those of the polygonal aggregate; (2) The hydration products in the transition zone of the interface of different shapes of aggregates are almost the same, indicating that the influence of the shape of aggregates on the performance of concrete is mainly due to its own geometric characteristics....
In addition to morphology, thermo-mechanical and acoustic properties, their environmental impact were evaluated. The results show, that plastic waste has a positive effect by decreasing the density. Moreover, the concrete with 75% of PE aggregate presents the lowest dynamic elastic modulus; which ...
1.The influences of rough aggregate on mechanical properties of concrete;浅谈粗糙集料质量对混凝土力学性能的影响 4)coarse aggregate粗聚集体,粗集料 5)coarse aggregate粗集料;粗骨料 6)coarse aggregate morphology粗集料形态 1.The coarse aggregate morphology quantified by angularity and surface texture prope...
On the other hand, the substitution of NS with GF may impact the property of the concrete, which eventually further impacts its structural performance [30,31]. Physical properties of aggregate such as shape, texture, and grading have significant effects on the performance of fresh and hardened ...
Rheo-morphological investigation of Reynolds dilatancy and its effect on pumpability of self-consolidating concrete New methodology to evaluate the morphology of coarse aggregate using 3D image analysis was also proposed. The Reynolds dilatancy values of the investigated ... OYA Hosseinpoor - 《Cement ...
Evaluation of Aggregate Size and Shape by Means of Segmentation Techniques and Aggregate Image Processing Algorithms Portable image analysis system for characterizing aggregate morphology. Can cognitive inferences be made from aggregate traffic flow data?
The fractal dimension of concrete can be used to characterize the complexity of the spatial distribution morphology of the cement matrix pores; that is, the larger the fractal dimension of the pore volume, the more complex the spatial distribution morphology of the pores and the greater their spac...
Particle size distribution and shape properties are known to significantly influence the mechanical properties, e.g. strength, permanent deformation and packing density, of aggregates. Image analysis is a more efficient and accurate approach to quantify
Moreover, the extremely irregular shape of the aggregates leads to a difficult compaction of concrete, which leads inevitably to an increase in the occluded air [35]. This decrease in density, however, involves the reduction of the compressive strength [74], as explained below. It is also ...
Therefore, the water absorption of recycled concrete aggregate (RCA) is 30–200% higher than that of the NA [7]. Additionally, the crushing method significantly affects the shape and texture of the RCA, and the crushing process may also produce new micro cracks in RCA. It is widely ...
