Calcium-based binders, such as ordinary Portland cement (OPC) and lime (CaO), are the
most common artificial cementitious materials used worldwide for concrete and soil …

External sulfate attack (ESA) of cementitious materials has been studied worldwide for a
very long time. This physical/chemical interaction between sulfate ions and the cement …

Drying–wetting cycles (DWC) are suspected of influencing the performance of concrete
under sulfate attack, but the nature and extent of this influence are still unclear. Therefore …

Concrete constructions used in harsh marine environments are commonly destroyed by
sulfate ions. In this paper, by modeling aggregates as random convex polygons, to analyze …

Internal sulfate attack (ISA) occurs in cement composites due to the presence of mineral
sulfide in aggregates, such as pyrite (FeS 2). The oxidation of the pyrite releases sulfate …

The mine water environment in underground reservoirs poses great threat to the durability of
artificial concrete dams, mainly due to the coupled sulfate and drying-wetting cycles. As a …

The propagation of ultrasonic wave in cement paste is closely related to its physical
properties, and therefore shows a potential application in fields of online monitoring of …

Sulphate corrosion of concrete is a complex chemical and physical process that leads to the
destruction of construction elements. Degradation of concrete results from the transportation …

A novel horizontal omnidirectional piezoelectric ultrasonic transducer suitable for real-time
monitoring of hardened cement paste was developed. The ultrasonic technique was …

Underground cavities induced by damaged slurry walls or soil erosion in urban areas
require suitable repair materials and methods. The objective of this study is to evaluate the …
