RHEOFIT 1141 

RHEOFIT 1141 is an integral admixture designed to reduce the rate of transmission of moisture through concrete.

RHEOFIT 1141 is based on purified stearic acid supplied as a white pourable emulsion.  It does not contain water reducers, accelerators, air entraining or surfactant chemicals that might cause undesirable side effects when used in conjunction with admixtures normally used in concrete.  RHEOFIT 1141, used as an integral admixture in concrete, reacts with the cement hydration process to form a hydrophobic coating on pores and voids in concrete, reducing capillary suction and minimising absorption and penetration of water.

RHEOFIT 1141 is classified by AS 1478.1-2000 Appendix F as a Class F4(c) Admixture.

RHEOFIT 1141 is recommended for:

• most applications requiring watertight concrete such as basement walls and floors, tunnels and silos
• concrete blocks and bricks
• low cement content panels and cladding
• wall and tank foundations, renderings
