Clay bricks and dense clay bricks are different refractory bricks, the difference is in porosity. The porosity of clay bricks is about 26%. The aluminum content is 40%-55%, and the bulk density is 2.1-2.15g/cm3. The porosity of fine clay bricks is less than 18%, and the bulk Cufnaanta ayaa ka weyn 2 {{10 {10} 2G / cm {{{} 3. Porsity Polds, oo xoogga iska caabbinta.
Dhoobada dhoobada dhoobada ah iyo dhoobada cufan waxay leeyihiin dhibco kala duwan, noocyo kala duwan oo ah alaabo cayriin, cufnaanno kaladuwan, oo u dhexeeya dhowr boqol yuan {0} ah oo ah mabda'a, qiimaha sare ee {{1 {} {{1}
Beerta dhoobada ah guud ahaan waxaa loo isticmaali karaa foornooyinka warshadaha ee heerkulka ka hooseeya 1250 shahaado, geedaha qarashka leh, iyo qaybaha kuleylka ah ee . ah, si naxariis ah . inta badan waa porosity in ka badan 12% waxaa loo isticmaalaa nabarrada biraha ee aan la soo koobi karin. kilns {{5}
Dhaqanka ceyriinka cayrinta iyo semi-dhammeysey geesaha dhoobada dhoobada dhoobada dhoobo ah ayaa asal ahaan isku mid ah, iyo saamiga dahabiga ah ee 'Coke Gemstones' waa {{} . xinjirka dhoobada dhoobada ah, halka left {{} {}, halka levery dhoobo . ah leyl cufan wax yar yaree inta lagu guda jiro cafiska, kaas oo kordhiya cufnaanta weyn oo waxay yareysaa porosity {{5}
Waxqabadka Ther-ka ee naxdinta leh ee lebenkii dhoobada dhoobada dhoobada dhoobada dhoobada ah, oo waxay leedahay faa'iidooyin xoog sare oo xoog sare leh, adag, iska caabin heerkul sare ah, iska caabbinta heerkulka iyo iska caabbinta.
Midabka lebenkii dhoobada ah waa huruud khafiif ah, midabka muuqaalka ah ee lebenkii cufan waa casaan {{0} ka dib markii qaybta dhoobada dhoobada ah ay tahay, laakiin ka dib qaybta dhoobada cad ee lefstone {{1} marka loo eego intaa waxaa dheer, waxaa jira shahaado shabakad ah Dildilaac ., oo, hoos udhaca caabbinta iyo caabbinta dillaaca ee lebenkii dhoobada qadka dheer ayaa hagaajinaya .
