While the process gives concrete its strength, spaces between the hydrates create an extensive pore network in the cement paste.

Cracking occurs due to two mechanisms: differential drying shrinkage between the core and the surface; strain incompatibilities between cement paste (subjected to drying shrinkage) and stiff aggregates (Meschke et al., 2018).
Cement materials, including cement paste, mortar and concrete, are the most widely manufactured materials in the world.
When the critical stress at which the cement paste transforms from elastic to viscous state, the Bingham model is suitable for the paste research in this study [26].
The FE-SEM was also used to analyse the hydration process of the periclase in cement paste. For BSEM image analysis, the dried slice samples of the cement clinker and the hydrated cement pastes were impregnated with epoxy resin in order to block in the hole.
The cement paste specimens were separated into four groups representing different mixing method of mineral admixtures: add single fly ash (including A1-A3 group), add single slag (including B1-B3group), add both fly ash and slag (including C1-C3 group), and control group (including J group).
D was calculated as the area under the load-deflection curve after the maximum load, and it consists of two components: the contribution from the cement paste (D1) and the contribution from the MWCNT (D2).
As a fluid loss additive of oil well cement with good performance, it should be satisfied with two conditions: having no effect on the strength development of cement paste and having a positive influence on the sedimentation stability of the cement slurry.
Figure 1 shows a typical heat flow per cement mass of a cement paste, measured by isothermal calorimetry.
It can incorporate relatively large amounts of Na+ and K+ which displace Ca2+ in the lattice, and this can affect the pore solution chemistry of cement paste which contains metakaolin.
A portion of the cement paste of a conventional concrete (10-30 vol%) is replaced with an equal volume of foamed styrene/polystyrene resin.
