Concrete is the most widely used building material globally, and compressive strength is the core indicator for determining structural quality.
The 28 day standard maintenance testing process commonly used in the industry has significant lag: when unqualified batches are discovered, the concrete is often already poured and formed, resulting in extremely high rework costs and even leaving structural safety hazards.
For high-capacity ready mixed concrete (RMC) mixing plants, the quality confirmation cycle of nearly a month is seriously disconnected from the operational needs of continuous production.
