measured by inserting a thermometer into the top six inches of

,concrete.( T or F) - ✔✔ANSWER✔✔-False (does not specify
aggregate size)

ASTM C1064 states the container used to measure
temperature of concrete must be large enough to provide at
least 5 inches of concrete. ( T or F) - ✔✔ANSWER✔✔-False (
