Ukhonkolo we-aggregate lightweight (LGC), enye yezinto zokwakha ezintsha, ukhonkolo ongasindi owenziwe nge-aggregate engasindi enenqwaba yokuminyana engekho ngaphezu kuka-1900kg/m3, owaziwa nangokuthi ukhonkolo we-porous aggregate lightweight.
Ukhonkolo we-aggregate ongasindi unezici
Ukhonkolo we-lightweight aggregate unezici zesisindo esincane, ukufakwa kahle kokushisa nokumelana nomlilo.Uma kuqhathaniswa nokhonkolo ojwayelekile webanga elifanayo, amandla okucindezela ukhonkolo ohlanganisiwe wesakhiwo angafika ku-70 MPa, anganciphisa isisindo esifile ngaphezu kuka-20-30%.I-structural thermal insulation lightweight aggregate ikhonkrithi iwuhlobo lwentokozo yodonga enokusebenza okuhle kokufakwa kwe-thermal, futhi ukuhanjiswa kwayo okushisayo kungu-0.233-0.523 w / (m * k), okungama-12-33% kuphela alokho kukakhonkolo ojwayelekile.Ukhonkolo we-lightweight aggregate unokusebenza okuhle kokuguquguquka kanye nemodulus enwebekayo ephansi.Ngokuvamile, ukuncipha kanye nokukhasa nakho kukhulu.I-elastic modulus kakhonkolo we-lightweight aggregate ilingana ngokuqondile nokuminyana kwenqwaba namandla.Uma kuncane ukuminyana kwenqwaba namandla ehla, i-elastic modulus iyancipha.Uma kuqhathaniswa nokhonkolo ojwayelekile webanga elifanayo, i-modulus elastic of lightweight aggregate ikhonkrithi icishe ibe ngama-25-65%.
Ukhonkolo we-lightweight aggregate usetshenziswa kabanzi ezakhiweni zezimboni nezabantu kanye namanye amaphrojekthi, anganciphisa isisindo sesakhiwo, athuthukise ukusebenza kokuzamazama komhlaba kwesakhiwo, asindise inani lezinto zokwakha, athuthukise ukusebenza kahle kokuhamba kwengxenye kanye nokuphakamisa, ukunciphisa isisekelo. layisha futhi uthuthukise umsebenzi wokwakha (ukushisa okushisayo nokumelana nomlilo, njll.).Ngakho-ke, ngawo-1960 nawo-1970, ukukhiqizwa kanye nobuchwepheshe bokusebenzisa ukhonkolo we-lightweight aggregate wathuthukiswa ngokushesha, ikakhulukazi ekuqondeni kwesisindo sokukhanya namandla aphezulu.Yayisetshenziswa kakhulu ezakhiweni eziphakeme kakhulu, ezinde kanye nezakhiwo zokuvala, ikakhulukazi ekukhiqizeni amabhulokhi amancane angenalutho ezindongeni.I-China yaqala ukuthuthukisa ukhonkolo we-lightweight aggregate kanye ne-lightweight aggregate kusukela ngeminyaka yawo-1950s.Isetshenziselwa ikakhulukazi amapaneli odonga angaphandle amakhulu kanye namabhulokhi amancane angenalutho ezakhiweni zezimboni kanye nezomphakathi, futhi inani elincane lisetshenziselwa izakhiwo ezithwala imithwalo kanye nezakhiwo ezishisayo zezakhiwo eziphakeme kanye namabhuloho.
Ukhonkolo we-aggregate ongasindi
Izinhlobo eziyinhloko zikakhonkolo we-lightweight aggregate
Ukhonkolo we-aggregate ongasindi uhlukaniswe ngokhonkolo ohlanganisiwe wemvelo ongasindi ngokuya ngezinhlobo ze-aggregate engasindi.Okufana nokhonkolo we-pumice, ukhonkolo we-cinder kanye ne-porous tuff concrete.Ukhonkolo ohlanganisiwe ongasindi wokwenziwa.Okufana nokhonkolo we-clay ceramsite, ukhonkolo we-shale ceramsite, ukhonkolo onwetshiwe we-perlite kanye nokhonkolo we-organic lightweight aggregate.I-Industrial waste lightweight aggregate ukhonkolo.Okufana nokhonkolo we-cinder, ukhonkolo we-ash ceramsite kanye nokhonkolo owandisiwe we-slag bead.
Ngokusho kohlobo lwe-aggregate emihle, ingahlukaniswa ibe: konke ukhonkolo ongasindi.Ukhonkolo we-aggregate ongasindi usebenzisa isihlabathi esilula njengokuhlanganiswa okuhle.Ukhonkolo okhanyayo wesihlabathi.Ukhonkolo we-aggregate ongasindi onengxenye noma sonke isihlabathi esivamile njenge-aggregate emihle.
Ngokusho kokusetshenziswa kwayo, ingahlukaniswa: ukhonkolo ohlanganisiwe oshisayo oshisayo.Ukuminyana kwayo ngobuningi kungaphansi kuka-800 kg/m3, futhi amandla ayo okucindezela angaphansi kuka-5.0 MPa.Isetshenziselwa ikakhulukazi imvilophu yokushisa eshisayo kanye nesakhiwo esishisayo.Ukhonkolo ohlanganisiwe wesakhiwo oshisayo ongasindi.Ukuminyana kwayo ngobuningi kungu-800-1400kg/m3, futhi amandla ayo okucindezela yi-5.0-20.0 MPa.Isetshenziselwa ikakhulukazi izakhiwo zokubiyela eziqinisiwe nezingaqinisiwe.Ukhonkolo we-structural lightweight aggregate.Ukuminyana kwayo ngobuningi kungu-1400-1800 kg / m3, futhi amandla ayo okucindezela yi-15.0-50.0 MPa.Isetshenziselwa ikakhulukazi amalungu athwala imithwalo, amalungu acindezelekile noma izakhiwo.
