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:cement and concrete as composite?
concrete is made up of portland cement and aggregate (sand, gravel and rocks) and you add water in certain ratios.
Q:Do i have to put cement board under tile on the wall?
I would highly recommend doing it right and using cement board. Try to avoid using any type of plywood for a substrate to attach the tile too. Ceramic tiles can be installed directly on drywall, plaster, or if they are in moist areas, onto green drywall or even better cement backer board. Cement backer board is actually made from a fiberglass mesh and Portland cement, so moisture won't bother it at all. It is available in 1/2 and 5/8-inch thick sheets (similar to drywall), and is usually sold in 32 or 36-inch wide panels 5 or 8 feet long. for other information check my source site
Q:How do i remove cement board from the top of ceramic tile?
take a sledge hammer to it.
Q:How could you tell whether a sedimentary rock is cemented with silica (quartz), calcite, or Iron oxide?
Iron oxide cement will colour the rock a distinctive rusty yellow-brown as a result of the significant presence of the minerals haematite and limonite. Calcite cement will leave the rock white but is soft, easily scratched by an iron nail and will fizz with the application of dilute hydrochloric acid. Silica cement will leave the rock glassy colourless, glassy white or rarely, a different colour but also glassy, it will resist being scratched by an iron nail, and will not react with dilute hydrochloric acid. The rock with the silica cement will be most resistant to weathering, and will normally remain as a positive relief feature around the surrounding rocks. The cement in the calcite cemented rock will tend to become dissolved away. The iron oxide cemented rock will be fairly soft but will resist erosion better than the rock with the calcite cement.
Depends what it is you're holding up. The best method is to pour your concrete footer and set a J bolt in the wet cement. When it hardens, set your posts using a Simpson ABU44 for 4'x4 posts, or an ABU66 for 6x6 posts. These construction anchors are available at any lumber yard or home store. Setting the posts in the ground will make them rot, even if they're treated. The anchors will keep them up off the ground.
Q:Is it possible to use regular rubber-cement to work on inner-tube bicycle tire? There is a small rubber-?
Regular Fries
Q:can I make rubber cement at home?
This Site Might Help You. RE: can I make rubber cement at home? I realize it is possible but the only formula I found had gasoline. Are there any other formulas?
Q:I need to relate cement with technology...?
Well, you see, good cement/technology is strong, and much better and more useful things can be bulit upon it, but weak cement/technology doesn't last long, and nothing good can be built on it.
Q:will a trumpet vine grow on a cement wall?
It depends how intact the cement is. If it has little crevices (from being old and disintegrating) the vine might grow, but otherwise, it'd need a trellis or other support on new cement. I DO know that old, unpainted clapboards on a neglected house will make a trumpet vine go NUTS, like the one on a house I once rented, whose landlord was too drunk to do anything like painting, for over 20 years! But the rent was cheap and I enjoyed the many hummingbirds in summer.
Q:How to install cement backer board in a shower?
Install like drywall except use backer board screws. You can seal the joints. If going over a sub-floor you can use an adhesive between the sub-floor and the backer board.
