AASHTO R 81-17 PDF Download

AASHTO R 81-17 is a standard practice that focuses on the static segregation of hardened self-consolidating concrete (SCC) cylinders. The purpose of this standard is to provide procedures for determining the stability of SCC through the evaluation of its static segregation resistance.

The standard outlines specific testing procedures to be followed in order to obtain accurate and reliable results. These procedures involve the use of hardened test specimens, which are subjected to various tests to determine the extent of static segregation within the SCC. The goal of these tests is to assess the stability of the SCC and its ability to maintain a homogeneous and well-distributed mix throughout the hardened state.
