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 was in sally's the other day and i saw hair cement and i read the directions and stuff but i still dont understand what it is like does it wash out and like is it like dye?
- It's like a hair gel
- Q: Hello All, I have had fixed dark brown tiles on my bathroom floor, however the guys did a bad job at it, and i can see the white cement in beween the tiles.. and its actually making the whole pattern look bad.. I was wondering if there was any way I could kind of colour the cement filling in between the tiles so that it blends with the colour of the tiles... ?Also any suggestions for removal of cement stains off these tiles? PLEASE Help, i am really in a mess here.
- If as you say, the the job is of a poor finish you can rake out the joints using a flat head screwdriver when this has been done thoroughly clean the surface. You can purchase coloured waterproof grout from most DIY or hardware stores. If the grout is in powder form then you will need to put water into a container first, then add the powder stirring as you add it until it is of a thick creamy cosistency. Pour this over the tiles and using a rubber squeegy (the type you would use for cleaning your windows) spread the mix and ensure it goes into each tile joint. If it dries quickly then deal with it approximately 1 sq yard at a time. using a sponge and a bucket of water, clean off the excess grout and rub dry with a clean cloth. This should give you a good finish! As for the removing the cement stains this can be removed using a paint scraper and a scouring pad. Note this should be done prior to you preparing the above for grouting. Good luck.
- Q: I bought a cement ladder ( not edible ) yesterday. today i put the cement ladder in the cage but he starts nibbleing the cement and tasting it ( i can hear the crunch flavor in his beak an swallowing it ) . HELP WHAT SHOULD I DO!!!!!!!!!???
- he needs grit, it should be ok though because birds dont have teeth, they eat dirt grit and in your case cement to put in their crops (roughly the bottom of their necks) to grind up food. Go to the pet shop and buy some grit for your bird. also a cuttle fish bone for calcium and to keep its beak from overgrowing. x oh and i see the first answer says to use sandpaper perches, dont Because it hurts their feet and makes them dry, just use birds sandpaper to cover the bottom of the cage. not standard sandpaper, stuff from the pet shop.
- Q: Our pool liner ripped!! our pool is custom 11ft deep. we drained the pool we are removing the water from behind the liner. We are trying desperatly to make this liner last one more summer! Of course it ripped down at the 11 ft area. but the rip only runs along the top edge of the lip that snaps into the metal ring around the pool. I came up with the idea of using rubber cement to cement the ripped liner to the steel wall. Is this possible?? we just can't shell out 3,700.00 for a liner right now and its HOT the kids are driving us insane to try something ANYTHING does anyone have anybetter ideas?? we are open to any ideas! thanks
- They make vinyl patches that could well work in this case. Have you tried a pool store? As I under stand it you would just put the patch over the rip using heat or glue or both you get a pretty good patch. By that I mean, if the rest of the liner is in good shape you could get years of use from it.
- Q: yeah. I was wondering why tires on cement have such good friction while other materials do not.
- because cement is not as compactly put togehter as other materials such as gravel. because there is space between the concrete( hard to detect with naked eye) the tire dont as easily roll over the surface creating friction. hope it helps.
- Q: in the dream, i got a job helping this old lady. She showed me under her counter and her daughter was kept under there because she had a mole, like the animal, growing out of her stomache. The daughter had babies and they were covered in cement. There was also a cement covered chicken. The old lady showed me a video of the babies getting baptized but it was actually a priest holding them up the putting them in a bath tub of cement. Later on I told the police and there was something weird, and then it went off where my friend and me were at a phone booth for a few hours so she could get cheap plane tickets. It was really really weird, any idea's what this could mean?
- Stop huffing paint, that's what it means.
- Q: i need to cement some blocks in my my garden any help
- The simple way would be to buy mason mix and all you got to ad is water. My understanding is you already got sand, now you need type c cement and water. use your wheelbarrow to mix your mortar in and use on every 4 shovels of sand one shovel of cement. take a rake or a hoe to mix both ingredients well while they are still dry, now ad some water not too much and mix it some more, repeat adding water until you get a pudding like paste. Check with your trowel the mixture and make sure will stick to it if you turn it upside down. If it is runny and won't stick mix an additional shovel of cement into your mix. If you ad by mistake to much water simply ad sand to the mix . Your goal is to make it stick to your trowel than it is good to better your bricks or blocks.
- Q: I would like to build a wall and I understand that just fine however the floor is cement so I obviousy can't just throw some nailes into it. Any tips would be appreciated it will be in my basement
- Actually, you could just use cement nails, but a better choice is to drill holes where you are going to fasten the wall to the floor. In these holes you hammer a sleeve. When you drive a screw into this spacer, it holds it in place. Any Home Depot type company will have these drills and cement screw/sleeve. I have had permanent walls done up on cement in this way.
- Q: Was cement invented by the good guys or the bad guys?
- Cement does not normally occur in nature, so you could reasonably say the technique of artificially combining inert sand with a binder like quicklime is an invention. It was invented by the ancient Mesopotamians in the 3rd millenium BC. It's a tough call to say from this distance whether they were mostly good or bad guys, but if you read up on them and it turns out they kept slaves or practiced human sacrifice then I'd reckon they were bad by our standards.
- Q: i want to practice track on the streets and i want to break in track shoes with spikes
- no you really shouldn't, i suppose you could but one it wears them down, two it feels weird and you cant run as well. use them on a track or grass/dirt roads
