Guide on 3-D Printed Molds for Precast Concrete
Guide on 3-D Printed Molds for Precast Concrete (PCI-ORNL-01-21)

This publication provides essential background information and guidance on using three-dimensional (3-D) printed molds to fabricate precast concrete. Their advantages, requirements, applicability, and implementation are discussed, and a detailed case study shows how 3-D printed molds were used to produce precast concrete façade components for an actual construction project. The guide is an outcome of a... Details

Guidelines For Use Of Self-Consolidating Concrete
Guidelines For The Use Of Self-Consolidating Concrete In Precast/Prestressed Concrete, 2nd Edition (TR-6-15)

The guidelines have been updated to incorporate developments that have taken place since 2003. The term “interim” has been removed from the title in recognition that these guidelines represent current recommended practice of using SCC in the precast/prestressed concrete industry. These guidelines address the use of SCC in precast, prestressed concrete manufacturing... Details

Guidelines for the Use of UHPC in Precast Concrete
Guidelines for the Use of Ultra-High-Performance Concrete (UHPC) in Precast and Prestressed Concrete HARD COPY (TR-9-22)

Ultra-high-performance concrete (UHPC) is a high-strength, high-durability composite material consisting of a cementitious matrix with high-performance-fiber reinforcement. This publication provides a practical guide for the development and qualification of UHPC mixtures based on locally available materials. It presents ... Details

CB-02 Lateral Stability Precast Concrete Bridge Girders
Recommended Practice for Lateral Stability of Precast, Prestressed Concrete Bridge Girders (CB-02-16)

This is a new comprehensive methodology to analyze the lateral stability of long slender bridge girders. Technology has enabled the manufacture of increasingly longer girders. Slender girders present a lateral stability concern. Each stage of a girder’s transition from the casting bed to its final location in the bridge is considered. These conditions include when...
