Features of Refractory AKZ-85 Alumina Bubble Brick

1.High compressive strength

2.Excellent thermal shock resistance

3.High thermal efficiency of the kiln


Description of Refractory AKZ-85 Alumina Bubble Brick

   alumina bubble brick  refractory brick bricks have high-alumina bauxite powder and refractory clay as raw materials and some inflammable additions, shaped by tamping or extrusion pressing and fired in high-temp tunnel kiln after being dried.

   alumina bubble brick refractory bricks have three brands in accordance with their bulk densities, which are decided by the amount of the inflammable additions.  alumina bubble brick refractory bricks with large bulk density have the features of high mechanical strength and small change of load at a high temperature.


Used  alumina bubble brick Features

Q:what is the difference between concrete and cement and stuco?
cement is one of the products used to produce concrete and stucco. Concrete is used for slabs and sometimes walls and floors of buildings. Stucco is used to coat walls as a finish product.
Q:Why don't famous people get burns when they make handprints in cement?
Umm.... wet cement isn't hot. So they just put their hands in it to make the shape take it out. When it's sunny hot out, yes, cement is hot to the touch can burn you, but wet cement isn't hot enough to burn someone. People have been burned by PROLONGED exposure to wet cement. Celebs others that put their hand/foot prints in cement won't get burned b/c they're only touching it for a few minutes. **YES they wash their hands! Wouldn't you? I'd hate to have cement dried on my hands. So yeah, after they're done putting their prints in cement, they wash their hands.**
Q:why do they put cement on your back teeth when putting braces?
they put it on the fronts of your teeth to glue your brackets on, if they have put it on the 'inside' of your teeth, the flat bit underneath, they shouldt have
Q:How to make cement grout to match brown decomposed granite?
The cement color works but a number of small trials are required to get it just correct. The trials need to be made with an adequate size so the components can be measured accurately and reproduced when the sample color is developed. Even after you think you have the correct color, try your proportions once more with a slightly larger sample to verify the correct ratio has been selected. As you are aware the wet color is different than the dried color. I would start with the cheaper cements and only go up in costs if you are not coming up with the color you want. You may want to try using mixtures of different sand colors if the granite is not getting you to the color you want. This definitely is a trial and error project. You may want to go slightly to the darker side of a match in that as the new grout weathers it will lighten slightly. After the grout weathers a very thin mix of cement and pigment can be mixed up and the joints can be painted with the blend. If bad goes to worse you may want to paint all the joints to make them consistent. I have used Liquid Cement Color by Quikrete which I got at Lowes, it was a bear but finally came up with an acceptable match.
Q:how does cement contribute to greenhouse gases ?
Because cement is derived from limestone. The limestone is quarried certain blocks of this limestone are heated in a lime kiln. The limestone (Calcium carbonate) is reduced to Quick Lime (Calcium Oxide) as a result of the heating of the rock in a kiln driving CO2 off in the process. However, when the cement is mixed with sand to make cement, the addition of water opens up the chemistry to change the calcium oxide to calcium hydroxide. Further than that, the calcium hydroxide, tries to re-incorporate the driven out CO2 back. At the time of hardening, the cement is a different chemical to what it had been at the time the cement was being mixed.
Q:Mixing sand and cement?
First of all, what are you going to use the cement for? Some types of concrete such as Quickcrete don't require sand, only the addition of water.
Q:What are the properties of cement?
Cement should be tested for its following properties: 1. Fineness Fineness, or particle size of portland cement affects rate of hydration, which is responsible for the rate of strength gain. The smaller the particle size, the greater the s
Q:Does a mobile home need a cement pad to sit on?
Most mobile homes are supported on concrete blocks. Shims are then used to assure proper leveling so all the doors and windows open properly.
Q:Surface Bonding Cement mix?
Bonding Cement
Q:Is there a difference between cement and concrete?
The difference between concrete and cement is that concrete contains cement plus sand and gravel. It is the cement that binds the sand and gravel or crushed rock together to form what we call concrete. Concrete then, is more than just cement.
