Product Description:

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.)

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.

Q:how do I fix the cement job my husband did?
Paint it or you can try redoing it. Possibly try stamping it and then painting. Hope that helps!
Q:This year, steel, concrete, sand, stone and other building materials prices how, compared with last year is high or low? As long as probably, do not need too much can also,
The current price has been going on for some time, it is likely to be adjusted in the near future, so yo now as soon as possible shot up, up will rise a lot, if the drop will not drop a lot, so I suggest that as long as you have place to place, buy early
Q:how to paint house exterior which is cement plaster?
I have a cement shed and have found masonry paint to be the only type that will last more than a year or two. Wal-mart has a cheap, good masonry paint that can be tinted any color. I've had cheap Wal-mart masonry paint on my shed for 5 years now and there's no sign of a need to repaint, yet,
Q:hurt my knee running on cement...?
KHFDRF DON't RUN ON CEMENT, RUN ON WATER XDDDDDDD That Is Healthier :) OR Your Knee CAPZZZZZZ!!!!! >.< I Am A Doctaaaah! Trust mehhh x
Q:Do I need to install cement board before tiling my shower and floor on a cement floor?
In theory it is, but sometimes the thin-set has a really good bond with the substrate. The hard part is installing the floor tile at the proper and even slope towards the drain. Make sure to use a slip resistant floor tile for the shower. If you use those sheets of 1x1 tiles glued together (Dal-tile) you will have too carefully clean the thinset out of the groutlines before it dries. ( potential big headache) Good luck
Q:Whats best to put on the bottom of an aviary? Rocks? Bark chips? Cement?
Defintely Cement .. or use cement patio blocks if you do not want to deal with mixing cement.. also if you do mix it remove your bird while it cures until its dry.... A solid cement floor is best because its soooooooo easy to clean and disinfect.. also helps wear toe nails down on birds with nails,.. IF you are going to use the blocks..I recommend getting a package of little tykes blue playroom floor tiles.. they are a durable washable foam product... you can cut them to fit and place them over the patio blocks .. this eliminates the cracks between the cement blocks that will catch poop and food and be trouble to keep clean.. Also since they are washable you can take them out and disinfect put right back in.. nd just wipe off in between.. They also provide a cushon.. and the blue color will intrigue your bird and be calming.. Also not slippery if it gets wet. Easier on the feet than gravel. The tiles come in packs of 4 tiles that fit together and cover about 16 sq ft for about 15-20.00 a pack... VERY durable.. I dont recommend any other brand than Little Tykes or Step Two... the other brands are not ok for all pets and also not as durable... we have a lot of experience with these tiles! To get your bird to got o the bottom of the cage using cement or patio blocks with covering The covering alone will invite him down.. birds like clean soft places to hang out... Put a mirror up down there ,,use a bird mirror or a non breakable locker mirror and secure it WELL tot he side of the aviary. Also a shallow pan,..or saucer of water big enough forhte bird to hop aroun d in is good as well... like a plastic base for a plant pot.. never use the ceramic or clay pot bases though.. only plastic clean and put fresh water in daily. She may not go to the bottom now because of the mouse and may know its not ok to do.. You dont want her to the bottom in dirt anyway.. need to have a clean disinfectable surface.. Good Luck Wismom
Q:How do you make cement?
Please be clear. Do you mean how do you make concrete? or how do you make cement? If you mean how do you make concrete, get 1 part cement, 2 parts sand and 4 parts gravel, mix with water until it's a stiff workable consistancy. Wait 24 hours for concrete to become reasonably cured to continue construction.
Q:can you make paint from cement mix?
Yeah that's a nice way to patch the cracks and it will work definitely.
Q:PAINTING Cement statues????HELP?
Is this near/around a pool or water source? Cement must be sealed, then painted. Go to B. Moore paints or Bear paints. Lowes Home center carries both I think. The paint for cement is a special blend that must be used. Can use paint sprayer.
Q:Crack in cement floor of ranch?
I am interested about it. But it is the same questions of me. What's the solution of that.
