Water reducer for concrete - MORTARPLAST 951

MORTARPLAST 951

Super plasticizer and a water reducer for concrete

DESCRIPTION

MORTARPLAST 951 is a dark colored ready to use super plasticizer based on synthetic polymers with high molecular

weight and increased fluidifying power.

During summer time and in hot climates, MORTARPLAST 951 SR helps to obtain strong delays from the beginning of setting time and extends the consistency and workability of the concrete.

MECHANICAL STRENGHTS

Compared to a concrete without the admixture, the use of the admixture in concrete will result in an increase in the

mechanical strength in proportion with water reduction. Because of the reduction in the water/cement ratio, high initial and ultimate mechanical strengths, increased resistance and

durability, lower shrinkage and permeability will be obtained

During winter time, MORTARPLAST 951 W accelerates the setting

time and obtains high initial strengths.

MORTARPLAST 951 is designed for spring and fall temperatures.

STANDARDS

MORTARPLAST 951 SR; ASTM C-494 Type G MORTARPLAST 951 W; ASTM C-494 Type F

MORTARPLAST 951; ASTM C-494 Type F

DOSAGE AND USE

The dosage of is 0.6 – 1.5 kg for every 100 kg. of cement, to be added in mixer with the last mix water.

( after 70% introduction of the mix water ).

The addition of admixture on dry aggregates and cement is not recommended since it lowers the plasticizing and water

reducing effect.

FIELD OF APPLICATION

MORTARPLAST 951/ 951 W / 951 SR can be used on all types of high quality concrete where a good mechanical strength and significantly lower w/c ratio is needed.

Due to it’s characteristics, it is particularly indicated for use in concrete mixed on site or ready-mixed concrete transported by mixer trucks.

ADVANTAGES

MORTARPLAST 951 / 951 W / 951 SR is a super plasticizer and within a dosage range from 0.6 – 1.5 %, the following can be obtained;

• Concrete with an improved w/c ratio. ( water reduction of 10 - 25 % )
• Waterproofing concrete.
• Non segregating, fluid, plastic concrete without bleeding.
• Homogeneous and cohesive concrete.
  • Easily pumped concrete with good workability and with good finishing.
  • Durable and highly impermeable concrete.
  • Improved properties of fresh and hardened concrete.
  • Concrete with high initial and final strengths.

WORKABILITY

Workability time after the use of the admixture in the concrete depends on the applied dosage, type and dosage of cement

and aggregates and ambient temperature.

In general, the extended workability time after the addition of the admixture at 200C. is;

MORTARPLAST 951; < 90 minutes

MORTARPLAST 951 W; < 60 minutes

MORTARPLAST 951 SR; < 120 minutes

The loss of workability is gradual and only practical site tests will specify the workability.

PRECAUTIONS

Use gloves and avoid contact with eyes and skin. Consult a physician if contact with eyes and skin.
