MasterPozzolith RT 300

Polymer Admixture for Improving Concrete Quality by Retarding Setting Time

How Does MasterPozzolith RT 300 Work?

MasterPozzolith RT 300 is a ready-to-use liquid admixture formulated to enhance the uniformity and quality of concrete by retarding the setting time. This facilitates better placing and finishing, resulting in concrete that meets architectural, structural, and construction requirements more reliably and economically. MasterPozzolith RT 300 meets and exceeds the requirements of AS1478 Type WRRe and ASTM C 494 Type B and D admixtures.

Recommended Uses:

• All types of concrete where retardation of set and improved performance (particularly improved pumpability) are required or desired

• Pumped concrete, wet mix shotcrete, and conventionally placed concrete

• Plain, reinforced, precast, prestressed, lightweight, or standard-weight concrete

• White or coloured concrete

• Can be used with air-entraining agents approved under AS 1478 Specifications when air-entrained concrete is specified or desired

• Recommended to use Master Builders Solutions approved air-entraining admixture MasterAir when air-entrained concrete is specified or desired

What Makes MasterPozzolith RT 300 a Unique Solution?

While MasterPozzolith RT 300 entrains negligible air, it improves the efficiency of most air-entraining admixtures and generally results in the need for less air-entraining admixture.

What Are the Benefits of MasterPozzolith RT 300?

MasterPozzolith RT 300 admixture aids in the production of concrete with these special qualities:

• Mild to extended retardation depending on dosage

• Greater pumpability

• Superior finishing characteristics for slab work 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

• Improved performance in slip-formed concrete applications
