Lightweight aggregate kongiri (LGC), chimwe chezvinhu zvitsva zvekuvaka, kongiri yakareruka yakagadzirwa neakareruka aggregate ine huzhinji density isingapfuuri 1900kg / m3, inozivikanwawo seporous aggregate lightweight kongiri.

Lightweight aggregate kongiri ine maitiro

Lightweight aggregate kongiri ine hunhu hwehuremu huremu, yakanaka yekupisa yekupisa uye kuramba moto.Kuenzaniswa nekongiri yakajairwa yegiredhi rimwe chete, iyo inomanikidza simba reiyo structural lightweight aggregate kongiri inogona kusvika 70 MPa, iyo inogona kuderedza uremu hwakafa neinodarika 20-30%.Iyo yekumisikidza yekupisa yekupisa lightweight aggregate kongiri imhando yemadziro emadziro ane yakanaka yekupisa insulation performance, uye yayo yekupisa conductivity ndeye 0.233-0.523 w / (m * k), inongori 12-33% yeiyo yekongiri yakajairika.Yakareruka aggregate kongiri ine yakanaka deformation performance uye yakaderera elastic modulus.Kazhinji, shrinkage uye zvinokambaira zvakare zvakakura.Iyo elastic modulus ye lightweight aggregate kongiri yakanangana nehukuru hwayo uye simba.Iyo idiki iyo yakawanda density uye yakaderera simba, inodzika iyo elastic modulus.Kuenzaniswa nekongiri yakajairwa yegiredhi rimwe chete, iyo elastic modulus ye lightweight aggregate kongiri inenge 25-65% yakaderera.

Lightweight aggregate kongiri inoshandiswa zvakanyanya mumaindasitiri uye zvivakwa zvevagari uye mamwe mapurojekiti, anogona kuderedza huremu hwechimiro, kugadzirisa seismic kuita kwechimiro, kuchengetedza huwandu hwezvinhu, kuvandudza kushanda kwechikamu chekufambisa uye kusimudza, kuderedza nheyo. kutakura uye kuvandudza basa rekuvaka (thermal insulation uye kudzivirira moto, nezvimwewo).Naizvozvo, muma1960 nema1970, kugadzirwa uye kushandisa tekinoroji yekongiri isingaremi yakagadziridzwa nekukurumidza, kunyanya munzira yekureruka uye simba rakakura.Yakanga yakashandiswa zvakanyanya mukukwirira kwepamusoro, zvivako zvenguva refu uye zvivako zvekuvhara, kunyanya mukugadzirwa kwezvidhinha zviduku zvemadziro.China yakatanga kugadzira lightweight aggregate uye lightweight aggregate kongiri kubvira kuma1950s.Iyo inonyanya kushandiswa kune yakakura-yekunze ekunze madziro mapaneru uye madiki maburi mabhuroko muzvivakwa zveindasitiri uye zvevagari, uye shoma shoma inoshandiswa kune inotakura-inotakura zvivakwa uye zvinopisa zvivakwa zvekumusoro-kukwira uye mabhiriji zvivakwa.

Mhando huru dze lightweight aggregate kongiri

Lightweight aggregate kongiri yakakamurwa kuita yakasikwa lightweight aggregate kongiri zvichienderana nemhando dzeakareruka aggregate.Senge pumice kongiri, cinder kongiri uye porous tuff kongiri.Artificial lightweight aggregate kongiri.Zvakadai sevhu ceramsite kongiri, shale ceramsite kongiri, yakawedzera perlite kongiri uye organic lightweight aggregate kongiri.Industrial tsvina lightweight aggregate kongiri.Senge cinder kongiri, kubhururuka ash ceramsite kongiri uye yakawedzera slag bead kongiri.

Zvinoenderana nemhando yeaggregate yakanaka, inogona kukamurwa kuita: ese lightweight kongiri.Kongiri yakareruka ichishandisa jecha rakareruka seyakaunganidzwa.Jecha chiedza chekrete.Kongiri yakareruka ine chikamu kana jecha rese rakajairwa seyakaunganidzwa.

Zvinoenderana nekushandiswa kwayo, inogona kukamurwa kuita: thermal insulation lightweight aggregate kongiri.Kuwanda kwayo kwakawanda kuri pasi pe800 kg / m3, uye simba rayo rekumanikidza riri pasi pe5.0 MPa.Inonyanya kushandiswa kune thermal insulation envelope uye thermal chimiro.Structural thermal insulation lightweight aggregate kongiri.Kuwanda kwayo kwe800-1400kg / m3, uye simba rayo rekumanikidza i5.0-20.0 MPa.Inonyanya kushandiswa kune yakasimbiswa uye isina kusimbiswa enclosure zvivakwa.Structural lightweight aggregate kongiri.Kuwanda kwayo kwehuwandu ndeye 1400-1800 kg / m3, uye simba rayo rekumanikidza i15.0-50.0 MPa.Inonyanya kushandiswa kune nhengo dzinotakura mutoro, nhengo dzakasimbiswa kana zvimiro.
