PLASTIMIX 50

WATER-REDUCING CHEMICAL ADMIXTURE FOR CONCRETE 

DESCRIPTION:

Plastimix 50 is a ready to use lignin based liquid admixture formulated to enhance the performance of plastic and hardened concrete.  Plastimix 50 is manufactured under rigid quality control measures to provide uniform, reliable results.  

USES:

Plastimix 50 is designed to facilitate the placing and finishing of concrete, and is recommended for mixes where reduced water content and improved cement performance are desirable.  

ADVANTAGES:

·        Improves the quality of concrete by decreasing water-cement ratio

·        Increases early and ultimate compressive and flexural strength

·        Increases density and relative durability

·        Resists damage caused by freezing and thawing

·        Reduces water content needed for a given workability

·        Reduces cracking and shrinkage

·        Reduces surface bleeding

·        Reduces mix segregation

·        Provides variable control of setting time based on dosage rate

·        Improves pumpability of concrete

 DOSAGE RATE:

Plastimix 50 is recommended for use at a dosage rate of 3 to 5 fluid ounces per 100 pounds (196 to 327 ml per 100 kg) of cement to meet the requirements of ASTM C-494 Type A, normal setting water-reducer.

Higher dosages of Plastimix 50 are recommended for delayed set to meet the requirements of ASTM C-494 Type D as follows:

Below 65 F (18C) use 5 to 6 fl.oz. per 100 pounds (327 to 392 ml per 100 kg) of cement.

Between 65 F (18C) to 85 F (29C) use 6 to  7 fl. oz. per 100 pounds (392 to 460 ml per 100 kg) of cement.

Above 85F (29 C) use 7 to 8 fl. oz. per 100 pounds (460 to 526 ml per 100 kg) of cement.

Because local job conditions vary, contact your local Pro Mix sales representative for further assistance if using outside recommended dosage ranges.

SPECIFICATIONS:

Conforms to ASTM C 494 Type A

ASTM C 494 Type A , AASHTO M 194 Types A and D

CRD C 87 Types A and D

TECHNICAL NOTE:

Plastimix 50 does not contain any purposely-added calcium chloride or other chloride based components.  It will not promote or contribute to corrosion of reinforcing steel in concrete.

Due to the slight air entraining properties of Plastimix 50, as the dosage rate of Plastimix 50 is increased, the addition rate of air entraining admixture may be reduced by 50% to 70%.

COMPATIBILITY:

Plastimix 50 is compatible with all types of Portland cement, class C and F fly ash, slag, micro-silica, calcium chloride, fibers and approved air entraining and accelerating admixtures. For best results, each admixture should be dispensed separately into the concrete mix.

STORAGE:

Plastimix 50 may freeze at temperatures below 35 F (2 C).  Although freezing does not harm Plastimix 50, precautions should be taken to protect it from freezing.  If it should happen to freeze, thaw and reconstitute with mechanical agitation.  Do Not Use Pressurized Air For Agitation.

PACKAGING:

55-gallon drums and bulk deliveries.
