AASHTO T276
Full Name
AASHTO T276 – Standard Method of Test for Measuring Early-Age Compression Strength and Projecting Later-Age Strength
Scope
This test method covers a procedure for making and curing concrete specimens and for testing them at an early age.
The specimens are stored under standard curing conditions and the measured temperature history is used to compute a maturity index that is related to strength gain.
This test method also covers a procedure for using the results of early-age compressive-strength tests to project the potential strength of concrete at later ages.
