Daltex White Flint 2-5mm is a pure white angular calcined flint with flecks of red and black. This creation is very unusual and is great when used in mixes.
This aggregate can be used to create a statement, border or as a feature on its own. It can be used as a base in which to mix other colours such as black, green or red. It can also be used to give contrasting highlights, when added to other much darker aggregates.
This aggregate is not suitable for use in Resin Bonded applications.
We strongly recommend the use of UVR resin with all DALTEX 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.

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.
