ARMORSIL Retarder is water reducing and set retarding admixture for concrete. ARMORSIL Retarder does not contain calcium chloride and other corroding materials. ARMORSIL Retarder temporarily stops the hydration process, delaying the initial setting time in proportion to the amount of dosaging. At the completion of the initial setting time, curing commence at an accelerated rate.
Primary Uses:
ARMORSIL Retarder is typically used to produce:
- Prestressed Concrete
- Concrete requiring water reduction and set time control
- Hot weather concrete placement
- Readymix concrete requiring long travel time from plant to site
- Ready-mixed concrete.
- Pumped concrete.
Features and Benefits
ARMORSIL Retarder offer the following advantages and benefits:
- Retards setting characteristics
- Improves workability
- Reduces water requirements
- Reduce Segregation
- increases strenght
- Reduces permeability
- Reduce cracking
- Improves finish appearance
Technical information
ARMORSIL Retarder meets the requirements of the following standards:
- ASTM C 494, Type B & D
- AASHTO M 194
Packaging
ARMORSIL Retarder is packaged in 20 litres drum and 200 litres drum . Bulk supply in delivery trucks can be arranged on demand.
Colour and Appearance:
Brown Liquid
Consumption and Direction for use :
Typical dosage would be between 0.5 % to 3% depending on the intended duration for extending set time. Note that the actual dosage for any situation would depend on trial mixes, the initial extension of the required set time, temperature and cement type.
