CBCM cement products

Two strength bands. Six distinct cement products.

Start with the strength your buyer already knows: 42.5 or 52.5. ASTM Type IS (20) appears with the 42.5-strength products because its published 28-day result is 44.1 MPa and is sold under its full ASTM C595 designation.

Shop by strength

Start with the number your buyer recognizes.

Every product keeps its standard and full designation front and center, making it easy to compare and price the exact cement.
