In karst areas, groundwater has high concentrations of carbon dioxide. It causes
decalcification of cement-based materials by reacting with calcium hydroxide and calcium …

Leaching of hydration products in cement-based materials may reduce the service life of
concrete constructions, such as radioactive waste disposal containers and hydro structures …

In circumstances with wastewater and seawater, the behavior of multi-ions including
calcium, chloride and others in concrete attracts attention. The present study investigated the …

In this work, acceleration leaching and three-point bending (TPB) tests were performed on
single-notched TPB beam specimens to explore the evolution of the fracture properties of …

Calcium leaching from cement hydrates to pore solution increases the porosity and reduces
the bonding strength of cement hydrates, accelerating the degradation of concrete. Calcium …

Calcium leaching is one of the major causes of concrete structure failure in soft water
environments. In this study, acceleration leaching and three-point bending (TPB) tests were …

Ultra-high-performance fiber-reinforced concrete (UHPFRC) is an excellent material for
harsh environments, but corrosion will change its internal microstructure and complicate the …

Leaching profoundly impacts the mechanical properties and durability of concrete. In a soft
water environment, hydration products such as calcium hydroxide in concrete will gradually …

Abstract Corrosion resistance of Mg-Al-Zn magnesium alloy (AZ41) embedded in PC paste
was investigated with 6061 aluminium alloy (AA6061) as s control. Electrochemical methods …

This work investigates the influence of calcium leaching on mechanical and physical
properties of limestone powder (LS)–cement pastes cured under different temperatures. In …
