(ASCE, 2020)The influence of silica fume (SF) on the strength and water resistance of magnesium–ammonium phosphate cement (MAPC) was investigated, and the improvement mechanism was also studied by employing analysis techniques that ... -
Experimental Evaluation of Lateral Swelling Pressure of Expansive Soil Fill behind a Retaining Wall
(ASCE, 2020)Lateral swelling pressure (LSP) of expansive soils included in the total lateral pressure (TLP) often results in instability and even sliding failure of retaining walls. In this study, a modified oedometer was developed ... -
Crack Propagation Characterization of Asphalt Mixtures: Weibull Distribution and Entropy Approach
(ASCE, 2020)The semicircular bending (SCB) test is used to characterize crack propagation of asphalt mixtures at intermediate temperatures using the critical strain energy release rate or the flexibility index, known as the Louisiana ... -
Effects of Aging on Micromechanical Properties of Asphalt Binder Using AFM
(ASCE, 2020)The performance of an asphalt binder is closely related to its microstructure. Understanding the properties of asphalt binders at the nano/microscale may help to improve knowledge of their macroperformance. The emergence ... -
Experimental Investigation of Bond-Slip Performance of Reinforcement in Two Green Concretes
(ASCE, 2020)Application of green cement to replace ordinary portland cement (OPC) for concrete structures has become an active research interest. Using pull-out tests, this study explored the bond behavior of embedded rebar confined ... -
Characterization of Asphalt Mixtures Containing Double-Coated Recycled Concrete Aggregates
(ASCE, 2020)Asphalt mixtures made with recycled concrete aggregates (RCAs) derived from construction and demolition (C&D) wastes exhibits inferior properties to mixtures containing natural aggregates only. This is mainly because ... -
Effects of Modern Concrete Materials on Thermal Conductivity
(ASCE, 2020)Thermal conductivity, k, is one of the key factors that control heat transfer in concrete. This paper presents the results of an experimental study conducted to analyze the effects of modern concrete materials, such as ... -
Influence of Addition of Polycarboxylate-Based Superplasticizer on Properties of High Performance Concrete
(ASCE, 2020)Nowadays, polycarboxylate-based (PCA) superplasticizer (SP) has become the basic ingredient to prepare high-performance concrete (HPC). PCA SP with carboxylic sulfonic groups and long poly (ethylene oxide) side chain was ... -
Advanced Quality Control Models for Concrete Admixtures
(ASCE, 2020)Concrete admixtures are constantly used in construction projects, and these admixtures can be used to increase/decrease the setting time, improve workability, enhance frost and sulfate resistance, and to help control ... -
