Description
Want to understand the actual shape and morphological characteristics of your sand or gravel particles beyond conventional particle-size measurements? Our Sand & Gravel Particle Shape and Morphological Analysis service uses digital image processing with MATLAB and Fiji (ImageJ) to quantitatively characterize individual particles.
This service is suitable for researchers, civil and geotechnical engineers, geologists, construction-material specialists, mining professionals, and postgraduate students studying how particle geometry influences the behaviour and performance of granular materials.
Depending on your project requirements, we can determine important morphological parameters including sphericity, angularity, circularity, convexity, particle length, particle width, and length-to-width ratio (aspect ratio). Digital images are processed and analysed to obtain numerical measurements rather than relying solely on visual particle classification.
The service can accommodate sand particles up to approximately 4 mm and gravel particles up to approximately 20 mm, subject to sample characteristics and imaging requirements.
Your report can include processed particle images, measured morphological parameters, summary statistics, tables, plots, and interpretation of the results where required. If you're carrying out academic research, you can also send us your methodology or research objectives so we can structure the analysis and output around the parameters required for your study.
Parameters Available:
Sphericity: evaluates how closely the particle geometry approaches a spherical form.
Angularity: evaluates the degree of sharpness or angular characteristics of particle boundaries.
Circularity: quantitatively describes how closely a particle's two-dimensional projection resembles a circle.
Convexity: evaluates particle-boundary irregularity in relation to its convex representation.
Length/Width Ratio (Aspect Ratio): compares the major and minor particle dimensions and helps identify elongated particles.
Additional image-derived morphological parameters may be available depending on your research requirements.

Packaging Instructions
Submit sand and gravel samples in separate, clean, securely sealed containers or sample bags.
Clearly label each sample with a unique sample ID.
For sand, the maximum particle diameter for this service should generally be 4 mm.
For gravel, the maximum particle diameter should generally be 20 mm.
Ensure sufficient representative material is provided for particle selection and imaging.
Samples should preferably be dry and free-flowing unless the research methodology specifically requires another condition.
Prevent mixing, crushing, or abrasion of particles during transportation.
Use rigid secondary packaging for gravel samples to prevent the package from tearing during transit.
If different particle-size fractions have already been separated, package and label each fraction individually.
Include your research objectives or required morphological parameters with the samples.
Other Instructions
Please tell us the approximate particle-size range and number of samples before submission.
If you require a specific number of particles to be analysed per sample, state this before testing begins.
Provide your existing research methodology if the analysis must follow a particular published or institutional procedure.
Fiji (ImageJ) and MATLAB may be used for image segmentation, particle measurement, morphological computation, data processing, and statistical evaluation as appropriate.
Image-derived parameters can depend on particle orientation, image acquisition, segmentation, resolution, and the mathematical definition used. The methodology and definitions should therefore be agreed upon for research requiring strict comparability.
The standard service primarily evaluates 2D image-derived particle morphology. It should not automatically be interpreted as direct three-dimensional particle-shape measurement.
Additional statistical analysis, comparison between sample groups, custom MATLAB algorithms, or publication-ready figures can be included at additional cost.
Please tell us in advance if the results are intended for a thesis, journal publication, engineering investigation, or other project requiring a particular reporting format.
