Cemgrout GPA
General Purpose Non-shrink Construction Grout Conforms to ASTM C 109, ASTM C827

PRODUCT DESCRIPTION

Cemgrout GPA is a ready-to-use, non shrink, cementitious compound that is specially blended using Portland cement, natural aggregate, expanding agent and chemical additives. It is non-corrosive and is free of chlorides and nitrates.

Cemgrout GPA is designed to exhibit different consistencies for multi purposes application by simply adjusting the water/ Cemgrout GPA ratio.

TYPICAL PROPERTIES

  1. Ease of preparation as Cemgrout GPA requires only the addition of a predetermined amount of water.
  2. Reduces site variations and errors as Cemgrout
    GPA is pre-mixed.
  3. Possesses good early strength even at pumpable consistency.
  4. Possesses non-shrinking property under restraint
    and is free of bleeding and segregation.
  5. Possesses excellent flow characteristics at
    pumpable and flowable consistencies even in
    difficult access areas.
  6. Is free of chlorides and metallic elements.

APPLICATION PROCEDURES

Surface Preparation:

  • All substrate surfaces should be free of loose,
    flaky materials, oil, grease and other contaminants.
  • All substrate surfaces should be clean and pre-wetted with clean water.
  • All free surface water should be removed before the application of Cemgrout GPA.

Prepairation of Cemgrout GPA:

  • Fill the appropriate amount of water for the required consistency (as given in the Performance Data below).
  • Add Cemgrout GPA slowly to the water and mix concurrently with a slow speed mixer (high shear paddle shall be used) until a lump-free and homogenous mortar is achieved.
  • Ensure minimal air-entrainment into the mix.

Application of Cemgrout GPA:

  • Apply the well-mixed Cemgroul GPA mortar onto the prepared surface within 45 minutes in order to gain the full benefit of the expansion process.
  • Cemgrout GPA may be applied, in a,one application, up to 100 mm thickness. For thicker application, the addition of clean and graded 6mm aggregate at the rate of 1:1 by weight is recommended. This is to minimise temperature rise.
  • If pouring or pressure-grouting methods are used, Cemgrout GPA mortar should be applied from only one side of the void in order to eliminate air entrapment and facilitate continuous grout flow.
  • The ideal temperature range for Cemgrout GPA mortar application is between 10 to 35C.

SAFETY PRECAUTION

  • Avoid direct contact with eye and skin although Cemgrout GPA is non-toxic.
  • Wear gloves and goggles.
  • Wash skin or affected area with clean water.
  • Avoid ingestion.
  • For more detail information please refer to the Material Safety Data Sheet
