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,which early strength is 5-6 times than that of OPC; if used in 0-20 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.

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.

Q:how to start new cement industry?
A new cement industry or a new cement company? Are you actually going to be dealing in cement or is it actually going to be some sort of concrete product manufacturing? It is common for people who are not familiar with concrete to call concrete cement which is only the binder for the final product.
Q:Describe how concrete is made from cement?
Concrete contains: * Portland Cement - Sintered limestone, clay, and gypsum * Aggregate - filler such as rocks and sand * Additives - often nylon fibers, or chemicals, to affect strength or cure time * Reinforcement - optional, steel cable, wire, mesh, or bars. * Water - which binds the cement molecules chemically * Carbon dioxide - joins in from the air to help form crystals in the mixture. Concrete is made by: * Preparing the mold or form, such as laying boards, flattening soil, stamping a shape into sheet metal, or just digging a round hole. * Laying the reinforcements, such as a grid of textured steel bar, or maybe nothing at all. * Mixing the rest of the ingredients in a hopper large enough to handle the weight * Pouring the mud/slurry into the form * Packing, shoveling, or vibrating to help settle the mud and remove trapped air. Typical concrete may set (harden) in 30 minutes to a few hours. Cure time is longer (maximum strength) and typically takes from a few days to a month. Cure may be incomplete if the cement is allowed to dry out, so it's common to cover concrete with plastic, sealants, sprinklers, or use chemicals mixed in to help retain moisture during the cure. These same procedures happen, whether it's a bag of quick-crete poured into a hole with a mailbox post, or whether it's a million ton footing poured in a single session. A great way to see this in action is to look for road construction, or bridge construction.
Q:Does lenolium stick to cement?
Sure it will stick, just make sure you use the right type of adhesive.
Q:How do you calculate how much cement is needed for a volume of concrete?
well, depending on the water:cement ratio that u desired to have.
Q:uncomfortable slab of cement on my braces..?
The point of the cement on your molars are that the teeth don't meet! Your orthodontist did that for a reason! I had those on when I first got my braces, and one did end up falling off but they put more on later. I think the cement may be so that your teeth don't grind together or that the braces do not touch. It could also be that they didn't want you chewing down on the elastics if you have any. Don't worry! In a couple of days you will be able to chew normal and everything will feel fine! Stick it out, it will be worth it.
Q:How much cement does it take to fill 401 cubic in?
I think there needs to be more data. For example, how much volume does one pound of cement fill....or something like that in order to complete the equation.
Q:Is there a solvent for plumbers cement?
Yes, it is a type of pipe dope (thread sealer). There are joint and gasket sealers sold world-wide. Hercules, Tap-con, Dope Pro and etc. all have sold this type of product. The older ones ALWAYS dried to a cement like seal. There is no solvent available for this issue. Unfortunately, if an old version was used, you only have 2 options available. 1. You can use your torch to heat and loosen the product form the valve. The real problem here is that if you are using the type of valve you posted in the picture, you run the great risk of permanently ruining the valve anyway. 2. Simply cut behind the valve and solder in a new one. Use the tape thread sealer and off you go. This is BY FAR the best option. Write to me if you have any questions. I'll be happy to help anytime. EDIT: Bill, Here's the issue. The pipe dope usually remains somewhat flexible for a long time. However, penetrating oil will not do the job. If you have a Monkey wrench, vice grip or a slip wrench (aka Channel) you have a good chance. You can heat the joint with a hair dryer. This may soften it enough. Hold the valve firm, with one of the above in one hand, and loosen the nut with the other. Vice grips work best to hold the valve steady. There are other options if this fails to work for you. One is to cut the feed line, and splice a new one on (using compresion fittings or a pipe splice). The best option is to turn the water off to the valve, cut the pipe below/behind it, and solder a new one on. If you are worried about soldering, buy a tool and die thread maker (inexpensive), create new thread and screw a new valve into place. If you are inexperienced at this, the soldering option is best. Vote for me, and feel free to write again should you have any questions. The return mail option did not work.
Q:why do tires on cement have such good fiction?
Concrete is a rough surface, hence the high friction coefficient.
Q:If our new house already has tile floors, will it automatically have cement board?
One poster is right you can t really be able to tell just by looking. If there is forced air heat, lift a register and look whats between the tile and subfloor. Over the years I have seen it all .. There are so many ways to install tile , some proper and some not.. I ve seen many types and thicknesses of plywood., cement board(s) properly and improperly used and even many good installers will do a mud job. A proper mud job is the absolute best way to do tile.. Sealer will cost around 80/100 $ a gallon.And you ll need several gallons for that amount.. Have your installer look at the job. A good installer will be able to determine what was used.. Travertine is a beautifull stone and when properly sealed and maintained will last a life time. This type of stone will start at 5$ a s/f and go up from there.Thinsets go for about 13/15$ a bag and cover about 70/80 s/f per bag. Cement board is 10$ a sheet and covers only 15 s/f per sheet. Grout is about 10$ a bag but tile thickness will determine how many you need.. If you have a slab flooring no extra subflooring will be needed. Your tile guy will give you the exact amounts you will need. Ask for a quanity discount , you d better get it for that anount of material. Any questions you can e mail me through my avatar and check my qualifications there. GL
Q:How does cement work?
When water is added it starts a process beginning with the formation of short hexagonal crystals. it is this process of crystal formation which begins the setting process and usually is substantially complete after 24 hours. However, the crystals continue to form and fill up the spaces for weeks and even months as long as the cement is not allowed to dry out. When mixing cement it is recommended to keep it wet for at least 3 days, when it reaches maybe 80% of its final strength, but a week to ten days is better. Cement will continue to harden for several years. The strongest cement you can get is that which sets up underwater and is never allowed to dry out.
