Investigation of the Performance of Self-Consolidating Concrete in Drilled Shafts. Final Report

摘要

This report summarizes the New Hampshire Department of Transportations (NHDOT) investigation of the performance of self-consolidating concrete (SCC) when used in drilled shaft applications. SCC and conventional concrete (CC) piles were evaluated side-by-side for infilling properties, air content, and segregation. The investigation was undertaken because the method of construction on this highway project exposed several feet of the shafts after they were poured affording a unique opportunity to observe the infilling properties of the two mixes. The NHDOT concluded that for the mixes used, there was no significant difference in performance.
