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: we just put wooden post into the ground and put cement around it a couple of days ago, and we heard that cement could eat the wood, and we did not put plastic on the end of them.
- If you sloped the cement away from pole to let water run off ,your grandchildren will see them out, in other words, a bloody long time. I found that after a week the cement seems to shrink slightly around the top ,you squeeze silicone sealer between cement and timber, cause water will rot the pole before cement, but still a bloody long time.....So sit down with a coldie and enjoy your new fence or whatever without a worry.
- Q: Cement grinding aids are chemical or building materials ah what is based on ah?
- It should be said that not building materials
- Q: I am makeing something for my mother and I wanted to set a picture in a cement stepping stone. If I can't do it with cement, then I was thinking of plaster of paris. Now that I want to do this project, I don't know how to go about doing this. HELP!!!
- Let's see... I think plaster might be too fragile. You know, you can mix equal parts of plaster and cement. It'll set quick enough, and be strong enough. Because, cement can take days to set properly. With the mix, half an hour, tops. The picture alone will probably get ruined, like putting paper in water. I'd keep it in a frame, or glue it in later. I'd leave a space in the stepping stone so when I put the picture in, it'd lie flat, not on top of the stone. Inset. Then I'd cover it with plexi-glass. A lot of hardware or craft stores will sell little sheets. In fact, maybe I'd just make the stepping stone into one large picture frame. I'd use something of equal size and make sure that I used a lot of release (wax, soap, grease) and some pieces of wood to make a mold, where you'll pour in the mix. Make sure you coat anything (table, boards of wood) in release that you don't want stuck to the mix. Then it's just a bit of thinking and testing to find what will work.

- Decrease in water/cement ratio will result in difficulty in obtaining smooth finished surface. Increase in water/cement ratio will result in(3) Decrease in strength.
- Q: We installed bamboo fencing on our garden to add height to our outdoor wall. when rain falls, the poles get filled with water. We thought of placing an improvised metal roofing on it as what we see on other houses' fencing but we thought it will make the fence's look a lot awful. So we decided to fill each poles with concrete. will this do harm to the quality of the poles? Is it wrong to fill bamboo poles with cement?
- filling them with cement or like material will keep any moisture trapped in there and also weight them down. fill them with lightweight expanding foam and after it is completely dry you can cut away the excess so it looks the same
- Q: and also does the cement have an affect on the water quality, such as ph, hardness...etc?and also if i do build it out of cement, do i still have to put down a pond liner?and also does anyone have any advice, or info on building a pond out of cement?THANK YOU
- Cement-by which I presume you mean concrete, is fine for building a pond. It Will have an effect on the ph of the water. Cement is alkaline so the lime content would be very harmful to fish and aquatic life in the short term. Eventually it would become neutral but you would need to waterproof it with something anyrate which would keep the water away from contact with the cement. You can use bitumen which you paint on or a sheet of strong plastic is often enough.. Dig out the shape you want first and then shovel the concrete into it but if the sides are steep then you will have to make the concrete very dry to prevent the concrete running back into the bottom. You can always then give a thin coat of wetter cement to the sides later if you prefer
- Q: I want to do building business business sand cement stones. The (Need to add) What equipment needs to invest about how many predecessors advice about how business can do well.
- Transport equipment, loading equipment, operating space, inventory. Forklift, of course, is a falconating charcoal ghosts and gambling ghosts and ghetto ghosts you know how to make it!
- Q: I would like to ask: inside the building materials, often mentioned water-based products, cement-based products What is the meaning? You prawn help solve ~ ~ ~! The The 3Q more
- And 'water-based' products corresponding to the 'oil-based' products, mainly in the coatings, waterproofing agents, adhesives and other liquid products have this distinction. Oil-based products in the use of chemical solvents, solvent evaporation after use, odor, and may even contain harmful health formaldehyde, benzene and other substances, so oil-based products are considered not environmentally friendly. Water-based products because the volatile out of the water, so do not produce tragic trace of the main tube fly 攮 read homecoming, ridicule, harmless to the environment. The cementitious material is cemented in cement to distinguish it from lime, gypsum, magnesium oxychloride or organic materials as a cementitious material.
- Q: The cement board now has holes, tons of marks, glue, bad wallpaper you name it. Can I place drywall over it in order paint it? I plan to replace the tile from the waist down but on the upper wall I want to paint. Any tips are appreciated.
- As long as the cement board is not in the tub surround or shower area, you can replace it with blue (mold and water resistant (preferred)), or green (water resistant) drywall. Never use standard drywall in a bathroom or kitchen. The moisture in these two areas can create a mold problem. I recommend you remove the cement board rather than putting the drywall over it. Any electrical outlet or switch junction boxes may have to be repositioned in order to get the switches and receptacles to sit flush with the wall. The other issue is that the closed in pocket between the cement board and drywall could be a moisture trap, especially in the bathroom. That's just asking for trouble. Finally, unless you have experience taping and mudding (finishing) drywall, I suggest you hire a professional to do this for you.
- Q: i'm deciding on either white cement 4s 2012, or stealth 3s. i already have military blues but im starting not to like them, however i am not selling them. I reallydnt want another pair of 4s but the white cements are probably one of my favorite jordans. Which should i get?
- Get the white cements
