Plast WRA 50

DESCRIPTION:

AT-PLAST WRA 50 is a highly effective water-reducing plasticiser for concrete industry.

STANDARDS:

It complies with IS: 9103, ASTM C 494/C 494 Type A, B & D, CRD-C-87 Type A & D and BS 5075 : Part I

USES:

  • Suitable for production of high quality ready-mix-concrete, pumped concrete, exposed and site-mixed concrete.
  • Recommended for general building construction, excavation and civil engineering during hot weather condition.
  • The application of AT-PLAST WRA 50 is to improve the characteristics of unset and hardened concrete.

CHARACTERISTICS:

  • AT-PLAST WRA 50 helps to produce desired quality concrete through reduction of the mixing water surface tension a liquefaction effect for increasing the consistency or the reduction of the mixing water to increase the compression and bending tensile strength.
  • AT-PLAST WRA 50 facilitates
    • Better settling capacity at the same w/c – value
    • Reduction of the w/c-value at the same consistency.
    • High initial and final strength
    • Conservation of cement
  • AT-PLAST WRA 50 exhibits excellent water reduction property; upto 12% approximately
