The American Concrete Institute Foundation announced earlier this week that its Concrete Research Council has selected six research projects to receive grants this year, aligning with ACI’s commitment to “progress in the industry by contributing financially to necessary and worthy research.”

The Projects

The following research projects will receive funding from the ACI Foundation.

Embodied Carbon in Construction Calculator (EC3) Tool, endorsed by ACI Committee 130: Sustainability of Concrete, is led by principal investigator Kathrina Simonen, Carbon Leadership Forum, University of Washington and Phil Northcott, C-Change Labs.

“The goal of the EC3 tool is to be the most available, transparent, and robustly actionable embodied carbon database for construction in North America,” according to ACI.

The American Concrete Institute Foundation announced earlier this week that its Concrete Research Council has selected six research projects to receive grants this year, aligning with ACI’s commitment to “progress in the industry by contributing financially to necessary and worthy research.”

“Further, the tool aims to include performance standards as a design criterion and this will help direct the industry to pursue performance-based design standards.”

An Innovative Approach to Concrete Confinement Reinforcement, endorsed by Joint ACI-ASCE Committee 550: Precast Concrete Structures, is led by principal investigator Ashley Thrall, University of Notre Dame, and Yahya Kurama, University of Notre Dame.

“The aim of this research is to study the behavior of seismic precast columns with ductile, high-strength (yield strength of 100 ksi or greater) steel coiled (spooled) strips as internally-placed (embedded) continuous transverse spiral confinement reinforcement,” the project description notes.

Effective Characterizations of Recycled Concrete Aggregate for Concrete Applications, endorsed by ACI Committee 555: Concrete with Recycled Materials, is led by principal investigator Jiong Hu, University of Nebraska-Lincoln, and Tara Cavalline, University of North Carolina at Charlotte.

The Foundation says that this study “intends to establish an RCA characterization protocol, provide recommendations for RCA concrete mixture designs and identify best practices for RCA to be used in concrete construction.”

Deconstruction Monitoring of a Cast-in-Place Segmental Concrete Box Girder Bridge, endorsed by ACI Committee 342: Concrete Bridge Evaluation, and 343: Concrete Bridge Design, is led by principal investigator Matthew Yarnold, Texas A&M University, and John Mander, Texas A&M University.

The goal of this study is to further the state-of-knowledge about the long-term behavior of segmental concrete box girder bridges. Research will be looking at Texas’ Sam Houston Ship Channel Bridge is in the process of being replaced after 36 years of service due to traffic volume and ship clearance demands.

Structural Response and Buckling Behavior of Slender Ultra-High-Performance Columns, endorsed by ACI Committee 239: Ultra-High-Performance Concrete, is led by principal investigator Mohamed Moustafa, University of Nevada, Reno.

“The objective of this proposed study is to test several large-scale UHPC columns with different slenderness ratio, different confinement and different cross-sections under concentric axial loading to determine the axial load capacity and ductility as it relates to crushing versus buckling,” ACI says.

“This experimental data can be immediately used to validate ACI 318 design procedures for columns and future validation/calibration of computational and constitutive models for capturing the UHPC columns structural response through failure.”

Optimization of Fiber-Reinforced Concrete Using Data Mining, endorsed by ACI Committee 544: Fiber-Reinforced Concrete, is led by principal investigator Emilio Garcia-Taengua, University of Leeds.

This project description notes that no meta-analysis of the properties of FRC has been done, and this study “aims to compile an exhaustive database with information on different FRC mixtures and their properties, and to analyze it from a data analytics perspective to develop mathematical models for their optimization.”

All information will be implemented into a software package called “OptiFRC,” which can be used to access the database compiled, to visualize and utilize the models for the optimization of FRC mix proportioning and to calibrate and use quality control charts.
