Konkire yopepuka yopepuka (LGC), imodzi mwazinthu zatsopano zomangira, ndi konkriti yopepuka yopangidwa ndi opepuka ophatikizika osapitilira 1900kg / m3, yomwe imadziwikanso kuti porous aggregate lightweight konkire.

Konkire yopepuka yopepuka imakhala ndi mawonekedwe

Konkire yopepuka yopepuka imakhala ndi mawonekedwe a kulemera kopepuka, kutchinjiriza kwamafuta abwino komanso kukana moto.Poyerekeza ndi konkire wamba wa kalasi yemweyo, compressive mphamvu ya structural opepuka akaphatikiza konkire akhoza mpaka 70 MPa, amene akhoza kuchepetsa akufa kulemera ndi oposa 20-30%.The structural matenthedwe kutchinjiriza opepuka aggregate konkire ndi mtundu wa zinthu khoma ndi bwino matenthedwe kutchinjiriza ntchito, ndi matenthedwe madutsidwe ake ndi 0.233-0.523 w / (m * k), amene ndi 12-33% yokha ya konkire wamba.Konkire yopepuka yopepuka imakhala ndi magwiridwe antchito abwino komanso otsika zotanuka modulus.Nthawi zambiri, kutsika ndi kukwawa kumakhalanso kwakukulu.The elastic modulus ya lightweight aggregate konkire imayenderana mwachindunji ndi kuchuluka kwake komanso mphamvu zake.Zing'onozing'ono kachulukidwe kachulukidwe ndi kutsika kwa mphamvu, kutsika kwa modulus yotanuka.Poyerekeza ndi konkire wamba wa kalasi yomweyo, zotanuka modulus opepuka aggregate konkire ndi za 25-65% m'munsi.

Konkire yopepuka yopepuka imagwiritsidwa ntchito kwambiri m'mafakitale ndi nyumba zachitukuko ndi ntchito zina, zomwe zimatha kuchepetsa kulemera kwa kapangidwe kake, kukonza magwiridwe antchito a chivomezicho, kupulumutsa kuchuluka kwazinthu, kukonza magwiridwe antchito agawo ndi kukweza, kuchepetsa maziko. kunyamula ndi kukonza ntchito yomanga (kuteteza kutentha ndi kukana moto, etc.).Choncho, m'zaka za m'ma 1960 ndi 1970, kupanga ndi kugwiritsa ntchito teknoloji ya konkire yopepuka yopepuka idakula mwachangu, makamaka potengera kulemera komanso mphamvu yayikulu.Anagwiritsidwa ntchito kwambiri m'mapangidwe apamwamba, aatali komanso otsekera, makamaka popanga timatabwa tating'ono ta makoma.China idayamba kupanga konkriti yopepuka komanso yopepuka kuyambira 1950s.Amagwiritsidwa ntchito makamaka pamapangidwe akuluakulu akunja akunja ndi mazenera ang'onoang'ono ang'onoang'ono m'nyumba za mafakitale ndi za anthu, ndipo pang'ono amagwiritsidwa ntchito popanga katundu ndi nyumba zotentha za nyumba zapamwamba ndi za mlatho.

Konkire yopepuka yophatikizika

Main mitundu ya opepuka aggregate konkire

Opepuka akaphatikiza konkire amagawidwa mu chilengedwe opepuka akaphatikiza konkire malinga ndi mitundu ya opepuka akaphatikiza.Monga pumice konkire, cinder konkire ndi porous tuff konkire.Zopanga zopepuka zophatikizika konkire.Monga dongo ceramsite konkire, shale ceramsite konkire, kukodzedwa perlite konkire ndi organic opepuka aggregate konkire.Industrial zinyalala opepuka akaphatikiza konkire.Monga cinder konkire, kuwuluka phulusa ceramsite konkire ndi kukodzedwa slag mkanda konkire.

Malinga ndi mtundu wa aggregate yabwino, imatha kugawidwa kukhala: konkire yonse yopepuka.Konkire yopepuka yophatikizika pogwiritsa ntchito mchenga wopepuka ngati kophatikiza bwino.Mchenga kuwala konkire.Opepuka akaphatikiza konkire ndi mbali kapena onse mchenga wamba monga chabwino akaphatikiza.

Malinga ndi ntchito yake, akhoza kugawidwa mu: matenthedwe kutchinjiriza opepuka aggregate konkire.Kachulukidwe wake wochuluka ndi wochepera 800 kg / m3, ndipo mphamvu yake yopondereza ndi yochepera 5.0 MPa.Amagwiritsidwa ntchito makamaka pa envelopu yotentha yotentha komanso kapangidwe kawo.Structural matenthedwe kutchinjiriza opepuka aggregate konkire.Kuchulukana kwake ndi 800-1400kg / m3, ndipo mphamvu yake yopondereza ndi 5.0-20.0 MPa.Amagwiritsidwa ntchito makamaka pomanga zolimba komanso zosakhazikika.Structural lightweight aggregate konkire.Kuchulukana kwake ndi 1400-1800 kg / m3, ndipo mphamvu yake yopondereza ndi 15.0-50.0 MPa.Amagwiritsidwa ntchito makamaka kwa mamembala onyamula katundu, mamembala opanikizika kapena zomanga.
