Sulfate soundness test gave misleading results in judgement of the unbound state frost durability due to the highly disruptive physicochemical effect of the method on the recycled concrete aggregates, regardless of the air void characteristics of the materials.
The volume of air voids, equivalent diameter and roundness were used to characterize the void characteristic of the asphalt mixtures with different angular aggregates by the analysis of Image-Pro Plus (IPP).
By using the mesoscopic void characteristics of mineral powder fillers as intermediaries based on the proportions of fixed and free asphalts, we can identify the effects of these characteristics on the low-temperature cohesive strength of asphalt mortars.
The mesoscopic void characteristics of mineral powder fillers can result from the combined effects of mesoscopic grading, length-to-diameter ratio, specific surface area and circular degree, among others.
The air void characteristics of mixtures were also investigated by mercury intrusion porosimetry (MIP), linear transverse method, and scanning electron microscope (SEM) images.
So while Anteby's style reads as figurative, it's actually coming from a place of deep meditation and for lack of a better word a "void," which is characteristic of wu wei.
The air void distribution characteristics of CIR specimens were analyzed based on the concept of air void gradation.
Experiments were conducted to investigate the unsteady state void fraction characteristics of inverse fluidized bed (IFB) subjected to step change in liquid velocity.
The lath-like nature of this assemblage (shards separated by void space) is characteristic of chattering, an artifact produced during microtome sample preparation and, in this respect, is similar to samples observed from the STARDUST mission (Zolensky et al. 2006).
Next, core samples at representative density point were drilled and of which the voids distribution characteristic on sectional image of core sample was analyzed by image processing technology, and further on, the evaluation index of void distribution uniformity was put forward.
Open image in new window Figure 16 SEM fractograph features of specimen B1 (low temperature) with voids and dimples characteristic of ductile fracture.
