The Daltex Black 2-5mm is a plain aggregate that can be used on it's own or better still with a mix of red or white to add character. It can be used as a slight percentage mix into virtually any other product to produce a strong black fleck that adds texture and contrast. An angular granite aggregate for strong adhesion.

We strongly recommend the use of UVR resin with all DALTEX dried aggregates.

ACV - 12

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.
