Description

A concrete plasticizer specially designed for Roller Compacted Concrete
(RCC) structures.
USES
For structural and mass concrete where long setting times and
improved workability are required, such as projects with:
 Large pours, to prevent formation of cold joints in RCC dams etc.
 Long travel times from the concrete plant to the site
 Difficult placing conditions and details
 High ambient temperature
ADVANTAGES
WET RCC
 Initial setting is delayed allowing time for proper placement and
compaction of a new layer on top of the retarded RCC without a cold
joint.
 Decreasing the mortar volume of the bonding concrete.
 Extending the compaction time, as heavy transits can damage the newly
hydrated RCC.
 Increasing the cement efficiency.
 Reducing the rate of initial heat generation.
Hardened RCC
 Higher mechanical strength in any weather condition.
 Diminished heat generation and the risk of cracking
 Increased density of the RCC
