8inch Hydraulic Concrete Arch Block

We are offering 8inch Hydraulic Concrete Arch Block.
Dimension 8"*6"*12" Arch Block
We use high quality raw materials like Fly Ash, 4mm unsegregated fine aggregate, 6mm coarse aggregate and 12 mm coarse aggregate to ensure good compressive strength.
Advantages of using Fly Ash in brick block:
Increased Compressive Strength
No leaching of Calcium Hydroxide crystals onto the surface (those white patches)
Increased Durability -(low Chloride Ion penetration, i.e. very low coulomb rating that further decreases
with time).
Decreased Permeability
Reduced Sulfate Attack
Reduced Drying Shrinkage
