Improving the Carbonation of Reactive MgO Cement Concrete via the Use of NaHCO3 and NaCl
(American Society of Civil Engineers, 2018)The performance of reactive MgO cement (RMC)-based concrete formulations is determined by the carbonation process, which is hindered by the inadequate CO2 dissolution in the pore solution. This study addresses the improvement ... -
Effect of GGBS on Water Absorption Capacity and Stability of Superabsorbent Polymers Partially Crosslinked with Alkalis
(American Society of Civil Engineers, 2018)In an attempt to improve the sustainability of construction and reduce portland cement (PC) consumption, the use of supplementary cementitious materials (SCMs), such as ground granulated blast-furnace slag (GGBS), has ... -
Experimental Validation of Relaxation Prediction Models in Concrete
(American Society of Civil Engineers, 2018)Concrete undergoing volumetric changes is likely to be met with sustained restraint. This restraint leads to stresses which are reduced by tensile relaxation, in turn enabling the mitigation of cracks. Although creep and ... -
Characterization of Crack Growth Rate of Sulfur-Extended Asphalt Mixtures Using Cyclic Semicircular Bending Test
(American Society of Civil Engineers, 2018)Characterizing crack propagation of asphalt mixtures is helpful for optimizing mixture design and predicting cracking performance of asphalt pavements. This paper explores a new method based on the cyclic semicircular ... -

Prediction of Concrete Coefficient of Thermal Expansion by Effective Self-Consistent Method Considering Coarse Aggregate Shape
(American Society of Civil Engineers, 2018)Thermal cracking is a perennial concern for large-volume concrete projects; for instance, dams and foundations. The concrete coefficient of thermal expansion (CTE) is well recognized as a key parameter influencing thermal ... -
CSA-Treated Sand for Geotechnical Application: Microstructure Analysis and Rapid Strength Development
(American Society of Civil Engineers, 2018)This paper studies the effectiveness of calcium sulfoaluminate (CSA), which has a much lower carbon footprint than conventional ordinary portland cement (OPC), in geotechnical applications which use high water:cement ratios. ... -
Continuous Compaction Control Technology for Granite Residual Subgrade Compaction
(American Society of Civil Engineers, 2018)The implementation of roller-integrated continuous compaction control (CCC) technology on three types of granite residual subgrade (GRS) was evaluated in this work; the three types of GRS are cement-treated GRS, GRS with ... -
Effect of Asphalt Binder Grade and Source on the Extent of Rheological Changes in Rejuvenated Binders
(American Society of Civil Engineers, 2018)Rejuvenators are primarily added to aged binders to restore their properties by lowering their stiffness and improving their stress relaxation. The type of interaction that takes place between the rejuvenator and the binder ... -
Degradation of Creep Behaviors of Basalt Fiber–Reinforced Polymer Tendons in Salt Solution
(American Society of Civil Engineers, 2018)This study investigates the creep behaviors of basalt fiber–einforced polymer (BFRP) tendons as a prestressing material in salt solution. Static tensile tests and creep tests were conducted on the BFRP tendons after aging ... -
