Q:Why are clay bricks used when buildings are below zero? Frost heaving, water absorption, or something?
The clay brick has a certain strength, and has better heat insulation and sound insulation performance, and the interior wall of the winter can not appear condensation phenomenon, and the price is low. Although a variety of new wall materials are emerging, clay bricks will still be used as a main material for masonry work in the future
Q:What is the difference between clay brick, glazed tile and brick?
Clay bricks are actually a kind of clay bricks, mainly made of solid bricks! It is a product of continuous optimization of products and upgrading of traditional techniques. Usually made of high quality clay and clay brick clay high temperature firing, using natural clay as main component, quartz and feldspar as aggregate, construction bricks after sintering the formed. The nature of clay brick belongs to low temperature brick, the burning temperature is about 800 degrees Celsius, the water absorption rate is higher, and the general water absorption rate is 8%--10%.
Q:Which is the higher price of concrete solid brick and MU15 fired common brick (non clay brick)?
The price of concrete solid bricks and the price of MU10 bricks are on the same level, and the difference will not exceed two cents a penny. It should be MU15 sinter ordinary brick is more expensive.
Q:Are there any good improvement measures for the always collapse of the previous vaulted tunnel kiln built by refractory bricks?
refractory castable integrally casting
Q:What should be paid attention when the refractory brick kiln furnace reaches a certain service life and will be removed?
Q:cement concrete What kind of cement should be used to manufacture high temperature resistant Kang cement?
Portland slag cement 325 or 425. Use phosphate cement or aluminate cement. Use portland cement. You can also use the fragment and power of waste refractory brick or fireclay brick or aluminous refractory brick.
Q:What is the meaning of the new type of dry rotary kiln refractory brick 620,320?
It should be the length of the turn. I'm not sure if it is right.
Q:How about clay bricks?
Fired ordinary brick is one of the indispensable building materials in production and life, but its quality is not good or bad in the absence of professional equipment. Now to introduce a little trick:According to the main raw materials for clay brick, shale, coal gangue and fly ash brick. Mainly in our local clay brick. According to the compressive strength of weathering resistance of radioactive material and qualified brick, according to the size deviation, appearance quality, efflorescence and lime burst into superior products, first-class products, qualified three quality grades.
Q:What can be applied to the burned refractory brick to resist heat shock?
Acidic refractory material use monox as the main component, among which cilica brick and clay brick are commonly used. Silica brick is silicious product containing monox more than 93%, whose raw materials include silica, waste silica brick scrap and etc. The acid resistance of slag erosion ability is good, and the softening temperature under a fixed load is high. The volume won't shrink after repeated burning, but even a slight expand; but it is vulnerable to the erosion of basic slag, and has low thermal shock resistance. The silica brick is mainly used for coke oven, glass melting furnace, acid hearth furnace and other thermal equipments. Clay brick uses refractory clay as the main raw material, containing 30% to 46% of aluminuum oxide, belong to weakly acidic refractories. It has good heat shock resistance and corrosion stability to acid slag, and it's widely used. Neutral refractory materials use aluminum oxides, chromium hemitrioxides or carbons as the main components. Corundum products containing more than 95% of alumina is a kind of high quality refractory material with wide application.
Q:Blend 12% fireclay and 88% refractory cement. Moderate water and mud are used to pile up firebricks?
Refractory bricks can irectly be liner. Lightweight mullite brick can be used for relatively longer time. If there is no mullite brick, use mud said above for some time, then continue to use by patching up.
