Alkali-silica reaction (ASR) and delayed ettringite formation (DEF) are expansive reactions that can lead to the premature deterioration of concrete structures. Both have been implicated in the deterioration of numerous ...

Current Texas Department of Transportation (TxDOT) procedures for evaluating coarse aggregate for portland cement concrete (PCC) have been in place for over 39 years. Item 421 in the TxDOT "Standard Specifications for ...

Concrete overlays have been a rehabilitation method for many years. It has been extensively utilized and studied in other states, but Texas is still at an initial stage of fully implementing the method. The large volume ...

Ultra-High Performance Concrete (UHPC) is an emerging material technology that exhibits a combination of high compressive strength, high tensile strength, high toughness and ductility, and improved durability when compared ...

Electrical conductivity (or resistivity) of cementitious materials is considered to be a fundamental property and is commonly measured using nondestructive and noninvasive testing techniques. Therefore, electrical measurements ...

The coefficient of thermal expansion (CTE) is one of the major factors responsible for distresses in concrete pavements and structures. Continuously reinforced concrete pavements (CRCPs) in particular are highly susceptible ...

Crucial part of the estimation of construction waste (CW) is a reliable quantification of the amounts of materials needed for building construction. In this research the use of Building Information Modeling (BIM) is proposed ...

This thesis presents an experimental study on the horizontal shear strength of reinforced concrete slabs and beams with unreinforced concrete-to-concrete interfaces. Current design provisions for new construction and repair ...

In order to improve the fire safety and at the same time to provide more economical design of composite floors in fire, it is important to understand the behavior of these systems under fire exposure. An important step ...

Highway air pollution is a significant environmental threat that has staggering implications for human health worldwide. Photocatalytic materials have the potential to reduce air pollution levels near major highways using ...
