S-H) .
The resulting higher concentration of strong calcium silicate hydrate is described as contributing to greater concrete strength.
Pozzolanic Action
Microsilica 90 reacts with calcium hydroxide during cement hydration and forms additional C-S-H, as described in the supplied document.

Microsilica 90 Applications & Roles
Why Use Microsilica 90 in Concrete?
Strength, permeability, reinforcement protection and ASR-related performance described in the supplied technical document.
Higher Compressive Strength
The supplied document describes Microsilica 90 as supporting higher compressive strength through its pozzolanic action and formation of additional C-S-H.
Flexural & Bond Strength
Increasing compressive, flexural and bond strengths is identified as a key role of Microsilica 90 in the supplied document.
Reduced Water Permeability
The very fine particle size reduces the average pore size in concrete and, according to the document, drastically reduces water permeability.
Reinforcement Protection
The document states that Microsilica 90 reduces chloride ion permeability and imparts high electrical resistivity, helping protect reinforcement steel.
Reduced ASR Risk
The supplied document describes Microsilica 90 as helping combat Alkali-Silica Reaction by binding calcium hydroxide together with sodium and potassium oxides.
Reduced Damp & Leakage Troubles
The supplied technical document identifies reduced instances of damp and water leakage troubles as an additional functional benefit.
Lower Water-Binder Ratio
The document states that Microsilica 90 changes concrete rheology and reduces the water-binder ratio, contributing to higher compressive strength.
Denser Concrete Matrix
Fine particles and additional hydration described in the document contribute to more uniform distribution and greater hydration in concrete structures.
Improved Concrete Life
The supplied document describes Microsilica 90 as improving the life of concrete through reinforcement protection and reduced ASR.
Benefits of Microsilica 90
Key benefits described in the supplied Microsilica 90 technical document.
Higher Compressive Strength
Supports higher compressive strength through additional C-S-H formation.
Flexural & Bond Strength
The document identifies increased flexural and bond strength as important benefits.
Reduced Permeability
Helps reduce concrete pore size and water permeability.
Reinforcement Protection
Helps protect reinforcement steel through lower chloride permeability and high electrical resistivity.
Reduced ASR
Helps combat Alkali-Silica Reaction as described in the supplied technical document.
Reduced Damp & Leakage Troubles
Reduced permeability is identified as a functional benefit related to damp and water leakage troubles.
Lower Water-Binder Ratio
The document states that Microsilica 90 reduces the water-binder ratio.
Improved Concrete Life
Supports longer concrete life through reduced permeability, reinforcement protection and ASR control.
Pozzolanic Action
Silica reacts with calcium hydroxide during cement hydration to form additional C-S-H.
Recommended Microsilica 90 Addition
The supplied technical document recommends mixing Microsilica 90 between 5–10% of the cement used in the concrete mix for excellent performance.
Actual dosage and concrete performance should be determined according to the applicable mix design, materials and project requirements.
M-70 Concrete Trial Performance
The supplied technical document reports M-70 concrete trial mixes with Microsilica 90 added in the ratio of 1:10 of cement and cube-test compressive-strength results at 3, 7 and 28 days.
Result 2
| Age | Weight (kg) | Compressive Strength (N/mm²) | Average |
|---|---|---|---|
| 3 Days | 8.890 / 8.860 / 8.830 | 54.48 / 59.11 / 61.28 | 58.29 N/mm² |
| 7 Days | 8.860 / 8.790 / 8.970 | 75.91 / 74.75 / 70.60 | 73.77 N/mm² |
| 28 Days | 8.910 / 8.690 / 8.880 | 102.83 / 98.11 / 90.52 | 97.16 N/mm² |
Reported 28-Day Performance
According to the supplied document, the M-70 grade mixture was expected to give a compressive strength of 80–82 N/mm² after 28 days. With Microsilica 90 at 10% of cement weight, the document reports that the average strength achieved was 18% better.
These figures are the trial results reported in the supplied Microsilica 90 document and should not be treated as a universal performance guarantee. Actual concrete performance depends on mix design, materials, dosage, testing and project conditions.
