- Q1
How does the strength and dimensional accuracy of objects printed using selective cement activation change as the amount of water applied increases?
the strength increases and the dimensional accuracy decreases
the strength and dimensional accuracy remain unaltered
the strength decreases and the dimensional accuracy increases
300s - Q2
Which of the following materials is used in the Shotcrete 3D printing process?
polymer
concrete
clay
300s - Q3
Which tungsten additive manufacturing process yields the better spatial resolution?
PBF-EB/M
DED-EB
PBF-LB/M
300s - Q4
What distinguishes the analysis using the wavelet transform from that using the short-time Fourier transform?
With the selected parameters, the wavelet transform better represents the short-term oscillatory processes.
The short-time Fourier transform has better temporal resolution
No difference

Which of the following materials are used as supplementary cementitious materials (SCM) to reduce the cement content of concrete?
calcinated clay
fired sulphur
ionised sodium
300s - Q6

Relativistic electrons
High-energy ions
Annealing in a deuterium atmosphere
300s - Q7
Which of the following options does not affect the time and energy required for diffusion welding?
The color of the operator's gloves
The geometric, physical, and chemical properties of the welded parts' surfaces
The temperature and pressure during diffusion welding
300s - Q8
Which material-specific phenomena need to be taken into account in the long-term monitoring of reinforced concrete structures?
Attenuation, Shrinkage, and Corrosion
Frost Attack, Corrosion, and Sauction
Frost Attack, Carbonation, and Corrosion
300s - Q9
What are the main reaction products formed during the wet carbonation of hydrated cement fines?
Unreacted clinker and hydrate phases
Gypsum and Monocarbonate (AFm phase)
CaCO3 and Al-Si-Gel
300s - Q10
What is the advantage of dynamic cross-flow filtration over conventional separation methods for extracting pore solution from cement paste?
Easy to implement
Low material consumption
Continuous extraction of filtrate
300s - Q11
Why do we use confocal microscopy?
to detect aggregates
to detect air-voids

300s - Q12
Which thermodynamic database is commonly used to modelcementitious systems?
CEMmod2020
CEMDATA18
ThermoCEM
300s - Q13
What is the most significant risk posed by boiling in the cooling channels of plasma-facing components?
Boiling can lead to localized overheating, which can damage the component
Boiling causes vapor pockets, increasing the risk of thermal fatigue
Boiling can lead to flow blockages, reducing pumping efficiency
Boiling can cause pressure buildup, leading to channel rupture
