Plastimix MRP

MID-RANGE WATER-REDUCING ADMIXTURE FOR CONCRETE

DESCRIPTION:

Plastimix MRP is a multi-component water-reducing chemical admixture, which is carefully formulated to enhance the quality and performance characteristics of plastic and hardened concrete.  It’s unique chemistry results in more complete and efficient hydration of the cementitious materials in the concrete matrix, providing more psi per pound of cementitious materials, improved early and ultimate strength as well as improved concrete durability.

USES:

Plastimix MRP has been designed specifically to meet the needs of concrete paving industry.  Plastimix MRP is a versatile and powerful tool that can be used to reduce the w/cm ratio as well as improve bond strength in order to achieve higher flexural and compressive strengths.  It is also a very effective solution to the need for increased workability (higher slump) for hand placements without increasing the w/cm ratio or compromising the concrete quality.  (A conventional 2” slump slip form paving mix can be converted to a 5”+ hand placement mix simply by adding Plastimix MRP)  This can eliminate the slump loss, higher water demand and increased shrinkage and cracking potential often seen in traditional hand placement mixes.

The improved paste qualities made possible by Plastimix MRP also improves concrete “slipability”, finishability, and overall pavement appearance.

Plastimix MRP is manufactured under rigid quality control measures to provide uniform, reliable results.

ADVANTAGES:

·        Improves the quality of concrete by decreasing water-cement ratio for a given workability

·        Increases early and ultimate compressive and flexural strengths

·        Provides superior finishability on all slip-formed and hand placed concrete

·        Improves surface quality

·        Improves workability and ease  of placement and consolidation

·        Improves pumpability of concrete

·        Provides uniform, normal-setting characteristics

·         Reduces cracking potential

SPECIFICATIONS:

Conforms to ASTM C 494 Type A and F

ASTM C-1017 Type 1

AASHTO M 194 Type A and F

CRD C 87 Type A and F

DOSAGE RATE:

Plastimix MRP is recommended for use at a dosage rate of 5 to 14 fluid ounces per 100 pounds (325 to 910 ml per 100 kg) of cement.  Because local job conditions vary, please contact your local Pro Mix sales representative for further assistance if using outside recommended dosage ranges

TECHNICAL NOTE:

Plastimix MRP 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.

STORAGE:

Plastimix MRP may freeze at temperatures below 35 F (2 C).  Although freezing does not harm Plastimix MRP, 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.

COMPATIBILITY:

Plastimix MRP is compatible with all types of Portland cement, class C and F fly ash, slag, microsilica, calcium chloride, fibers and approved air entraining, accelerating, retarding, and super plasticizing admixtures.

Field evaluations to determine proper air entrainment dosage rates are suggested when using Plastimix MRP.  It may be possible to reduce the air entraining admixture dosage rate to achieve the desired air content of the concrete mix.

Plastimix MRP can be used in all white, colored, and architectural concrete.  For best results, each admixture must be dispensed separately into the concrete mix.

PACKAGING:

55-gallon drums and bulk deliveries.
