Donplast PC430
High range water reducing admixture based on polycarboxylate polymers
Donplast PC430 is a high range water reducing admixture based on polycarboxylic polymers with selective additives which are especially formulated to enable the water content of the concrete to perform in a more effective manner.
This effect can be used in different concrete applications where it is required to keep the water-to-cement ratio at a
minimum level while maintaining an excellent workability and strength performance.
- Optimizes cement utilization.
- Can be used as high range and normal range water reducer depending on the used dosage.
- Improves the water impermeability characteristics of concrete mix.
- Improves the slump retention characteristic without affecting the setting time.
- Increases the durability and resistance to aggressive atmospheric conditions.
- Significantly improves early and ultimate compressive strengths.
- Minimizes segregation and bleeding problems by improving the cohesion of concrete mixes.
Donplast PC430 is suitable for use in the following applications:
- Acts as high range water reducer for the production of high strength and high performance concrete.
- Can be also used as normal range water reducer for low and mid-rise constructions.
- Structures with congested reinforcement.
- Precast/Prestressed concrete.
- Concrete mixes containing Silica Fume, GGBFS or PFA.
Donplast PC430 is available in 25 litre pails, 210 litre drums and 1000 litre bulks supply.
Donplast PC430 has a minimum shelf life of 18 months from date of manufacture if stored at temperatures
between 2°C and 50°C.
The recommended dosage of Donplast PC430 is 0.7 to 1.5 litres per 100 kg of cement or cementitious materials in the mix including GGBFS, PFA or micro-silica.
Representative trials should be first conducted to determine the optimum dosage of Donplast PC430 to meet the performance requirements by using the materials and conditions in actual use.
Donplast PC430 complies with the requirements of Specification for Chemical Admixture for Concrete ASTM
C494 as a Type A and F admixture, depending on the used dosage.
