portland cement 42 5            

 

1.Product range: P.C32.5, P.C.32.5R, P.O42.5,P.O.42.5R, P.S.A42.5, P.O52.5, P.O52.5R, P.I52.5, P.I52.5R,P.S.A32.5 Ordinary Portland cement

 

2.Standard: In compliance to the nationalstandards (GB175-2007)

 

3.Packing:   

   

a)2MT jumbo bag

 

b)50kg per bag then 40 bags into a 2MT sling bag

 

C)50kg bag

The typical performance during using:

 

1. Steady and high quality, low fluctuate, and rich in strengthgrade.

2. Good workability and adaptability with additives.

3. Long term steady in color, wide used in the construction ofmodest color building.

4. Low bleeding, be applicable to produce concrete.

5. Freeze-proof, abrasion resistance.

6. Steady solidity ratio, the volumetric shrinkage basicallyreach to balance at one-year age, up to the high standard ofinternational and domestic.

7. Meanwhile, its low slump loss meets the need of the longdistance delivery of concrete-mixer.

 

Attention:

 

1. Pay attention to store, and avoid moisture.

2. Cannot mix different type cement together.

3. To select certain type and grade cement reasonablly.

4. Stick to pre-testing of concrete.

5. To carry out specility testing, work out the best mixratio.
