CONCRETE CEMENT TRUCK ADMIXTURE RETARDING MASTERPOLYHEED 844R SOLD PER LITER

Mid-Range Water Reducing and Retarding Admixture

POLYHEED 844R

Description

MasterPolyheed 844R admixture is a multicomponent, chloride free, mid-range waterreducing admixture, formulated to produce:

• A mid range water reduction (5 a 15%) an excellent performance through a wide range of mid-range slump, particularly in 150 a 200 mm slump in concrete placement

• Extended setting time throughout the recommended dosage

• Improved workability, pumpability and finishability, even in concrete mixes containing reduced amount of cementitious materials and/or concrete mixes containing fl y ashes

• Development of comparable compressive strength to that of the water-reducing and retarding admixtures

• Better performance with wide range types of cements, fly ashes, slag and aggregates

MasterPolyheed 844R admixture meets ASTM C 494 for retarding Type A admixtures, Type B for water- reducing admixture and Type D for waterreducing and retarding admixtures.

Recommended Use

All concrete where extended setting characteristics, and superior workability, and finishability qualities are desire, particularly in hot weather. MasterPolyheed 844R can be used for architectonic or colored concrete.

MasterPolyheed 844R can be used with airentraining, as long as it meets ASTM, AASHTO and CRD specifi cations.

Features

„ Reduces water content for a given slump

„ Improved time setting features

„ Increased development of compressive and flexural strengths

Benefits

MasterPolyheed 844R helps produce a quality concrete with the following special benefi ts:

„ Superior workability and pumpability in worm weather applications

„ Reduced bleeding and slump

„ Improves finishability in flat, formed or extruded surfaces.

„ Consistent performance in concrete mixes with low, mid-range of 150 to 200mm and high concrete slumps.

MasterPolyheed 844R is effective used by itself or as part of an admixture systems of BASF Construction Chemicals.
