Synthesis and Reaction Mechanism of an Alkali-Activated Metakaolin-Slag Composite System at Room Temperature
(American Society of Civil Engineers, 2019)Synthesis of geopolymer using metakaolin (MK) usually requires a relatively high curing temperature, which limits the application of MK-based geopolymers in the practice of civil engineering. With the goal of developing a ... -
Experimental and Theoretical Studies on Effect of Height-to-Diameter Ratios on Failure Forms and Mechanical Characteristics of Foamed Concrete
(American Society of Civil Engineers, 2019)The response of concrete under uniaxial loading is dependent on its density and the height-to-diameter (H∶D) ratio of the specimen, and this phenomenon has received wide attention in research on normal concrete. However, ... -
Comparing Laboratory Conditioning Protocols to Longer-Term Aging of Asphalt Mixtures in the Southeast United States
(American Society of Civil Engineers, 2019)This paper uses mixture tests on cores from a full-scale and untrafficked test section to evaluate mixture conditioning protocols intended to simulate asphalt mixture damage experienced from non–load-associated environmental ... -
Influence of Types of Grouting Materials on Compressive Strength and Crack Behavior of Rocklike Specimens with Single Grout-Infilled Flaw under Axial Loads
(American Society of Civil Engineers, 2019)Rocklike specimens with a grout-infilled flaw having different inclination angles were prepared for uniaxial compressive tests to study the effect of types of grouting materials and flaw inclination angle on the compressive ... -
