In-Plane Modes of Fracture and Effective Parameters of Self-Consolidating Concrete
(American Society of Civil Engineers, 2019)In this paper, Mode I and Mode II fracture energies of self-consolidating concrete (SCC) are examined. Two shapes of Mode II specimens are used, and the specimens are made from mixtures with three different water-to-cement ... -
Detection of Thaumasite Formation Using Differential Scanning Calorimetry
(American Society of Civil Engineers, 2019)Thaumasite sulfate attack was studied on mortars containing portland-limestone cements and various supplementary cementing materials. The resistance of the mortar mixtures against deterioration was quantified by measuring ... -
Hydration, Pore Solution, and Porosity of Cementitious Pastes Made with Seawater
(American Society of Civil Engineers, 2019)Unreinforced concrete or concrete reinforced with noncorrosive reinforcement could potentially be mixed with seawater in locations where potable water is scarce. A fundamental understanding of the properties of concrete ... -
Effect of RAP Source on Cracking Resistance of Asphalt Mixtures with High RAP Contents
