Sentence examples for in paste volume from inspiring English sources

Table 5, containing the mixes, shows that the adopted approach leads to an increase in paste volume with a slight decrease in density.

The use of VMA is associated with reduction in paste volume which is believed to be detrimental to the LWSCC mixture stability, passing ability, filling ability and segregation resistance.

In order to verify if the accentuation is due to the continuous water absorption by recycled aggregates and not to the increase in paste volume, the loss in workability of two cement pastes corresponding to NAC and RAC100 was followed during 2 h. Figure 7 shows the changes of paste slumps with time where it can be seen that the two pastes undergo the same kinetic of loss.

Pressure (kPa), under which the cement paste starts flowing, the average cement paste flow rate (cm/s), elastic deformation and the increase in cement paste volume due to redistribution of solid phase particles were established in experimental tests of Portland cement pastes with different W/C ratio, Portland cement pastes with SiO2 microparticle suspension and quartz sand additive.

Furthermore, this article highlights that at low confinement, the concrete strength significantly increases with an increase in cement paste volume.

The results indicate that the flow properties of SCC increase with an increase in the paste volume.

In the paper the methodology and results of investigation of the influence of temperature and time on the rheological properties of cement paste and different in cement paste volume fresh self compacting concrete are presented and discussed.

The increase in cement paste volume during the flowing has been determined by specially developed equipment and the investigation methodology was proposed.

The increase of porosity with replacement ratio is mainly due to the high porosity of recycled aggregates, to the increase in the paste volume and to the poor interface paste-aggregates as well as to the increase in air content (cf. Fig. 9).

Indeed, at a constant W/C ratio, when the concentration of cement increases in the paste volume (i.e. the reduction of effective water to cement ratio), the compressive strength is maintained constant despite the increase in air content (Table 5).

Volume contraction due to drying and autogenous shrinkage in the cement paste; Volume contraction in cooling phase of the hardened concrete; Presence of restraints that limit the contraction of concrete.
