Which aspect is NOT a component of concrete quality control?

• A. Moisture deformation on sand
• B. Slump testing
• C. Material costs
• D. Air meter analysis

Answer: (C)

Concrete quality control involves various testing and evaluation methods to ensure that the concrete produced meets the required specifications for strength, durability, and consistency. Key components of quality control include various testing procedures that assess the physical properties of the concrete mix. Moisture deformation on sand is crucial because it deals with the water content in the aggregates, which directly affects the workability and strength of the concrete. Slump testing evaluates the consistency and flow of the concrete, indicating its workability. Air meter analysis is important as it measures the volume of air voids in the concrete, which impacts durability and resistance to freeze-thaw cycles. While material costs are certainly a consideration in the overall project budget and may influence decisions about material selection, they are not a direct component of concrete quality control processes. Quality control focuses on the actual performance characteristics of the materials rather than the expense associated with them, making material costs an outlier in this context.
