Aggregate size and shape measurements are increasingly becoming important issues in the mining, comminution, materials handling, and construction industries. Screening or sieving methods, today’s standard method of sizing stone materials, are simply too inefficient for some applications, excessively time consuming and costly for others, and do not provide enough data for yet other applications. Optical methods using digital image processing, while not ready to replace sieving entirely, promise…

Technical and Computational Aspects of the Measurement of Aggregate Shape by Digital Image Analysis

Aggregates need to pass numerous tests to ensure the performance of asphalt and concrete structures and pavements. Some of these tests are fairly onerous, requiring manual, labor intensive, cost

Aggregate Classification by Using 3D Image Analysis Technique

Aggregate occupy approximately 80 percent of the total volume of concrete mix, and aggregate physical characteristics significantly affect the properties of concrete both fresh and hardened state.

Flat and Elongated: Advances using Digital Image Analysis

Coarse aggregate shape (flat and elongated) is an important issue in the highway industry. Elongated aggregates tend to break down during the asphalt emplacement process. Flat aggregates tend to lay

Digital Image Processing Based System for the Characterization of Coarse Aggregates

Aggregate characteristics have a significant effect on the properties of concrete in the fresh state and the hardened state. They also influence the quantity of cement paste required to fill the

Title : Measurement of Flat and Elongation of Coarse Aggregate Using Digital Image Processing

Coarse aggregate shape (flat and elongated) and angularity are important issues in the highway industry. Elongated aggregates tend to break down during the asphalt emplacement process, or align

Analysis of Aggregates By Image Processing Using Matlab

Aggregates need to pass numerous tests to ensure the performance of concrete structures and pavements. Some of these tests are requiring manual, labour intensive, cost ineffective measurements that

Automated Online Optical Sizing Analysis

The limitations of optical fragmentation sizing systems, the common errors that are made when implementing such systems, as well as the benefits and the proper way to use these systems are discussed, including some examples of applications.

Calibration of optical digital fragmentation measuring systems

Optical granulometry systems like WipFrag are required to measure fragments in situ. That is to say, the fragments are in piles where sorting takes place, where fragments are partially overlapped,
