þ
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
þ
DELVO® Stabilizer
DELVO
Stabilizer ready-to-use, liquid admixture is used for making more
uniform and predictable high-performance concrete. DELVO Stabilizer
admixture retards setting time by controlling the hydration of portland
cement and other cementitious materials while facilitating placing and
finishing operations. It can be used to stabilize returned plastic
concrete and concrete washwater to reduce waste and increase profits.
DELVO Stabilizer admixture meets ASTM C 494 requirements for Type B,
retarding, and Type D, water-reducing and retarding, admixtures.
Features
Reduced
water content required for a given workability
Retarded-setting time characteristics
Improved workability
Reduced
segregation
Benefits
Provides flexibility in the scheduling of placing and finishing
operations
Offsets
the effects of slump loss during extended delays between mixing and
placing
Reduces
waste associated with concrete washwater and returned concrete
Increased strength - compressive and flexural
þ
Pozzolith® 100 XR
Pozzolith 100 XR ready-to-use, liquid admixture is used for producing
more uniform and predictable quality concrete. Placing and finishing
requirements are facilitated because this admixture retards setting
time. Pozzolith 100 XR admixture meets ASTM C 494 requirements for Type
B, retarding, and Type D, water-reducing and retarding, admixtures.
Features
Reduced
water content required for a given workability
Retarded setting characteristics
Controlled retardation – depending on the addition rate
Benefits
Improved workability
Reduced
segregation
Superior finishing characteristics for flatwork and cast surfaces
Flexibility in scheduling of placing and finishing operations
Offsets
effects of too early stiffening during extended delays between mixing
and placing
Helps
eliminate cold joints
Dead-load deflection can take place (before concrete sets) in extended
pours for bridge decks, cantilevers, nonshored structural elements, etc.
Peak
temperature and/or rate of temperature rise in mass concrete lowered
thereby reducing thermal cracking
Increased compressive and flexural strength
þ
Pozzolith® 122 R
Pozzolith 122 R ready-to-use, liquid admixture is used for making more
uniform and predictable quality concrete while retarding its setting
time to facilitate placing and finishing operations. It meets ASTM C 494
requirements for Type B retarding, and Type D, water-reducing and
retarding, admixtures.
Features
Reduced
water content required for a given workability
Retarded setting characteristics
Moderate to extended retardation - depending on the addition rate
Benefits
Improved workability
Reduced
segregation
Superior finishing characteristics for flatwork and cast surfaces
Increased compressive and flexural strength
Flexibility in the scheduling of placing and finishing operations
Offsets
the effects of too-early hardening during extended delays between mixing
and placing
Helps
eliminate cold joints
Dead-load deflection can take place (before concrete sets) in extended
pours for bridge decks, cantilevers, nonshored structural elements, etc.
Peak
temperature and/or rate of temperature rise in mass concrete lowered
thereby reducing thermal cracking
þ
Pozzolith® 300 R
Pozzolith 300 R ready-to-use, liquid admixture is used for making more
uniform and predictable high-performance concrete while retarding its

Reduced
segregation
Superior finishing characteristics for flatwork and cast surfaces
Moderate to extended retardation - depending on the dosage rate
Benefits
Flexibility in the scheduling of placing and finishing operations
Offsets
the effects of too-early hardening during extended delays between mixing
and placing
Helps
eliminate cold joints
Dead-load deflection can take place (before concrete sets) in extended
pours for bridge decks, cantilevers, nonshored structural elements, etc.
