MasterPozzolith RT 300 - Polymer admixture for improving concrete
How does MasterPozzolith RT 300 work?
MasterPozzolith RT 300 is a ready-to-use liquid admixture for making better, more uniform and more predictably high quality concrete. It retards the setting time to facilitate placing and finishing. Concrete meeting architectural, structural and construction requirements is obtained more dependably and economically with MasterPozzolith RT 300. MasterPozzolith RT 300 meets and exceeds the requirements of AS1478 Type WRRe and ASTM C 494 Type B and D admixtures.
- MasterPozzolith RT 300 admixture is recommended for use in all types of concrete where retardation of set and improved performance (particularly improved pumpability) are required or desired.
- MasterPozzolith RT 300 admixture improves pumped concrete, shotcrete (wet mix) and conventionally placed concrete; it improves plain, reinforced, precast, prestressed, lightweight or standard weight concrete.
- It can be used in white or coloured concrete.
- MasterPozzolith RT 300 can be used with air-entraining agents approved under AS 1478 Specifications when air-entrained concrete is specified or desired.
- BASF approved air-entraining admixture MasterAir is recommended for use with MasterPozzolith RT 300 admixture when air-entrained concrete is specified or desired.
When used in conjunction with another admixture each admixture must be dispensed separately into the mix.
What are the unique featues of MasterPozzolith RT 300?
While MasterPozzolith RT 300 entrains negligible air, it improves the efficiency of most air-entraining admixtures and will generally result in the need for less air-entraining admixture.
What are the benefits of MasterPozzolith RT 300?
Pozzolith 300Ri admixture aids in the production of concrete with these special qualities.
- Mild to extended retardation - depending on dosage
- Greater pumpability
- Superior finishing characteristics for slabwork and off-form surfaces
- Reduced water content for a given consistency
- Increased strength - compressive, flexural and bond of concrete to steel
- Greater economy in a mix designed for a given strength, slump and air content
- Minimum cracking
- Easier placement - economy in placement
- Greater durability
- Reduced segregation, particularly in lean mixes and high slump concrete
- Slipformed concrete
