ALVERTEX® PRIMIX-70 SUPER WHITE

Description

ALVERTEX® PRIMIX-70 SUPER WHITE is a pure hydraulic calcium aluminate binder of premium quality, formulated without any additives. It is engineered to deliver maximum whiteness, exceptional hydration reactivity and high early strength development. Its rich calcium aluminate phase content makes it ideal both as a standalone binder and as a key component of ternary systems (combined with Portland cement and gypsum) for precise ettringite matrix control.

The product is specially developed for high-end dry mix formulations and specialty technical mortars where colour saturation, vividness and extreme wear resistance are critical. It contains no detectable crystalline silica or water-soluble chromium (Cr VI), has zero VOC content, and fully complies with stringent European environmental regulations.

Advantages

  • Outstanding whiteness (92–94 on the Hunter scale) — guarantees maximum brightness and colour saturation in decorative and architectural mixes, removing any aesthetic limitations.
  • Ultra-early strength — reaches compressive strengths of 30 MPa as early as 6 hours, significantly accelerating production and construction cycles.
  • Chemical purity with no additives — contains only calcium aluminate phases (CA, CA₂), eliminating unpredictable reactions in complex formulations and ensuring result consistency.
  • High fineness (4300–4500 cm²/g Blaine) — the fine grinding enhances hydration activity and improves the workability of final mixes.
  • Environmental safety — classified as non-hazardous, fully REACH compliant, emits zero VOCs, and is free from dangerous impurities.
  • Versatility in ternary systems — enables precise expansion and setting control when combined with Portland cement and gypsum, making it indispensable for self-levelling underlayments and high-performance grouts.

Applications

  • Self-levelling underlayments and cement-based technical screeds.
  • High-end architectural and decorative mortars.
  • Terrazzo and cement-based grindstone flooring systems.
  • Premium technical mortars and tile grouts requiring absolute colour stability.
  • Dry mixes for precision repair compounds and white concrete products.

FAQ

It is a high-whiteness hydraulic calcium aluminate binder based on CA and CA₂ phases, developed for demanding dry-mix formulations and specialty technical mortars.

Hunter Whiteness is 92–94 with a guaranteed minimum of ≥90. The representative batch measured 93.1.

The stated range is 30–40 MPa at 6 hours, 50–65 MPa at 24 hours and 55–67 MPa at 72 hours. Guaranteed minimums are 25, 40 and 42 MPa respectively.

Yes, the product is intended for both standalone use and for ternary systems with Portland cement and gypsum.

Yes, its high whiteness and low Fe₂O₃ content (0.05% in the representative batch) make it ideal for white and coloured cementitious systems. For precise colour evaluation, it is recommended to measure L, a, b* and ΔE in the specific formulation.

Store in a dry place, in the original unopened packaging, off the ground. Under these conditions, the guaranteed shelf life exceeds 180 days.

No, full interchangeability is not guaranteed. The product has a strong comparable technical profile, but final suitability and dosage must be confirmed through testing in the customer’s formulation.

Start with a 1:1 substitution in the current formulation, then compare water demand, flow, setting time, early strength and colour. If necessary, optimize the dosage and component balance.

It is recommended to monitor water demand, flow and workability retention, initial/final setting, strength at 6/24/72 hours and 28 days, CIELAB colour parameters, particle-size distribution, residue on 90 μm sieve, colour stability and efflorescence, and abrasion resistance where relevant.

No, the material is classified as non-hazardous, contains no detectable free crystalline silica or water-soluble chromium (Cr VI), and has zero volatile organic compounds.
