Numerical analysis of calcium leaching on the durability of dam concrete

Concrete dams are subjected to soft water penetration of a high water head during their long service lives. Degradation due to calcium leaching will decrease the durability of the concrete and affect dam safety. The long-term performance of concrete dams due to calcium leaching should be evaluated and predicted accurately to complete the...

Effect of graphite on hot metal desulphurisation

During the magnesium-lime co-injection process for hot metal desulphurisation, graphite can precipitate as a result of carbon oversaturation. The formed graphite is known to form a layer between the slag and the hot metal. This potentially blocks the sulphides, that are formed during the desulphurisation process, to reach the slag phase thus...

Improvement of erodibility of a sand (sandy soils) treated by microbially induced urea-based carbonate precipitation: (Abstract)

Alloy by design: A materials genome approach to advanced high strength stainless steels for low and high temperature applications

We report a computational 'alloy by design' approach which can significantly accelerate the design process and substantially reduce the development costs. This approach allows simultaneously optimization of alloy composition and heat treatment parameters based on the integration of thermodynamic, thermo-kinetics and a genetic algorithm...

Increased sustainability of softening by producing pure calcite pellets for reuse

About 50% of the drinking water in the Netherlands is centrally softened by the drinking water companies in a process known as pellet softening. In this process a base and seeding material are mixed in an upflow reactor, where subsequently CaCO3 precipitates on a seed core as pellets. The seeding material is usually sand, but recently CaCO3 was...

Self healing by Cu precipitation in deformed Fe-Cu-B-N-C

Steels are among the most widely used construction materials as their mechanical properties can be tuned over a very wide range of desired combinations of strength formability and other properties. However, when exposed for long times to high temperatures steel components can exhibit premature and low-ductility creep fracture, which arises from...
