high alumina Cement

Aluminate cement products for the alumina content of 50% -60% of the cement matrix.

Aluminate cement CA-50 series products, the main mineral phase composition of CA-phase (a calcium aluminum acid. 2 aluminum acid a calcium). Therefore, not only products with a relatively high temperature use of performance, but at the same time have a reasonable and stable hydration of the performance, rapid growth in outstanding physical strength properties

The company's production of aluminate cement CA-50 series based on the development of cement hydration and the relative intensity of the physical strength to be the value of the product into different grades, so that customers according to their demand for the product and the use of conditions to choose. Meanwhile, through the production process of the optimization of product performance so that it can adapt to both the monolithic refractories different construction methods (such as: casting, injection), also can meet a variety of castable formula system, such as: the traditional combination of high alumina cement castables and medium-cement castables, the performance of the construction made by the different requirements.

This series of product does not contain any additives to ensure product suitability and stability.

Q: what means by special cement ? Example ? website ?: *Special Cements: It is used for a special application and are having special additives like some minerals. Example: 1.Rapid-setting High-strength Sulphoaluminate Cement, 2.Aluminate Cement, 3.White Cement 4.Special Inorganic Cements. 5.Anti acid cement (acid resistant cement) *** Polymethylmethacrylate (PMMA), has been used to reconstruct bone during surgery for at least 20 years.

Q: i know it's by adding water but what happenes to it tom make it turn into cement?Thank you!: Cement hardens when mixed with water because of a complex chemical reaction that takes place. So the short answer is chemical reaction. Cement powder is mixed with aggregate, sand, and water ot make concrete. Roads, driveways, sidewalk, etc. are all made out of concrete. Cement is one of the ingredients in concrete. Cement is the ingredient that makes concrete get hard. You want the concrete to cure not dry. You must keep it moist for the curing (chemical reaction) to complete.

Q: The fence is typical 47 inch wire field fencing. I am putting it on a one acre lot with the post being placed every 15 feet. I am using landscaping post as they are cheaper then regular post and i have worked with them before on my stockade fencing with no problem. I am installing two 10 foot farm gates which are 1 and 3/4 inch tubular steel. I will be using 4x4 pressure treated post on the 4 corners and the post holding the gates.I need to know how much concrete i would need for the 60 land scaping post and the 6 4x4 post. I am figuring one 60 pound bag of cement (the kind you get for about $2.50 a bag) for every two landscaping post and one full bag for each of the 4x4 post giving me a total of 36 bags. I am presently not planning on adding any stones to the mix, just water.The post will be 2 feet in the ground and 6 feet above. Barb wire across the top.Does this sound right or am way off on how many post will do one bag? The total feet of fencing is 900 feet.: Cement is good, but we like to use crushed stone on all our fences that we install (if it is wood). Reason being, the crushed stone allows the water to drain away from the wood and you get less rot over the course of time than you would with cement. Also, once you set the post in cement, it is a royal pain to remove/adjust. Not to mention the ease of having buckets of crushed stone instead of having to mix cement and all the hastle which goes along with that. just a thought

Q: Need' to get 20 cement blocks home. How many [weight wise] can I put in the back of a PT Cruiser.? About how much does a 'Nellis' type cement block weight?: I just bought an '06 PT Cruiser and I love it. People think it's small inside, but in all truth, there's quite a bit of room - front and back. You can't say it's small inside just by looking inside it - you have to really ride in it to notice the room. It rides very smooth and gives you a great, comfy ride. You also hear very little outside road noise as compared to a convertible. I'm saddened to hear that they're discontinuing it - I like mine. :D

Q: why does cement not become soft when wet after it has dried?: Cement is a chemical reaction with water. The water only makes it feel wet when yo are first mixing it. But the water is actually reacting with the calcium oxide in the cement powder which turns rock hard after the reaction takes places.

Q: Start a new type of cement products building materials company, I would like to ask after the environmental protection project, qualification and related procedures can be issued directly can not how to take the procedure: If the Pearl River Delta and the like, he is not approved is not approved, the money is useless, he will not for you a small project and back pot You did not report EIA, EPA will not go to the scene to see rotten It is clear that Jun is a layman EIA price is determined by the local market competition, with that pricing is not the relationship between the penny It is best to find the local strength of the intermediary or environmental companies to help you follow up

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: I just poured cement anchors for a swingset. Eventually, I will cover the entire area with a tarp and then 3-4 inches of pea gravel. I'm wondering how long I should wait, to do this. Should I wait a week or so for the cement to cure more, before I cover it up? Or can I lay down the tarp immediately?: You can cover it when ever you want. The cement is not drying, it is curing. The water does not evaporate from it, but there is a chemical reaction between the water, portland cement, and other components that make it harden to full strength. So have at it, just don't expect it to be at full strength till it finishes curing.

Q: How is cement used to make concrete?What are the principle types of concrete and how are they made?: Shouldn't you be asking this question in (homework help)

Q: if i filled a balloon with air, covered it with cement, waited a few hours, deflated the balloon, pulled the balloon out, could i create a hollow cement sphere?????: There are two things you mention that will lead you to an answer of No. First, in order to pull out the balloon, you will need a hole and strictly speaking, you will not have a true sphere because of the hole. Overlooking that little problem is a more significant one. A few hours is not long enough. Cement takes a very long time to achieve its maximum strength. When cement is used in construction, it is left to harden for at least 7 days before any weight is placed on it. Ideally, you should wait about 30 days before expecting anything made of cement to sustain a significant load. There is another problem that you did not mention. That is that cement can be very strong in compression but will never be as strong in tension. That is why any cement structure that has to support anything is usually reinforced with steel. Will your cement balloon float? It could, if you size it properly and fill it with helium or hydrogen.
