Effect of bottom ash waste on the rheology and durability of alkali activation pastes

Case Studies in Construction Materials, 2022
On a global scale, thermoelectric energy remains the main source of the energy industry. This process results in a large amount of coal waste. Among them, the bottom ash still has no suitable application in civil construction and usually is discarded in ...

Experimental and Numerical Study on Cement Paste Degradation Under External Sulfate Attack

Proceedings of the 9th International Conference on Fracture Mechanics of Concrete and Concrete Structures, 2016
External sulfate attack is one of the situations that may cause gradual but severe damage in cementitious materials, which may lead to cracking, increased permeability and strength loss. In this paper, thin-walled hollow cement paste cylinders with a wall thickness of 2.5mm were made considering the slow penetration process of sulfate ions under ...

Effects of biaxial confinement in mortars exposed to external sulfate attack [PDF]

Cement and Concrete Composites, 2019
Research on external sulfate attack (ESA) is usually performed on small scale specimens under free expanding conditions. However, most field structures cannot expand freely due to confinement induced by the ground or other elements from the structure. As a result, ESA usually develops in confined conditions.
