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: Just for kicks I tried to live up to my name a few days ago. So, I threw a party, and for the grand finale I tried to pick up one of those cement parking curbs and give it a good heave- ho. Long story short- after 3 of my buddies lifted the dang thing off of me, they drove me to the hospital... and my back aint doing so good. Stupid me for trying, or a man of his word?
- I'm going to go wayyyy out on a limb here and guess that cement curbs are heavy... BECAUSE THEY'RE MADE OUT OF CEMENT! I won't be as harsh to say that you are stupid - we are all capable of making poor decisions... and that was one. I do hope your back gets better, though.
- Q: the big pieces came from a old cement gold fish pond in my yard .
- Sledge hammer - cheapest and hardest way; be sure to use eye protection and cover any near by windows Jackhammer - pretty demanding physically Rent a bobcat - easiest, but costliest; if there is a lot of cement, it will help to move around the broken pieces afterward
- Q: is is located in looc, malabuyoc, cebu, philippines .. it is under the yuchengco group of companies .
- South Western Cement Corporation c/o 3883 First Street. Forest Hills, Banawa, Cebu CIty, Malabuyoc Yes it is part of the Yuchengco group. Sorry could not find tel nos.

- Q: Thought to be Lafarge cement, after 3 or 4 months should it start to deteriorate? If so why is this?
- A bit vague, but in general no cement should start to deteriorate so quickly. Was the reinforcement rusty? That will cause spalling (bursting of the concrete) Also a bad mix or improper curing (curing can be immensely important in some applications). There are also any number of chemicals which will deteriorate concrete and many of them are found right there in the ground, but this should take years to occur. If this came out of a Lafarge truck, there is always the possibility that you got a mix intended for someone else (this happens more often than many realize) There really is no excuse for cement to fail so quickly, if this was a pro job I'd have them back ASAP. If it was a personal job, check your delivery docket and if all is well, call the batch plant and get one of the concrete guys out there to take a look. It's rare, but sometimes you just get a bad batch.
- Q: Tell me about PVC cement glue?
- The cement should be applied on both the pipe and the inside of the fitting. Primer should be used to get the best results. Once both surfaces have glue applied, slip together and twist 1/4 turn while pushing inwards. Hold for 5 seconds and your done. CPVC needs a different type glue that is made especially for it. CPVC is used for hot water lines while PVC is for cold water and drainage lines. Getting it off your hands is a chore. Use the brush that is usually contained in the can lid.

- Q: White cement accidentally wash clothes how to do, how can we remove, thank you
- And then slowly rubbing, rinse with water several times, do not add bleach, bleach will make the clothes lighter color
- Q: need to glue lattice frame work together to fit inside wall opening
- PVC cement, is basically a solvent that melts the materials, and you join them together and give a small 1/4 twist to bind them. If its the same type of plastic, (pvc), then it should work. But, remember this, each piece is inserted in the other for a good bind... While your lattice work is not going to be inserted, just melted together, and that wont make a good bond as regular pcv pipe. I wish you well.. Jesse
