Abstract:
Traditional methods of construction for reinforced concrete columns utilize longitudinal steel bars and transverse ties. Field experience has shown that such a transverse reinforcement method is labor-intensive, time-consuming, and prone to inconsistencies in quality. Welded wire reinforcement (WWR) offers a prefabricated alternative, forming a closed cage that simplifies installation and speeds up the fabrication process. This study investigates the potential of using WWR as a replacement for conventional ties in reinforced concrete columns in pure compression. To achieve this objective, eigh

Abstract:
The objective of this study is to determine experimentally and analytically the magnitude of the strength enhancement of concrete confined by lateral ties. Sixty-five reinforced concrete columns with a 200 mm square cross section were tested. Experimental parameters include the compressive strength of concrete; the volumetric ratio, strength, and confinement type of rectilinear ties; and the distribution of longitudinal reinforcement bars. The confinement effects are explained by utilizing an effectively confined distance ratio. Tie stress caused by lateral concrete pressure is presented as a

Abstract:
Sustainable development is a major issue confronting society today. Cement, a major constituent of concrete, is a key component of any infrastructure development. The major drawback of cement production is that it involves the emission of CO2, the predominant greenhouse gas causing global warming. The development of geopolymers has resulted in a decrease in cement production, as well as a reduction in CO2 emissions. During mass concrete production in the construction of very large structures, interfaces/joints are formed, which are potential failure sites of crack formation. Concrete may inter

These strapping ties are compared against traditional ties by a three-dimensional micro-numerical model and the experimental behavior of short tie columns.

Abstract:
As an important element in track, pre-stressed concrete railroad ties in the high-speed rail industry must meet the safety and performance specifications of high-speed trains. Systematic destructive and non-destructive evaluation of existing concrete ties can lead to a better understanding of the effect of prestressed concrete tie material design on performance and failure within their service life. It has been evident that environmental and climate conditions also have a significant impact on concrete railroad ties, causing various forms of deterioration such as abrasion and freeze-thaw damag

Abstract:
During January 2013, concrete railroad ties were cast at a tie manufacturing plant with fifteen different reinforcement types that are widely employed in manufacturing of railroad ties worldwide. Among these reinforcements; there were 12 different 5.32 mm diameter wires with various surface indent geometries, two different 7-wire strands with 3/8-inch diameter, and one 3-wire strand with 5/16-inch diameter. Four concrete ties were cast for each reinforcement type for a total of 60 concrete ties. Among the four ties for each reinforcement type, two ties were installed in track and subjected to

Abstract:
This report investigated pathways to reduce concrete curing time while maintaining mechanical and durability performance. Among several options such as admixtures, supplementary cementitious materials, and low water-to-cement ratio, researchers explored two mix designs in a field demonstration project. For Stage I of the project, a low water-to-cement ratio concrete mixture was used. For Stage II, the use of calcium-silicate-hydrate (C-S-H) based seeds was explored. Concrete laboratory mixtures containing C-S-H seeds X1 and X2 exhibited increased early-age strength and reduced permeability. Ba

Abstract:
High-volume fly ash concrete (HVFAC) has improved durability and sustainability properties at a lower cost than conventional concrete, but its early-age properties like strength gain, setting time, and air entrainment can present challenges for application to concrete pavements. This research report helps with the implementation of HVFAC for pavement applications by providing guidelines for HVFAC mix design, testing protocols, and new tools for better quality control of HVFAC properties. Calorimeter tests were performed to evaluate the effects of fly ash sources, cement–fly ash interactions, c

Abstract:
High-volume fly ash concrete (HVFAC) is more cost-efficient, sustainable, and durable than conventional concrete. This report presents a state-of-the-art review of HVFAC properties and different fly ash characterization methods. The main challenges identified for HVFAC for pavements are its early-age properties such as air entrainment, setting time, and strength gain, which are the focus of this research. Five fly ash sources in Illinois have been repeatedly characterized through x-ray diffraction, x-ray fluorescence, and laser diffraction over time. The fly ash oxide compositions from the sam

Abstract:
In the fast-paced and time-sensitive fields of construction and concrete production, real-time monitoring of concrete strength is crucial. Traditional testing methods, such as hydraulic compression (ASTM C 39) and maturity methods (ASTM C 1074), are often laborious and challenging to implement on-site. Building on prior research (SPR 4210 and SPR 4513), we have advanced the electromechanical impedance (EMI) technique for in-situ concrete strength monitoring, crucial for determining safe traffic opening times. These projects have made significant strides in technology, including the development

Abstract:
Ultra-high-performance concrete (UHPC) represents the next generation of concrete, with a strength 3-4 times greater than traditional concrete (100-120 MPa as opposed to 30-40 MPa). However, most of the commercial UHPC mixes are proprietary and expensive. In this project, we document the development of nonproprietary, cost-effective UHPC mixes primarily using locally sourced or pre-qualified materials in Illinois. The research utilizes the modified Anderson and Andreasen packing model to establish a new parameter: “packing factor” that has a significant influence on the design and performance

Abstract:
In additive construction, ambitious goals to fabricate a concrete building in less than 24 hours are attempted. In the field, this goal relies on a metric of print time to make this conclusion, which excludes rest time and delays. The task to complete a building in 24 hours was put to the test with the first attempt at a fully continuous print of a structurally reinforced additively constructed concrete (ACC) building. A time series analysis was performed during the construction of a 512 ft2 (16’x32’x9.25’) building to explore the effect of delays on the completion time. This analysis included

Abstract:
The need to conduct complex operations over time results in U.S. forces remaining in deployed locations for long periods. In such cases, more sustainable facilities are required to better accommodate and protect forward deployed forces. Current efforts to develop safer, more sustainable operating facilities for contingency bases involve construction activities that redesign the types and characteris-tics of the structures constructed, reduce the resources required to build, and reduce resources needed to operate and maintain the com-pleted facilities.
