What aspects should be inspected during field concrete placement?

During field concrete placement, it is essential to inspect aspects that directly affect the performance and quality of the concrete. Consistency refers to the workability of the concrete mix, which is crucial for ensuring that the concrete can be easily placed and properly filled into forms without leaving voids. Temperature is also important, as it can influence the setting time of concrete and the rate of hydration, which are critical factors in achieving the desired strength and durability. Proper consolidation involves ensuring that the concrete is adequately vibrated or compacted to eliminate air pockets and achieve a dense, homogeneous mix, which is fundamental for structural integrity and long-term performance.

Other options may reference important parameters, but they do not encompass the critical factors necessary during the actual field placement process, which primarily focuses on how the concrete behaves when it is being poured and compacted. Ensuring proper consistency, temperature control, and effective consolidation directly contributes to the successful placement of concrete.
