ZM-6 Expanding Agent (Concrete Multi-Purpose Expansion Agent)

ZM-6 is composed ofefficient low-alkaline expanding, air-entraining and retarding ingredients. Ithas expanding, waterproof and air entraining functions and can obviouslyincrease cracking resistance, anti-permeability, waterproofing and freezingresistance. It is applicable to compensation shrinkage concrete, waterproof andanti-permeable concrete and large-volume concrete and has been successfullyapplied to multiple domestic engineering.

I.  Main technical performance

1.    Increase compactibility of concrete. Anti-permeabilitygrade:＞ P40.

2.    Compensate shrinkage of concrete to avoidcracks occurring.

3.    Effectively increase anti-freezing andwaterproof performance of concrete.

4.    Slight slump loss of the concrete mixture andgood workeability reduce pumping pressure and abrasion between concrete andpump pipes.

5.    Good adaptability to concrete.

6.    No chlorine salt to corrode reinforcingsteel bar.

7.    Good freezing resistance when constructionis in winter.

II.      Usage and precautions

1.    This product is powder and the recommended mixingamount is 6.0-12.0%. The appropriate mixing amount shall be determinedaccording to engineering requirements and specific conditions. The mixingamount shall be increased appropriately when construction is in winter.

2.    The simultaneous mixing method, the priormixing method, the stagnant water method could be adopted.

3.    In order to guarantee quality ofengineering, our plant provides the technical consulting for users and willdispatch the technical personnel to the site according to users’ demands.

III.     Package and storage

1.    Plastic bags in double-layer, net weight:50kg/bag.

2.    It shall be stored at the ventilated dryplace to avoid moisture.

3.    Shelf life: 2 years.
