Direct Answer: Concrete mixes containing soft high-sand aggregates or uncured green concrete generate sharp abrasive slurry that washes against the steel core below diamond segments, causing undercutting failure. Combat undercutting by specifying hard nickel-alloy bond matrix blades equipped with recessed drop segments or carbide core inserts that deflect slurry away from the weld line.

What is green concrete?
Green concrete is freshly poured concrete that has set (4 to 8 hours old) but has not fully cured, producing highly abrasive slurry when cut.
