Impact Assessment of Plastic Strips on Compressive Strength of Concrete
(American Society of Civil Engineers, 2019)This work attempts to analyze the impact of plastic strips on the compressive strength of concrete. Three sets of concrete mixes, one of conventional concrete (CC) and the other two modified concrete with plastic [polyethylene ... -
Sustainable Calcination of Magnesium Hydroxide for Magnesium Oxychloride Cement Production
(American Society of Civil Engineers, 2019)Effects of varying calcination conditions on the chemical and physical properties of magnesium oxide (MgO), an essential component of magnesium-based cement, were investigated using the more sustainable precursor material ... -
Practical Model for Predicting Internal Relative Humidity of Concrete Exposed to Drying
(American Society of Civil Engineers, 2019)This paper presents a finite-element model developed to predict concrete drying behavior and internal relative humidity with very simple inputs that are known to engineers and practitioners (concrete mix design and cement ... -
Strength Reduction Factor of Concrete with Recycled Rubber Aggregates from Tires
(American Society of Civil Engineers, 2019)Recycling of waste tire rubber is a significant environmental problem due to the huge number of waste tires needing disposal. A promising alternative to methodologies usually used for this aim is the use of tire rubber in ... -
Effects of Aging and Rejuvenation on Surface-Free Energy Measurements and Adhesion of Asphalt Mixtures
(American Society of Civil Engineers, 2019)This paper presents the results of a study that was conducted to understand the impacts of aging and rejuvenation on fundamental properties of asphalt binders. A Performance Grade (PG) 64-22 binder was aged to simulate the ... -
Influence of Poker Vibration on Aggregate Settlement in Fresh Concrete with Variable Rheological Properties
(American Society of Civil Engineers, 2019)Internal vibration is adopted worldwide for consolidating fresh concretes in field construction. Improper manual operation of the vibration process can easily induce segregation and bleeding of fresh concrete and subsequent ... -
Correlation of DSR Results and FTIR’s Carbonyl and Sulfoxide Indexes: Effect of Aging Temperature on Asphalt Rheology
(American Society of Civil Engineers, 2019)This paper investigates the effects of different aging temperatures on the performance of asphalt binders through a comprehensive experimental procedure. Two kinds of asphalt binders with the same 70/100 penetration grade ... -
Effects of Alumina as an Effective Constituent of Metakaolin on Properties of Magnesium Phosphate Cements
(American Society of Civil Engineers, 2019)The main interest of this research investigation is to explore the effects of the Al2O3 proportion present in metakaolin (MK) on the mechanical properties of magnesium phosphate cement (MPC). Different contents of MK and ... -
Pore Structure Models to Predict Hydraulic Conductivity of Recycled Asphalt Pavements
(American Society of Civil Engineers, 2019)Recycled asphalt pavement (RAP) is increasingly being used due to the economic savings and environmental benefits. RAP contains removed or reprocessed asphalt binder and aggregates instead of virgin material. In order to ... -
Effect of pH and Subgrade Type on Trace-Metal Leaching from Steel-Slag Embankments into Groundwater
(American Society of Civil Engineers, 2019)An experimental research program was carried out to evaluate the environmental impacts of embankments constructed with steel slag on groundwater. A series of sequential water leach tests and sequential column leach tests ... -
Volumetric Properties of Concrete under True Triaxial Dynamic Compressive Loadings
(American Society of Civil Engineers, 2019)Almost all of the available test data for pressure–volumetric strain curves [equations of state (EoS)] of concrete are based on static triaxial tests and one-dimensional impact tests, for example, the flyer-plate impact ... -
Assessing Hydrated Cement Paste Properties Using Experimentally Informed Discrete Models
(American Society of Civil Engineers, 2019)Properties of concrete are, to a large extent, dependent on the properties of its binding constituent, hydrated cement paste. Therefore, knowledge of properties of hydrated cement paste is crucial for predicting concrete ... -
