In the context of ASTM C1064, which covers the temperature of freshly mixed hydraulic-cement concrete, the standard does not specify a maximum temperature that must be adhered to for all situations. Instead, the standard addresses the measurement of the temperature of freshly mixed concrete and provides guidelines for how to obtain accurate temperature readings.

While it is essential for concrete to be within certain temperature ranges during mixing and placement to ensure proper hydration and workability, any limitations on maximum temperature tend to arise from project-specific guidelines or requirements rather than being universally dictated by ASTM C1064. Thus, the statement about a maximum temperature being specified in the standard itself is not accurate, leading to the conclusion that it is false. This allows for the flexibility needed to accommodate various mixes, environmental conditions, and project specifications that may dictate particular temperature controls for specific applications.
