Development of a full-Scale approach to predict overlay reflective crack [PDF]
International Journal of Pavement Engineering, 25(1), 2310095
(2024)Resurfacing a moderately deteriorated Portland cement concrete (PCC) pavement with asphalt concrete (AC) layers is considered an efficient rehabilitation practice. However, reflective cracks may develop shortly after resurfacing because of discontinuities (e.g. joints and cracks) in existing PCC pavement.

Silica-coated admixtures of bismuth and gadolinium oxides for 3D printed concrete applications: Rheology, hydration, strength, microstructure, and radiation shielding perspective [PDF]
Construction and Building Materials, Volume 470, 4 April 2025,
140563This study examines the impact of replacing up to 5 vol% of Portland cement (PC) with both pristine Bi2O3/Gd2O3 (BG) and silica-coated BG particles. Two different types of silica coatings, each with varying synthesis methods, were applied to coat the BG structures, and their impact on the fresh, hardened, microstructure and radiation-shielding ...

Ultrasonic monitoring of carbonation in Portland cements [PDF]
arXivChemical reactions resulting from the ingress of carbonates into the cement matrix modify the properties of its pore solution, as well as its pore distribution and size. These changes lead to corrosion of the steel in reinforced concrete. The nature of conventional testing for the estimation of carbonation in cement-based materials is time-consuming ...

Yielding and flow of foamed metakaolin pastes [PDF]
arXiv, 2015 Metakaolin is a broadly used industrial raw material, with applications in the production of ceramics and geopolymers, and the partial replacement of Portland cement. The early stages of the manufacturing of some of these materials require the preparation and processing of a foamed metakaolin-based slurry.

Dynamics, Structure and Glass Formation of Calcium Aluminate Liquids [PDF]
arXiv, 2017 Crystalline calcium-aluminates include the phases essential in the setting of Portland cements developed over the last century. It is only within recent decades, however, that calcium-aluminate melts and glasses have begun to attract attention, bringing new functionalities in photonic and electronic applications.
