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.

- Q: i need home work help
- Cement is used to make concrete! 1part cement to 3 parts sand 2 parts water is one form of concrete! Pebbles and lime can also be added! After everything is mixed it can be made into many things! House foundations, Walls, Piers, supports for bridges, roads, buildings! You name it! Cement is a valuable resource!
- Q: What's the difference between concrete, asphalt, and cement?
- Concrete. Period.
- Q: Explain why. Don't just give a yes or no answer. Full details
- because aliens dont wear hats.
- Q: Is there a difference between cement and concrete?
- Yes there is a big difference. What is the difference between cement and concrete? Although the terms cement and concrete often are used interchangeably, cement is actually an ingredient of concrete. Concrete is basically a mixture of aggregates and paste. The aggregates are sand and gravel or crushed stone; the paste is water and portland cement. Concrete gets stronger as it gets older. Portland cement is not a brand name, but the generic term for the type of cement used in virtually all concrete, just as stainless is a type of steel and sterling a type of silver.
- Q: Is there a big difference in strength when gluing PVC pipe?
- The PVC glue literally melts the two ends together, the only thing better would be sonic welding them. Epoxy will leech chemicals into the water, the pvc cement is inert once dry, think I'd stick with the pvc cement/glue
- Q: im looking to get true blue Jordan cements but i want to know were to get them, and if there is a difference? thanks to everyone! :)
- The only Jordans that have cement are the III's and the IV's (3's and 4's), and only the 3's have a True Blue colorway, so yes, they should be the same. Typically you can find a pair on eBay. I would also suggest staying away from other websites that sell Jordans, as most are typically fake.
- Q: Do you know anything that can be added to detergent?
- You should generally try to remove any matter before it has a chance to set. But even when the cement is dried, try wiping with a cloth dipped in warm sudsy water to which a few drops of amyl acetate has been added. Rinse well and wipe dry. Cement can occasionally damage the surface of the clothes, so work carefully.
- Q: RECENTLY BOUGHT A HOME AND WHAT APPEARS TO BE AN OUTDOOR TRASH CAN THAT IS MADE OF STONE AND CEMENTED INTO THE GROUND. HOW WOULD I BE ABLE TO REMOVE IT AND HOW FAR IN WOULD IT BE IN THE GROUND. IS THIS COMMON FOR 1950S BUILT HOUSE.
- May have been a fire pit, or even a well since you don't know how deep it is. No tellin how deep it would be without finding the bottom. Either break it up with a sledge hammer or jack hammer, or bury it, or dig it out with a tractor, or with a bunch of guys with shovels. Last method requires a lot of beers. Definitely a custom addition not something common to many homes, unless its some regional thing.
- Q: I've just finished putting the stones onto the liner on my fishpond and a trowel full of cement fell in! When will it be safe to put fish in or will I have to change the water now? I was planning on planting it up first anyhow and letting the plants get established.
- Cement contains large amounts of calcium and magnesium, which act as alkaline buffers when dissolved into water, like a pond. Because of this, you're likely to see your pH skyrocket for quite some time. If there's any way you can get the cement out of the water, that would be best. If not, you're gonna be dealing with an abnormally high pH for some time, which isn't necessarily a bad thing, as Goldfish and Koi will do just fine under such conditions. Regardless, I'd try to flush out as much of the water as possible before getting any fish.
- Q: I was wondering if anyone out there knew the proper procedure for applying 1.5quot; of asphalt to a soil cement subgrade? I dont know if a tack coat is needed or not. Right now we are planning on a fresh broom finish and a single application of asphalt. Its a low use parking lot but I want to make sure we are doing this right.Thanks!
- we do soil-cement base with AC or HMA surface all the time. Never use a tack coat. The thinking is have a slip plane between the two sections. Tack coat would allow the subbase to telegraph cracks up into the AC. The key is to have the right soil-cement mix at optimal moisture. Too much water will result in shrinkage cracks. With only 1.5 inch AC that could be a problem. How did you come up with a soil-cement mix design? How much cement? how thick in your section? good luck! Don the engineer
