Abstract: Two metakaolins, with similar mineralogical composition but which vary in their surface area (11.1 versus

Abstract: Low tensile strength restricts use of natural stone in applications where tensile or flexural capacity is required, such as for long spans or thin sections (e.g., cladding, countertops, desktops). In addition, exposure to ...

Abstract: An investigation involving mechanical testing and microstructural characterization was undertaken to examine the influence of moisture state at the time of testing on the performance (i.e., strength, toughness, and failure ...

Abstract: Sulfate ions present in soil, ground water, seawater, decaying organic matter, and industrial effluents are known to have an adverse effect on long-term durability of concrete. However, ASTM test methods for predicting ...
