Silica Fume Supplier in Malaysia for Concrete
- Also known as
- Microsilica
- Condensed Silica Fume
Silica fume supplier for concrete, precast, dry-mix, refractory and oil-well cement buyers in Malaysia. Also called microsilica or condensed silica fume, this very fine silica-rich material acts as a pozzolan and microfiller in engineered cementitious systems.
Densified and undensified powders address different bulk-handling and dispersion needs, while aqueous slurry supports wet dosing where its solids and water contribution can be built into the mix. Buyers compare silica content, moisture, loss on ignition, bulk density, retained material and physical form.
Silica fume is used in high-performance concrete, shotcrete, precast units, repair mortars, grouts, refractory castables and specified well-cement systems. It is not the same product as fumed silica, so the enquiry should name microsilica and the intended binder application clearly.
Send the required form, specification, application, quantity and delivery location with your enquiry. Packing, available technical documentation, quotation validity and delivery timing are confirmed for the offered grade.

Silica Fume grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Densified silica fume | densified grey powder | — | Ready-mix, precast, dry-mix and refractory production where improved bulk handling is preferred and the material will be dispersed during mixing. | The powder pack format is confirmed with the quotation. |
| Undensified silica fume | very fine low-bulk-density grey powder | — | Concrete, grout, shotcrete and speciality binder systems whose mixing process is designed to disperse undensified microsilica efficiently. | The powder pack format is confirmed with the quotation. |
| Silica fume slurry | pumpable aqueous dispersion at a specified solids content | — | Wet-dosed concrete and cementitious processes that prefer a pre-dispersed form and can account for the slurry water in the mix design. | The slurry concentration and pack format are confirmed with the quotation. |

Safety and handling
Keep powder sealed and dry, protected from moisture and uncontrolled dust release. Keep slurry containers closed and protect them from contamination and temperature extremes. Follow the handling information for the quoted form.
Common questions about Silica fume
Is silica fume the same as microsilica?
Yes. Microsilica and condensed silica fume are common names for silica fume, the ultrafine silica-rich particulate used in cementitious and refractory systems.
Is silica fume the same as fumed silica?
No. Silica fume is an industrial ultrafine material widely used as a pozzolan and microfiller in concrete, while fumed silica is a separately manufactured speciality silica used mainly for rheology, reinforcement and formulation control. They should not be substituted by name alone.
What is the difference between densified and undensified silica fume?
Densification increases bulk density and improves powder handling, while undensified material retains a lower bulk density and can require more specialised transfer and dispersion. The final selection depends on plant handling and the mixing system.
When should silica fume slurry be specified?
Slurry suits plants equipped for liquid dosing that prefer silica fume in a pre-dispersed form. Its solids content and water contribution must be known so the mix designer can account for both in the formulation.
Which silica fume specifications matter for concrete?
Buyers commonly compare silica content, moisture, loss on ignition, bulk density, retained material and physical form. The concrete producer should also state the mix, target performance and dosing method.
What details are needed for a Silica fume quotation?
Provide densified, undensified or slurry form, target specification, application, quantity and delivery location. Add packing preferences and required technical documents for confirmation with the quotation.
