Key features

Ultrafine Particle Size: Average particle diameter of 150 nm, approximately 100 times smaller than cement particles.

High Silica Content: Contains 92% silica fume, acting as an effective pozzolanic material for concrete.

Enhanced Durability: Reduces permeability to chloride ions, protecting steel from corrosion in harsh environments.

Improved Strength: Significantly increases compressive strength, bond strength, and abrasion resistance of concrete.

Reduced Bleeding: Blocks pores and consumes free water, significantly reducing segregation and bleeding in fresh concrete.

Versatile Applications: Used in high-performance concrete, oil/gas well grouting, and remedial leak repairs.

Standard Compliance: Meets ASTM C1240 and EN 13263 specifications for cementitious mixtures.

High Specific Surface: Specific surface area ranges from 15,000 to 30,000 m2/kg for superior reactivity.

AI-Powered supplier vetting

SummaryGansu Mingruige Trading Co., Ltd. is identified as a Chinese trading company and manufacturer/factory operating in ferroalloys, coke, graphite, silicon-related products, and chemicals. The supplier reports ISO 9001 and GMP certifications, more than 10 production lines, 6–10 quality-control staff, and 41–50 years of R&D-engineer experience. It states annual output across several products, broad export-market coverage, self-operated import/export rights, and export sales representing 71%–90% of total sales. The supplier also describes organized purchasing, sales, quality-control, and finance departments, together with nationwide sales agencies and after-sales services. However, the provided information does not establish customer-specific cases, customization capabilities, or sufficient evidence to assess financial credibility. The stated production information is substantial, but the materials also identify the business as a trading company, so the precise allocation between owned manufacturing and trading...

Supplier typeThe supplier is explicitly classified as both a trading company and manufacturer/factory in one record, while another record identifies it as a trading company. It also reports a factory location in Tianzhu, Gansu, and operates more than 10 production lines, indicating manufacturing involvement, although the exact organizational scope of the factory is not fully clarified.

Product Q&A

Q:What is the difference between silica fume and fumed silica?

They are different materials. Silica fume is a by-product of silicon/ferrosilicon production with spherical particles, while fumed silica (pyrogenic silica) has a different production process, particle characteristics, and application fields.

Q:How does silica fume improve concrete durability?

It reduces permeability to chloride ions, which protects reinforcing steel from corrosion, especially in coastal regions, roadways using deicing salts, and saltwater bridges.

Q:What are the main applications of silica fume?

It is primarily used as a pozzolanic material for high-performance concrete. It is also used in oil and gas operations for well bore grouting and remedial leak repairs.

Q:How does silica fume affect the workability of fresh concrete?

It increases the surface area in the mix, causing slump loss proportional to its content. However, the mix remains highly cohesive despite the decreased slump.

Q:What standards does this silica fume meet?

The silica fume meets standard specifications ASTM C1240 and EN 13263 for use in cementitious mixtures.
