UEA-H is powdered material, which made by grinding special mineral together with additives. The fineness is less than 10%;the specific weight is 2.90; Non-toxic, non-odour; No ammonia, no chlorine.

□ Features

• Low adding amount. High expansive rate.
• Alkali aggregate reaction can be inhibited effectively due to low alkali content.
• No influence upon the strength of concrete. It can be substituted by cement equivalently.
• Slump loss of concrete does not increase. Good workability.

□ Performance

• As preparing shrinkage compensated concrete, if the ratio of reinforcement is 0.2%~0.8%, the limited expansive rate will be in the range of 0.02%~0.04%, and a prestress of 0.2~0.7Mpa exists in the concrete.
• Comparing with the concrete without UEA-H in the condition of defined mixing amount, the free strength of the concrete with UEA-H is roughly equal to that of concrete without UEA-H. The limited strength is 10%~15% higher than free strength.
• The impermeability grade of mortar and concrete can reach over S30. The elastic ratio closes to that of common concrete.
• Sulphu-ate resistance of concrete is increased. No pollution to water.

□ Application

• For structural self-waterproofing.Effectively preventing cracking or leakage of concrete
• TO extend the space length of post casting zone of cast-in-place overlength structure
• To control the crack producing result of temperature difference in largesized structural concrete
• For rigid roofing

Compatibility with other additives
UEA-H is compatible to most of additives.Such as high performance reducer,pumping aid,accelerator;retarder,antifreeze,etc of naphthalene series additives and resin series additives.

Technology support
We would like to offer our full technology support,which backed by China Building Materials Academy to our customers.It is available for our technical proposal and assistance for the design of concrete mixing ratio in lab or in construction site.
