Product Description:

Rapid-hardening cement 42.5 grade.


It is a kind of high early strength cement.

The product obtained by grinding cement clinker obtained by roasting suitable raw material, consisting essentially of anhydrous calcium sulphoaluminate and dicalcium silicate. Suitable gypsum and 0-10% limestone shall be blended with clinker during manufacture of rapid-hardening sulphoaluminate cement. The product is hydraulicity binding material. It has high early strength. The code no is R-SAC and with four grades.


Main Specification

1.Specific surface area(m2/kg): ≥350

2.Setting time(min):

initial setting time: ≥25

Final setting time: ≤180

(Remark: the setting time can be adjusted according to the customer’s demand.)


Strength data in different ages:


Compressive strength (Mpa)

Bending strength (Mpa)





































1)      High early strength and high strength properties

Its compressive strength can reach 35-50Mpa within 1 day, 50-70Mpa after 3 days, and it also can grows continually with the increasing of curing age.

2)      High froze-resistance property:

If used at the temperature as low as 0-10°C,which early strength is 5-6 times than that of OPC; if used in 0-20°C with little admixture, its strength in 3-7d can reach 70-80% of designed strength, with very little strength loss after 300 times of froze-thaw circle.

3)      High impermeability: because of its dense structure, the impermeability of the concrete is 2-3 times than that of OPC in same grade.

4)      Anti-carbonation property: it has good anti-carbonation property, and low dry-shrinkage.

5)      Corrosion-resistance: it has good corrosion-resistance quality, especially much better in seawater corrosion resistance than that of high anti-sulphate Portland cement, with more than 1 corrosion-resistance coefficient.

Q:List three common cements. How might each be identified?
Three common cements for sedimentary rocks are calcite, silica, and iron oxide. Each can be identified by calcite cement will fizz with dilute hydrochloric acid, silica is the hardest cement producing the hardest sedimentary rocks, and sedimentary rocks with an iron oxide cement has an orange or red color.
Q:Can you lay cement board in order to put vinyl flooring?
as long as you're putting the cement board over a solid surface and not joists. Make sure the smooth side is up and all the joints are tight.
Q:how to paint house exterior which is cement plaster?
Use Acrylic paints on the cemented exterior walls. There is a wide range to choose exterior paints. They have anti dirt paints, 100% acrylic paint, exterior matt finish, etc.
Q:Is it wrong to fill bamboo poles with cement?
filling them with cement or like material will keep any moisture trapped in there and also weight them down. fill them with lightweight expanding foam and after it is completely dry you can cut away the excess so it looks the same
Q:How long does it take cement to dry?
First of all it is concrete not cement and second of all it doesn't dry, it cures. It is a chemical reaction, it does not just simply dry out like mud brick. Given that, there are too many variables to take into account, thickness, environmental conditions, the exact formula of the concrete mix, etc.
Q:Does rubber cement warp plastic?
Q:Can you get rid of graffiti in cement?
first, tell the police, so it wont happen again. try using water and lots of soap. Just and idea! Good luck.
Q:What is slag cement? What are its advantages/ disadvantages over OPC?
Advantages Of Slag Cement
Q:Due to rising prices of building materials, and the impact of the progress of the project, need to make a report, such as how to write
First of all, should be based on the terms of the construction contract conditions, to figure out the scope of the adjustment of the unit price increase or decrease
Q:Any one know the differnt ratios of sand and cement for the different strengths of concrete eg. 25N 35N etc.?
Cement to aggregate ratios do not determine concrete strength. The water to cement ratio is what determines strength. Sand, gravel and other aggregates act as a bonding agent. Normal ratio is 7-15% cement to 14-21% water with remaining percentage as the aggregate.
Our company has our own research organization-cement and concrete research lab, which is fully equipped with up-to-date facilities. Our products have been exported to South Africa, Australia, the United Kingdom, Korea, the United Arab Emirates and Taiwan Area.
