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:How does the cement produce! What matter! Why did she get angry?
Cement - Inorganic cementitious materials Add water into the slurry after mixing, in the air or water hardening, and can sand, stone and other materials firmly cemented together Cement is an important building materials, made of cement mortar or concrete, durable and durable, widely used in civil engineering, water conservancy, defense and other projects
Q:Hanging on cement?
Hook and loop (velcro) tape. Glue one side to your item, and one side to the cement....larger pictures will need tape around all four edges to be secure, but it does work - I've done it before. Hope this helps. Good luck!
Q:Why do people call a concrete mixer a cement mixer?
Because cement is the mortar mixture used to make concrete. Concrete is cement mixed with aggregate like sand or gravel for building purposes. But you can mix cement without adding anything to it. So the mixer is a CEMENT mixer, NOT a concrete mixer.
Q:How to bond bricks/cement in a cost effective manner?
cement is your best answer. Mortar to be exact. Anything else is a poor substitution to the right product for the job
Q:can you make paint from cement mix?
You can use powdered cement products mixed with a bonding solution as the liquid to enhance their stickiness, and you can also use concrete dyes to match a lot of different colors. These products are available at most big box retailers in their concrete area. The dyes are about $6 for a 12 oz. bottle
Q:What is the meaning of 53 grade cement ?
The grade of a portland cement corresponds to how much pressure it can take after it has set for 28 days. 53-grade cement must have a compressive strength of 53 MegaPascals (7687 pounds per square inch) after 28 days. There are also 33 and 43 grades, which must have minimum compressive strengths of 33 and 43 MPa respectively.
Q:Greenboard or cement board ??
it really depends on what is going on top of the board. if I am using ceramic tile around a tub/shower, I use greenboard. If the tile is granite or porcelain, or will be installed overhead, use wonderboard (cementboard). The additional weight of the tiles could potentially pull the green paper away from the Gypsum. Greenboard is easier to cut For anywhere else i would use either greenboard, or regular drywall and mold/mildew resistant paint, and a new more powerful ceiling exhaust.
Q:how do i make cement dry faster?

Q:Shoe Goo or Barge Cement?
This is a very active forum with some very knowledgeable people if you wish to ask additional questions there.
Q:35 tons of the concrete mixture is made of cement, gravel, and sand mixed with the ratio 3:5:7 respectively.?
7 tons of cement 11.67 tons of gravel 16.33 tons of sand. Say X is the amount of cement (don't worry about the 3). How much gravel is there in relation to cement? 5/3 as much.For every 3 of cement, there's 5 of gravel. How about the sand? There's 7/3 as much sand as there is cement.So now you can restate the whole thing with respect to cement: However much cement + 5/3 more gravel than cement + 7/3 more sand than cement = 35 tons. X + (5/3)X + (7/3)X = 35. X ends up equaling 7, (5/3)X is 11.67, and (7/3)X is 16.33. Hope this helps!
