AASHTO T 178-15 (2019) PDF Download

The AASHTO T 178-15 (2019) standard is a test method for determining the portland-cement content of a sample of hardened hydraulic-cement concrete. The purpose of this test is to assess the cement content, which is essential for evaluating the quality and performance of the concrete.

The standard provides a systematic procedure for conducting the test. It involves extracting a core sample from the hardened concrete structure and preparing it for testing. The extraction and preparation process must be performed carefully to ensure accurate results. Once the sample is ready, the cement content is determined by using a chemical method or by analyzing the density of the sample.

Accurate assessment of the cement content is crucial for understanding the concrete's strength, durability, and other properties. This information is valuable for quality control purposes, as well as for assessing the performance of the concrete in different applications. The AASHTO T 178-15 (2019) standard defines the specific protocol for conducting this test, ensuring consistency and reliability in cement content determination for hardened Portland cement concrete.
