Product Info

Product Description

CONCRETE STONE (3, 3i & 3ib) is a washed coarse aggregate produced from the highest quality Ordovician Dolomitic Limestone. It is manufactured to specified physical properties and sizes. Because the material is washed, it contains minimal fines and reduced deleterious materials. Pattison Concrete Stone reduces the amount of costly additives required to produce concrete. It extends the life expectancy of roads, reduces cracks, freeze/thaw impacts and maintenance costs.

If you use our rock there is a good chance you can use less cement and have same break tests.
