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:
Grade | Compressive strength (Mpa) | Bending strength (Mpa) | ||||
1d | 3d | 28d | 1d | 3d | 28d | |
42.5 | 33.0 | 42.5 | 45.0 | 6.0 | 6.5 | 7.0 |
52.5 | 42.0 | 52.5 | 55.0 | 6.5 | 7.5 | 7.5 |
62.5 | 50.0 | 62.5 | 65.0 | 7.0 | 7.5 | 8.0 |
72.5 | 56.0 | 72.5 | 75.0 | 7.5 | 8.0 | 8.5 |
Properties
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.
Applications
1. Construction in winter.
2. Urgent repairs and rapid construction.
3. Spraying anchor and supporting engineering.
4. Water conservancy facilities and offshore projects.
5. Bridge and road construction.
6. Cement products and prefabricated components.

- Q: i need home work help
- What Is Cement Used For
- Q: We have a very low slope roof, nearly flat. A local roofer proposed to redo it using only a base sheet and roofing cement. This sounds like it's probably a cheaper cut corner way to do it. Is this common?
- I'm no expert, but I have the same kind of garage roof and I've had it done twice in 17 years with the rolled roofing and if it's done right, they didn't even use cement. I confess, the first time I fixed it myself and I did use the roofing cement. It was fine but I never did get the gutters on right, forgot the drip cap and so the back end of the roof rotted within 4 years. Eventually I had a handy man redo it and he did a better job that lasted for awhile, but a wind storm ripped it half off after about 6 years. My neighbors don't have nearly as many problems as I do with their garage roofs. In fact, I've never seen them repairing theirs. I'm actually in the midst of getting roofing bids myself, for the house and the garage. I've heard a lot about the rubber roofing on garage roofs but I've seen some bad reviews for that. I've gotten some good information from my city building inspectors on their opinions and they are unbiased. Good luck to you.
- Q: and it was lumpy can i still use it or will the lumps interfer with the leveling process, ( and how liquidy should i make it) i experimented with a little amount and it just didn't look right so i threw it out.. it's the firt time i'm using a self leveling product
- On self leveling cement, make the mix super liquid at first and then use a power drill and a paint mixer mixing it very thoroughly and completely, Then add a bit more of the dry cement to the liquidy mix until you get a consistency of about a thin tooth paste. The key here is to make it liquidy, then thicken it back by adding more dry cement powder until you get it just right. Now before you go applying this to an existing concrete surface, take brush and wet down that concrete with water. Get it good and wet but not puddled on there. Wait 10 minutes or so for the old concrete to absorb the water. Then take and pour that above mix onto there and start leveling with a flat piece of aluminum or a flat boards edge.
- Q: Can a grenade blow through brick/cement wall?
- Why are you planning to hide behind a brick/cement wall? LOL!! Yes depending on what type of grenade is deployed a brick or cement wall is nothing to blow through. You would be surprised at what a concussion grenade will do to a wall.
- Q: if i have a footing 22ft long by 18inches deep by 10inches wide how many yards do i need
- 27 1/2 divided by 1760. Abhijit.
- Q: why is cement and water the ingredients of mortar allowed?
- We seem to be thinking alike...;0)
- Q: The date on the bags is from Jan 2006.Placed a sample in a plasticplate, mixed with water and the next day the quot;concretequot; was brittle to where just pressing with the finger causes it to crumble.The bags were kept off the floor in a garage.There are a few small lumps in each bag but for the most part its in quot;goodquot;powder form.Can I use these cement bags for any other use? Can it be mixed with good cement at a given ratio for a sidewalk concrete mix? Thanks
- Test it again using sand/cement mix 4:1 with minimal water, and leave it for at least 3 days before feeling the strength. If it is still no use then you could treat it as inert, say 10% of good cement, but better to dump it. The date on cement also relates to the slow formation of hexavalent chromium compounds which build up to 'risky' levels and cause dermatitis and other allergic conditions. For this reason, it's well worth wearing protective clothing when handling cement powder and wet concrete.
- Q: design criteria for cement concrete
- Here in Indiana we do the following: Water/Cement ratio Slump Air Content Yield Beams for Flexural Strength Cylinders for Compressive Strength
- Q: what is the difference between cement and concrete ?
- Cement is a bonding agent (lime). Concrete has cement, aggregate (small rocks), and sand. You add water to a concrete mix to cause a chemical reaction that makes it solid.
