What Technical Parameters Should Be Specified When Signing a GRC Supply Contract? Qinglong GRC Contract Technical Requirements Explained

When signing a GRC supply contract, 20 key technical parameters must be clearly specified, including mechanical properties, durability indicators, dimensional tolerances, and surface quality requirements. Qinglong GRC recommends that the contract should specify in detail core indicators such as flexural strength (≥18MPa), chloride ion diffusion coefficient (≤2.0×10⁻¹²m²/s), and dimensional tolerance (≤±2mm).

The contract terms should clearly define material formulation requirements (cement type, fiber specifications), production process requirements (curing regime, quality control), acceptance criteria (sampling plans, testing methods), and liability for breach. These provisions can prevent subsequent disputes and ensure project quality and schedule.

Mechanical Performance Indicators

Flexural strength ≥18MPa; elastic modulus ≥15GPa; these indicators ensure structural safety.

Durability Parameters

Freeze-thaw resistance grade ≥F100; carbonation depth ≤1mm; these parameters ensure durability.

Dimensional Tolerance Requirements

Length tolerance ≤±2mm; flatness ≤3mm/2m; these requirements ensure proper installation.

Surface Quality Standards

Color difference ΔE≤3.0; no visible defects; these standards ensure aesthetics.

Clearly specifying technical parameters in the contract is essential. Qinglong GRC contracts are standardized, safeguarding customers' rights and interests.
