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.

4. Water conservancy facilities and offshore projects.

5. Bridge and road construction.

6. Cement products and prefabricated components.

7.  Industrial and civil engineering.

 

Package and storage:

bulk and weave package with membrane, 50kg per bag, conservation in cool and dry place, prevent wet.

Q:how to set up a cement slab?
Preparation for pouring a cement (concrete) slab would include: 1.digging in the earth to leveling the area and provide enough space for the slab. A standard for my area is 4 of concrete with 6x6 wire or 6 of concrete without reinforcement. The more uniform the area the greater is the ability to predict the size of the required pour. 2. setting up forms While I have seen expansion joints thrown into wet concrete a better job is when the expansion joint is placed against a subdivision of the slab. 3. pour the concrete making sure that any wire mesh reinforcement is not touching the earth. 4 screeding off the concrete 5 pulling up forms and any additional finishing. including stamping, coloring or other texturing This is a very searchable topic.
Q:joining cement backerboard with drywall?
use the same nylon joint tape and the thinset that you used on the other joints of the backerboard. aplly the thinset as smooth as possible. when it dry you can apply a layer of drywall joint compound over the thinset. you dont have to over lap the tile over the joint. after the drywall compound dries, sand and finish like the rest of the drywall
Q:Is the cement industry in the stock a separate plate? Or part of the other plate?
Now can be considered a sub-section, there are several leading enterprises
Q:how to determine the amount of silica in cement?
The amount of silica would normally be measured in the raw mix before it is put into a cement kiln otherwise its too late to modify it. Its done by X-ray fluorescence
Q:Is cement expensive?
Labour? Yes Cement? Not so much May be better off digging and evening the ground yourself and buying some large concrete slabs and placing them there yourself. Best of luck Lew
Q:How to identify the quality of cement and sand in home improvement?
A * A * A = A3 A: It is considered A3cm3 (dm3.m3). 3 to 1 stirring this how to say that you are used to grinding the floor, or Fenqiang, or why? The
Q:Does anyone that had braces when they were younger still have cement on their teeth?
Nope. i've got have been given had braces for over a month and after eating soda, now no longer some thing befell. no count if it somewhat is on your mouth, i'm useful it somewhat is not poisonous hun. i could propose now no longer eating soda as a lot, regardless of the indisputable certainty that, simply by certainty soda motives cavities easily and a hollow section with braces could in elementary words reason the orthodontist to could desire to save them on a lot a lot longer. it somewhat is greater useful to in elementary words drink water or yet yet another helthy dtink as nicely, as soda is somewhat volatile do to the severe fructose corn syrup and all the flexibility.
Q:Cement truck or quikrete?
The third option is mixing up your own concrete from Portland Cement, gravel and sand aggregate. That will be much cheaper than Quikrete, and probably a bit cheaper than a ready-mix truck. It's really the only way to go if truck access to the site is poor, or if you don't want to tear up the adjacent grass too much.
Q:limestone -> cement, concrete and glass?
the generic term cement simply means binder or glue; hydraulic cements are those which bind and harden in the presence of water. Early construction cements were usually clays mixed with an aerated volcanic rock called pumice; later mixtures included chalk (a high grade limestone composed of coccolithic (spherical stones) carbonate structures. What we commonly call cement and mostly use in construction and landscaping today is a type of cement called Portland cement, which was accredited to Joseph Aspdin in 1824; a mixture of ground (often low grade, or impure) limestone and clays containing aluminium sulfates. Gypsum (hydrous calcium sulfate) may be added to the mixture if more sulfates are needed. Concrete is an artificial conglomerate (in geology, a conglomerate is a rock made up of often metal-rich stones set in a matrix of sand and fine clays) where the binding matrix is composed of (usually) Portland cement and clean sand, and stones (commonly called gravel or road metal); without the stones, the mixture can be a mortar (used to bed and bind bricks or blocks) or a render (a thick paste used to dress bricks and blocks). Glass is commonly composed of melted quartz sand (silica); limestone is added to the silica to prevent recrystallisation when it cools.
Q:What are the ingredients of cement?
I hate to link to Wikipedia, but a proper answer is rather complex and the article there is actually rather complete and accurate.
