Five core materials for concrete strength, durability, and efficiency.

The details below are curated from your archived technical and product files, now structured for easier reading and faster enquiry decisions.

Fly ash based bricks and material application

Ashcrete (Fly Ash)

Pozzolanic MaterialConcrete Admixture

Fly ash is a fine mineral powder recovered from coal combustion and used as a supplementary cementitious material. In concrete, it helps improve workability, reduce bleeding, and provide denser matrix performance over time. Learn more in our What is Fly Ash guide.

  • Primarily silica, alumina, and iron rich material
  • Supports smoother finishes and sharper architectural detailing
  • Used in RMC, cement blending, blocks, and paver applications
Cenosphere particles under optical microscopy

Cenosphere

Lightweight FillerSilica-Alumina Sphere

Cenosphere is a naturally occurring inert hollow sphere from thermal fly ash streams. It is known for weight reduction and flowability improvements across multiple industrial applications.

  • Reduced end-product weight
  • Improved flow and even filler dispersion
  • Lower resin demand and lower raw material loading
  • Resistant to water, solvents, acids, and alkalis
Silica fume sample used in high strength concrete

Star Silica (MS-85 and MM-92 Micro Silica)

ASTM C1240Densified Micro Silica

Legacy records describe Star Silica as densified dry silica fume supplied mainly in jumbo bags. It is positioned for precast and ready mixed concrete where high strength and low permeability are required. See our Quality page for standards-focused context.

  • Typical SiO2 range listed in archive: 85-94%
  • Supports higher early and ultimate strength
  • Improves durability by reducing permeability
Meta kaolin particle microstructure

StarPozz (Meta Kaolin)

Highly ReactiveStrength Enhancer

StarPozz is presented in archived files as MK-1 and MK-2 highly reactive meta kaolin for concrete mixes requiring high early strength and improved durability.

  • Archive values include SiO2: 52-54% and Al2O3: 40-44%
  • Low loss on ignition values indicated in archived table
  • Suitable for high-strength and durability-driven applications
Samples of ground granulated blast furnace slag

STAR GGBS (Ground Granulated Blast Furnace Slag)

ASTM C989BS 6677

STAR GGBS is positioned for use as a cement additive where higher durability and controlled heat of hydration are required. Archived content highlights compliance references and tested characteristics. For matching grade and volume, use our enquiry form.

  • Feature claims in archive: high hardening strength and durability gains
  • Fine powdered form from granulated blast furnace slag processing
  • Designed for concrete and infrastructure grade blending
