PolyBound Red 1-3mm is a finer grade of our red granite chippings. Used to mix in with the PolyBound Red 2-5mm to fill voids and add strength to mixes or to use in Resin Bonded applications.
Also available in Red 1-2mm and Red 2-5mm.
We strongly recommend the use of UVR resin with all PolyBound dried aggregates.
Non UVR resin darkens and fades over a very short period of time and has a natural tendency to discolour. It should never be used with this aggregate.

- Low risk of iron staining with this aggregate.
PSV – Polished Stone Value
The PSV of an aggregate is a measure of the resistance of an aggregate to polishing and the value is established by subjecting the aggregate to a standard polishing process and then testing the aggregate with a portable skid resistance tester. Aggregate that has a PSV over 60 is regarded as a High Skid Resistant Aggregate. The higher the PSV figure the greater resistance the aggregate has to polishing.
AAV – Aggregate Abrasion Value
A known mass of aggregate chippings are set in resin in a small test panel and subject to abrasion on a grinding apparatus. The loss in weight of the aggregate after a specified time as a percentage of the original weight is the AAV.
AIV – Aggregate Impact Value
The aggregate impact value is a strength value of an aggregate that is determined by performing the Aggregate Impact Test on a sample. The AIV is the percentage of fines produced from the aggregate after subjecting it to a standard amount of impact. Below 10 would be regarded as strong, above 35 would normally be regarded as too weak to be used in road surfaces.
ACV – Aggregate Crushing Value
The aggregate crushing value is a value which indicates the ability of an aggregate to resist crushing. The lower the figure, the stronger the aggregate ie the greater its ability to resist crushing.
