UEA-M Multi-functional
         High Efficient Expansion Agent for Concrete
    
Features
    *Have the functions of water reducing ,setting retardation,
early strength, anti-freezing and mobility.
    *Improves the structure and grading of the void in the concrete
 apparently,lower the permeability of the concrete.
    *Cause 0.2-0.7MPa compressive pre-stress in the internal part
 of the concrete structures under unrestrained and  load- freed 
state,compensate the shrinkage.
    * Apply for water proof/moisture proof of reinforced concrete
 structures.* Increase the proper distance of expansion joints.

Usage and Caution
    1)Should be test in laboratory to determine mix ratio with
concrete before use.
    2)Use level is 6.0-8.0% of binding material weight,may mix
 with cement,sand, stone,water. In the part of needing high expansion energy, 
use level is 8.0%-10%.
    3)Please comply with the application technology rules of
 extra agent for concrete.
