AASHTO T 276-17 PDF Download

The AASHTO T 276-17 standard provides guidelines for assessing the early-age compression strength of concrete specimens and projecting their strength at later ages.

The standard outlines a procedure for creating and curing concrete specimens, followed by testing them at an early age. These specimens are then subjected to standard curing conditions, while the temperature history is recorded. This temperature data is then used to calculate a maturity index, which is indicative of strength gain in the concrete.

Additionally, the standard includes a procedure for utilizing the results of early-age compressive strength measurements to estimate the potential strength of the concrete at later ages. This information is valuable in predicting the long-term strength characteristics of the concrete, which is crucial for structural design and durability assessments.
