Kugeza ubu Imiterere yubushakashatsi bwa Fly Ash muri Engineering Engineering

Gukoresha ivu ryisazi mukibanza cya kaburimbo byibanda cyane mubice bibiri: ivu ryisazi (lime na fly ash) ibikoresho bihamye hamwe na sima isazi ivu ibikoresho. Ibi bikoresho byombi byakusanyirijwe mubipimo byigihugu, tekinoroji irakuze, kandi haribikorwa byinshi bifatika. Gukoresha ivu ryisazi hejuru ya pavement nubuso bwa asfalt ivanze nubutaka bwa sima. Jiao Hua wo mu bushakashatsi bwakozwe na kaminuza ya Chang'an mu isomo rya shebuja yerekana ko iyo ivu ry’isazi risimbuye ifu y’amabuye yose ivanze na AC-16 ivanze na asifalt, iba ifite ubukana buke bw’ubushyuhe buke ndetse n’ubushyuhe bwo hejuru cyane kuruta kuvangwa n’ifu y’amabuye. , amazi meza yarahinduwe ariko ingaruka ntabwo zigaragara. Xie Jun, Wu Shaopeng, n'abandi bize ubushakashatsi ku ngaruka zo kuvura isazi ivu hamwe n’ibikoresho bifatanya ku kwangirika kw’imvange ya asfalt. Gukomatanya kuzuza hamwe noguhuza hamwe nisazi ivu byitwa compite fly ash modifier. Ibiranga isazi ihinduranya ivu byaranzwe ahanini no gusikana microscopi ya electron na Fourier transform infrared spectroscopy. Nkuwuzuza, ingaruka zacyo kumyunyu ngugu yimvange ya asfalt yasuzumwe nigeragezwa rya modulus itaziguye, ibipimo bihamye, hamwe n’ibizamini by’umunaniro utaziguye. Ibisubizo byerekana ko ivangwa rya asfalt hamwe nisazi ihinduranya ivu ifite imbaraga nyinshi zitaziguye kandi zingana nimbaraga mugihe cyubukonje kandi ifite ububobere buke. Byongeye kandi, ifumbire mvaruganda ihinduranya ivanze rya asfalt yerekanaga uburyo bwiza bwo gukomera, kurwanya ihindagurika rihoraho, nubuzima bwumunaniro nyuma yo kuvura ibyangiritse. Umwanzuro: Guhindura isazi ihinduranya ivu irashobora kunoza neza ububobere buke bwimvange ya asfalt.

Inkombe z'ivu nazo zikoreshwa cyane mubuhanga bwo mumuhanda, cyane cyane mubice byubutaka bworoshye. Irashobora gukoresha byimazeyo uburemere bworoshye bwivu ryisazi kugirango igabanye uburemere bwurwo rugabano hamwe nubundi buryo bwo guhangayikishwa nubutaka bworoshye, bityo bigabanye gutura neza no guteza imbere inkombe. Mu buryo nk'ubwo, kuzuza ivu ryisazi hamwe nubutaka bwuzuye hejuru yikiraro kirashobora kunoza ikibazo cyo gusimbuka ikiraro cyatewe no gutura guterwa no kwikorera uburemere bwubutaka bwuzuye hejuru yikiraro. Liu Tiejun yize ibijyanye nubukanishi bw ivu ryisazi ryakoreshejwe nk'uzuza inkombe maze agera ku myanzuro ikurikira: ubwinshi bwumye bw ivu ryisazi bwerekanaga uburyo bwo kwiyongera mbere hanyuma bikagabanuka hamwe no kwiyongera kwubushuhe, hamwe nubucucike bwinshi bwumye bwamazi yari 19%; Coefficient de coiffe ya ivu yamakara igabanuka cyane hamwe no kwiyongera kwinshi. Iyo ubwinshi bwumye bw ivu ryisazi ruri munsi ya 1.35g / cm3, ubwinshi bwumye nta ngaruka bigira kuri coefficient yacyo; guhuriza hamwe kw'ivu ry'isazi byiyongera hamwe n'amazi Iyo amazi yubushyuhe bwivu yisazi yiyongereye kandi akagabanuka, kandi kugabanuka gutinda mugihe ubuhehere buri munsi ya 26%, bitabaye ibyo bikagabanuka vuba; iyo ubuhehere buri mu ivu ryisazi bwiyongereyeho 1%, inguni yo guterana imbere igabanukaho 0,25 °; Ihuriro ry ivu ryamakara ryiyongera kumurongo hamwe no kwiyongera kurwego rwo kugabanuka, mugihe impande zo guterana imbere zivu zisazi ziyongera cyane hamwe no kwiyongera kurwego rwo kugabanuka; ibivumbikisho by'ivu biguruka Hafi yubushuhe bwiza cyangwa hafi yo guhuza 100%, niko kugabanuka kugabanuka hamwe no guterana imbere imbere hamwe nigihe cyo kunyeganyega, kandi biroroshye kugera kumiterere ihamye kare. icyiciro cyo kunyeganyega. Chen Yunyong na Gao Liang bakoze kandi ibizamini by'icyitegererezo mu nzu ku nkombe z'isazi zishimangirwa. Dukurikije ihame ryo guhuza, abo bagabo bombi bagabanije inkombe nyayo ku kigereranyo cya 1: 8 kandi bakoresha geogridi y’ibice bibiri nkibikoresho byongera imbaraga, kandi bakora ubushakashatsi bwubushakashatsi ku guhangayikishwa n’imivu y’isazi ishimangira inkombe. Ibisubizo byerekana ko gutura ku buryo butaringaniye ku nkombe y’ivu bishobora kugabanuka ku buryo bugaragara hifashishijwe ingufu za geogrid, kandi ubushobozi bwo gutwara inkombe burashobora kunozwa ku buryo bugaragara.
