Aggregates Settling Velocity-Direct In Situ Measurement
Settling velocity and size of aggregates were observed by the method where the aggregates were illuminated by light sheet (plane) and their movement and size were evaluated from image analyses of obtained images. T...

Experimental and Envoronmental Evaluation of Using Recycled Aggregates in Concrete
The article deals with using recycled aggregate in concrete. Recycled aggregate has inferior properties compared with natural aggregate. It is therefore necessary to concentrate on testing it before using in concrete. A gra...

The effect of shear rate on aggregate size distribution and structure at steady state: a comparison between a Taylor–Couette reactor to a mixing tank
used.Methods of image and fractal analyses were used to determine the aggregate size and structure, respectively. It was found that the aggregate size decreased with increasing shear rate. There was a small diff...

The effect of global velocity gradient on the character and filterability of aggregates formed during the coagulation/flocculation process
on the properties of aggregates formed during the coagulation/flocculation process. The methods of image and fractal analysis were used to determine aggregate size and structure. Predictably, it was shown that the aggr...
