Development and Characterization of Ultra-High-Performance Concrete for the Rehabilitation of Navigation Lock Structures

Abstract

This report details the history of vertical lock wall repairs and the development and laboratory characterization of an ultra-high-performance concrete (UHPC) using locally sourced materials for improved durability of lock walls subjected to impact and abrasion from navigational vessels. This UHPC, referred to as Lock-Tuf, has been designed for use in a precast environment with ambient curing methods and serves as a material proof-of-concept for future lock wall rehabilitations. Mechanical properties such as unconfined compressive strength, flexural response, tensile capacity, impact resistance, and abrasion resistance have been quantified experimentally.
