Assessment of Crack Development in Engineered Cementitious Composites Based on Analysis of Acoustic Emissions
(American Society of Civil Engineers, 2019)In this study, acoustic emission (AE) analysis was employed to characterize the cracking behavior of various engineered cementitious composites (ECCs) containing different types of fibers. AE monitoring of prism samples ... -
Thermal Stresses of Concrete at Early Ages
(American Society of Civil Engineers, 2019)The cracking tendency of cast-in-place concrete at early ages under restrained conditions is a concern. In particular, in the building industry, in order to meet the construction speed requirements, external load (due to ... -
Effect of High-Magnesium Nickel Slag on Hydration Characteristics of Portland Cement
(American Society of Civil Engineers, 2019)This paper aims to study the effect of high-magnesium nickel slag on the hydration characteristics of portland cement paste. High-magnesium nickel slag was used as supplementary cementitious material. The compressive ... -
Flexural Performance of Ultrahigh-Performance Concrete Developed Using Local Materials
(American Society of Civil Engineers, 2019)Ultrahigh-performance concrete (UHPC) exhibits exceptional strength and durability properties that facilitate smaller, more efficient members that have longer expected lifespans compared to conventional concrete. However, ... -
Tensile Creep and Unloading Creep Recovery Testing of Dam Concrete with Fly Ash
(American Society of Civil Engineers, 2019)Gradual creep recovery manifests when a concrete specimen that has been subjected to a sustained stress is unloaded. Although creep and creep recovery are important properties of concrete, there is little research on the ... -
Corrosion Improvement of Carbon Steel in Concrete Environment through Modification of Steel Microstructure
(American Society of Civil Engineers, 2019)This study investigated the impact of the grain size of low carbon steel on its electrochemical behavior in a simulated concrete pore solution. Specimens with three grain sizes were used: as-received; coarse, with grains ... -
Effects of Cross-Sectional Size and Shape on the Longitudinal Tensile and Anchoring Properties of CFRP Cables
(American Society of Civil Engineers, 2019)Carbon fiber–reinforced polymer (CFRP) is very suitable for use as a prestressed cable and can replace conventional steel cables in cable roofs. In engineering practice, the anchoring length increases rapidly as the ... -
Tangential Adhesion Strength between Clay and Steel for Various Soil Softnesses
(American Society of Civil Engineers, 2019)To investigate the adhesion at the interface between clay and steel, a rotary shear apparatus was adopted to perform rotation shearing tests on clay materials including bentonite, kaolin and their mixture. The tangential ... -
Mechanical Behavior of Cemented Granular Aggregates under Uniaxial Compression
(American Society of Civil Engineers, 2019)Cemented granular aggregates composed of densely packed particles bound together by a matrix partially filling the interstitial pore space, connecting adjacent grains and forming cemented grain-to-grain contacts. The ... -
Experimental Study on Mechanical Properties and Failure Criteria of Self-Compacting Concrete under Biaxial Tension-Compression
(American Society of Civil Engineers, 2019)In order to explore the basic mechanical properties of self-compacting concrete, ordinary concrete, lightweight aggregate concrete, self-compacting ordinary concrete, and self-compacting lightweight aggregate concrete were ... -
Investigation on Self-Healing Behavior of Asphalt Binder Using a Six-Fraction Molecular Model
(American Society of Civil Engineers, 2019)The service life of asphalt pavement is influenced by many factors, of which the properties of asphalt binder are the most important. The self-healing properties of asphalt binder counteract the progression of fatigue and ... -
Effects of Polycarboxylate Superplasticizers with Different Functional Units on Early Hydration Behavior of Cement Paste
(American Society of Civil Engineers, 2019)Effects of polycarboxylate superplasticizers (PCEs) with different functional units on the flowability, hydration heat, and hydration products of cement paste were investigated. Two kinds of functional units, the sulfo ... -
Properties of High-Performance Self-Compacting Rubberized Concrete Exposed to High Temperatures
(American Society of Civil Engineers, 2019)Self-compacting concrete (SCC) is a unique type of concrete material where vibration or compaction is avoided by including super plasticizer in the fresh mixture to achieve homogenous compaction. SCC offers improved ... -
Small-Strain Behavior of Cement-Stabilized Recycled Concrete Aggregate in Pavement Base Layers
(American Society of Civil Engineers, 2019)A novel approach has been used to simulate the true field performance of cement-stabilized recycled concrete aggregate in pavement bases using a unique, large-scale, fully instrumented pavement model tank (PMT). Vertical ... -
