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
