Imiterere y'ikoreshwa ry'ubushakashatsi ku ivu ry'umukungugu mu by'ubwubatsi bw'imihanda muri iki gihe

Gukoresha ivu ry’umukara mu gice cy’umuhanda ahanini byibanda ku bintu bibiri: ibikoresho bihamye by’umukara (lime n’umukara) n’ibikoresho bihamye by’umukara wa sima. Ibi bikoresho byombi byakusanyijwe mu bipimo ngenderwaho by’igihugu, ikoranabuhanga rirakuze, kandi hari uburyo bwinshi bufatika bwo gukoresha. Gukoresha ivu ry’umukara ku buso bw’umuhanda ahanini ni ubuso buvanze n’ubuso bwa sima. Ubushakashatsi bwa Jiao Hua wo muri Kaminuza ya Chang'an mu nyandiko ye y’icyiciro cya kabiri cy’amashuri makuru bwerekana ko iyo ivu ry’umukara risimbura ifu yose y’amabuye mu mvange ya asphalt ya AC-16, rigira ubushobozi bwo kudacika mu bushyuhe buke kandi rikagira ubushyuhe bwinshi kuruta ivu ry’amabuye. , ubuziranenge bw’amazi bwarushijeho kuba bwiza ariko ingaruka ntizigaragara cyane. Xie Jun, Wu Shaopeng, n’abandi bigaga ingaruka z’ivu ry’umukara n’umukara ku kwangirika k’ubushuhe bw’imvange ya asphalt. Guhuza ivu n’umukara n’umukara byitwa modifier y’umukara. Imiterere ya modifier y’umukara n’umukara yarangwaga ahanini no gupima mikorosikopi ya elegitoroniki na spectroscopy ya Fourier transform infrared. Nk'icyuzuzo, ingaruka zayo ku bushyuhe bw'ibivange bya asphalt zasuzumwe hakoreshejwe ibizamini bya modulus yo gukomera mu buryo butaziguye, static creep, n'ibizamini bya tensile fatigue. Ibisubizo bigaragaza ko uruvange rwa asphalt hamwe na composite fly ash modifier rufite imbaraga nyinshi zo gukomera mu buryo butaziguye n'imbaraga zo gukomera mu gihe cy'ubukonje kandi rufite ubushobozi bwo kwihanganira ubushyuhe bwinshi. Byongeye kandi, uruvange rwa asphalt rwo gukomera mu buryo butaziguye rwagaragaje uburyo bwiza bwo gukomera, kurwanya imihindagurikire ihoraho, no kumara igihe kinini nyuma yo kuvurwa kwangirika k'ubushyuhe. Umwanzuro: Compound fly ash modifier ishobora kunoza neza uburyo uruvange rwa asphalt rushobora kwihanganira ubushyuhe.

Ibice by'ivu ry'umukungugu bikoreshwa cyane mu mihanda, cyane cyane mu bice by'imihanda y'ubutaka bworoshye. Bishobora gukoresha neza uburemere bworoheje bw'ivu ry'umukungugu kugira ngo bigabanye uburemere bw'ivu ry'umukungugu n'inyongera y'umushinga w'ubutaka bworoshye, bityo bigabanye uburyo bwo gutura neza no kunoza uburyo bwo kuguma mu ivu. Mu buryo nk'ubwo, kuzuza ivu ry'umukungugu n'ubutaka bwuzuza byinshi ku mutwe w'ikiraro bishobora kunoza ikibazo cyo gusimbuka kw'umutwe w'ikiraro giterwa no gutuza bitewe n'uburemere bw'ubutaka bwuzuza byinshi ku mutwe w'ikiraro. Liu Tiejun yize ku miterere y'ivu ry'umukungugu rikoreshwa nk'iryuzuza ry'umukungugu maze agera ku mwanzuro ukurikira: ubucucike bw'ivu ryumye bwerekanye ko butangira kwiyongera hanyuma bukagabanuka uko ubushuhe bwiyongera, kandi ubucucike ntarengwa bw'ubushuhe bwumye bwari 19%; Ubucucike bw'ivu ry'amakara bugabanuka cyane uko ubucucike bwumye bwiyongera. Iyo ubucucike bw'ivu ryumye riri munsi ya 1.35g / cm3, ubucucike bwumye nta ngaruka bugira ku bucucike bw'ivu ryumye; Ukwihuza kw'ivu ry'umukungugu kwiyongera hamwe n'amazi. Iyo ubushuhe bw'ivu ry'umukungugu bwiyongera bukagabanuka, kandi bukagabanuka buhoro iyo ubushuhe buri munsi ya 26%, bitabaye ibyo bugabanuka vuba; iyo ubushuhe bw'ivu ry'umukungugu bwiyongeraho 1%, inguni y'ubushuhe bw'imbere igabanukaho hafi 0.25°; Ukwihuza kw'ivu ry'amakara kwiyongera ku murongo uko urugero rw'ubushuhe bwiyongera, mu gihe inguni y'ubushuhe bw'imbere bw'ivu ry'umukungugu yiyongera cyane uko urugero rw'ubushuhe bwiyongera; ubushuhe bw'ivu ry'umukungugu. Iyo ubushuhe bwegereye ubushuhe bwiza cyangwa ubwo hafi ya 100%, niko ukugabanuka k'ubushuhe n'inguni y'ubushuhe bw'imbere bigabanuka uko ibihe by'ubushuhe byiyongera, kandi biroroha kugera ku mimerere ihamye mu ntangiriro z'ubushuhe. Chen Yunyong na Gao Liang nabo bakoze ibizamini byo mu nzu ku bihome by'ivu ry'umukungugu byakomejwe. Dukurikije ihame ryo gusana, aba bagabo bombi bagabanyije agace nyako kari ku gipimo cya 1:8 maze bakoresha imiterere y'ikirere nk'ibikoresho byo gushimangira, kandi bakoze ubushakashatsi ku mvune n'uburemere bw'agace k'ivu ry'umukungugu byakomejwe. Ibisubizo bigaragaza ko uburyo uruziga rw'ivu rushobora kugabanuka cyane hakoreshejwe ingufu za geogrid, kandi ubushobozi bwo gutwara uruziga bushobora kunozwa cyane.
