Terrazzo External Tiles Surface – Composition and Process Control

1. Composition Materials

(1) Cement

• Types:
  • For natural or dark terrazzo surfaces: Use Portland cement, ordinary Portland cement, or slag Portland cement (strength grade ≥ 32.5).
  • For light-colored terrazzo surfaces: Use white or white cement.
• Restrictions: Fly ash Portland cement must not be used.
• Batch Consistency: The same color terrazzo surface should use the same batch of cement.
• Quality Control: Cement must have a factory certificate or test data.

(2) Granules

• Source: Processed from hard and grindable rocks (e.g., dolomite, marble).
• Properties: Should have edges and corners, be clean, and free from debris.
• Size: 4-14mm (unless specified otherwise).
• Mix Ratio: Determined by design requirements.
• Storage:
  • Different types, specifications, and colors should be stored separately.
  • Stored on clean ground (e.g., mats) to prevent contamination.
  • Rinsed and dried before use.

(3) Pigments

• Properties: Must be light-resistant and alkali-resistant mineral pigments.
• Restrictions: Acid pigments must not be used.
• Mixing Ratio: 3% - 6% of the cement weight (or determined by experiments).
• Precaution: Excess pigment reduces surface strength.
• Batch Consistency: The same color surface should use the same batch of pigment from the same factory.

(4) Grid Strips

• Materials: Copper, glass, or colored plastic strips.
• Copper Strips: Must be straight before use.
• Specifications:
  • Copper Bars: 1200 × surface layer thickness × 1–2 mm
  • Glass Bars: Unlimited × surface layer thickness × 3 mm

2. Process Control

• The terrazzo external tiles surface layer should be monitored during both the construction and operation process.
• Quality Control Measures:
  • Follow construction standards and guidelines.
  • Ensure materials, mixing ratios, and application methods meet design requirements.
  • Implement regular inspections for quality assurance.
