DELVO® ESC 

DELVO ESC (extended-set control) admixture provides a dispenser-free way of controlling the cement hydration in plastic concrete and washwater. It is a self-contained, dry formulation of DELVO Stabilizer admixture designed to control the hydration of cementitious material in concrete washwater and plastic concrete. DELVO ESC admixture meets ASTM C 494 requirements for Type B, retarding, and Type D, water-reducing and retarding, admixtures.

Features

• Reduced amount of water needed to clean ready-mix truck drums
• Reduced need for concrete washwater pits, the resulting wear and tear on front end loaders and disposal charges
• Concrete containing stabilized washwater will experience strength performance equal to or greater than reference concrete without stabilized washwater
• Acts as a cleansing agent to reduce the buildup on fins, reducing maintenance costs incurred from chipping out hardened concrete

Benefits

• Convenient way to save a load of concrete in emergency situations or job delays
• Economical for transporting concrete for long hauls
• Reduced labor costs of washing out trucks
• Reduced material costs, allowing for a cement reduction of between 47 and 94 lb (21 to 43 kg) when a full 9 yd³ (7 m³) load is batched on top of the stabilized concrete washwater (must be verified by performance testing)
• Improved profitability for the ready-mix producer
• Reduced environmental concerns pertaining to the disposal of concrete washwater and plastic concrete
