1. Imiterere y'umutungo w'icyuma gikoreshwa muri iki gihe:

Ifu y'icyuma imaze igihe kinini ishyirwa mu bipimo ngenderwaho by'igihugu nk'uruvange rwa sima. Ibizamini byinshi byo kugereranya byagaragaje ko: Iyo ubuso bwihariye bw'ifu y'icyuma irenga 420m2/kg, imikorere yayo isa n'iya slag yo mu itanura. Kuvanga ifu y'icyuma ivanze n'ifu y'icyuma ntibishobora kongera gusa igipimo cy'ifu y'icyuma ivanze mu ifu ivanze, ahubwo binakongera ingano y'ifu ivanze n'isima hashingiwe ku gukora neza kwa sima, kugira ngo birusheho kugabanya ikiguzi cyo gutegura sima. Bishobora kugabanya guhindagurika kw'icyuma gifunga no kunoza ubudahangarwa bw'icyuma gifunga. Ibi bigaragaza ko ibicuruzwa by'icyuma bivanze bifite amahirwe meza ku isoko. Kuri ubu, ingano y'icyuma iragabanuka bitewe no kuba hari CaO na MgO bidafite ubuziranenge. Ingano nyinshi ya oxide y'icyuma yongera ingorane zo gusya, ikoreshwa ry'ingufu nyinshi za toni, ndetse n'ingorane zo gutunganya ifu y'icyuma ivanze. Kubwibyo, ingano y'isoko ry'ifu y'icyuma ni nto, ibyo bigatuma ifu y'icyuma iba isoko ririmo iterambere.

2. Kuvanga sima bitanga umwanya wo gukoresha icyuma gisya ibintu bitameze neza cyane:

Kuvanga sima hakoreshejwe beto ni impinduka ikomeye mu mikorere y'imishinga y'ubwubatsi, kandi igipimo cy'ikoreshwa rya sima ivanze neza kigaragaza urwego rw'umusaruro w'inganda za beto mu gihugu. Imyitozo igaragaza ko ikoreshwa rya sima ivanze neza rishobora kongera umusaruro w'abakozi inshuro zirenze ebyiri, rigatuma sima igabanukaho 10% kugeza 15%, rigagabanya ikiguzi cy'umushinga kigera kuri 5%, kandi rigatuma umushinga uba mwiza, rigakiza ubutaka bw'ubwubatsi, rigagabanya ivumbi, kugira ngo hubakwe ibidukikije. Iterambere rya sima y'ubucuruzi riteza imbere iterambere ry'umusaruro w'ifu ya sima kandi rikongera isoko ry'ubukene bw'ifu ya sima. Uruganda rwo kuvanga sima mu Bushinwa rwashinzwe mu myaka ya 1980, rwatangiriye i Shanghai, Jiangsu n'ahandi, bitewe n'ubwiyongere bw'ubunini bw'ubwubatsi, cyane cyane bitewe n'iterambere ryihuse ry'ubwubatsi bw'imijyi yo ku nkombe z'amajyepfo y'uburasirazuba, hamwe na politiki n'ingamba zishyigikiwe n'inzego z'ubwubatsi, ku buryo sima ivanze neza mu mujyi yiyongeraho 15% buri mwaka. Kubera ko igiciro cya slag n'icyuma kiri hasi ugereranyije n'icya sima, sima ivanze na slag n'icyuma ihendutse kandi ikwiriye gukoreshwa muri sima ivanze cyane. Sima ikorwa mu kuvanga slag n'icyuma na sima, amabuye n'umucanga w'umuhondo ifite ibyiza byo gukomera cyane, ubushyuhe buke, kudashira neza no gukomera cyane hamwe n'ibyuma. Ikwiriye cyane cyane inyubako ndende, INDAMU, ibibuga by'indege, ishingiro rinini ry'ubujyakuzimu n'imishinga yo munsi y'amazi. Kuri ubu, sima ikomeye cyane itegurwa ahanini mu kuvanga ivu rya silica n'ibikoresho bigabanya amazi neza, ariko kubura ibikoresho fatizo bya silica n'ibikoresho bigabanya amazi neza birahenze, bigatuma sima ihenda cyane. Bitewe n'ibisabwa byinshi ku miterere ya sima mu mishinga minini yihariye, gukenera cyane sima y'ubucuruzi byatumye isoko rinini rikoreshwa cyane mu gukoresha ivu rya slag n'icyuma. Abantu basobanukiwe imiterere ya slag n'icyuma, ibikoresho bishya by'ubwubatsi, nabyo biriyongera. Hamwe no guteza imbere no gukoresha beto y’ubucuruzi mu gihugu no gushyira mu bikorwa amahame ngenderwaho y’igihugu ajyanye n’ibikomoka ku ifu ya slag n’icyuma, hamwe no gushyira mu bikorwa politiki nko kubuza burundu kuvanga beto ahantu h’ubwubatsi mu mijyi, isoko ry’ifu ya slag n’icyuma rizarushaho kuba rinini, kandi ikoreshwa ryayo rizakurura abantu benshi.

3. Uburyo bwo gutegura n'ibikoresho byo gusya icyuma gikozwe mu ifu ntoya byamamaye kandi bikoreshwa

Muri iki gihe, ikoranabuhanga ryo gusya rihagaze rikoreshwa mu gusya ifu ntoya ya slag y'icyuma no gukora ibintu bisimbura clinker ya sima ifite ingufu nyinshi, ikaba ari imwe mu ikoranabuhanga rigezweho mu nganda. Mu bihe byashize, ubusanzwe slag, slag y'icyuma na clinker ya sima, gypsum, nibindi byahuriraga hamwe, hakurikijwe ingano runaka y'isya mu gukora sima. Bitewe n'uko slag n'icyuma bidakora neza, isya ntishobora gusya neza iyo ivanze na clinker ya sima, imikorere yayo ntishobora gutezwa imbere byuzuye, kandi ingano n'ikoreshwa rya slag n'icyuma bigengwa ku rugero runaka. Mu gutegura ifu nziza cyane iva muri slag y'icyuma gusa, ibigo by'ibyuma bya Jiangsu n'ibyuma biri ku isonga. Ibigo byinshi by'ibyuma bihagarariwe na Changzhou Zhongtian Iron and Steel byubatse imirongo yihariye yo gukora slag y'icyuma. Nk'uruganda rukora icyuma gipima ifu ntoya, HCM Machinery itanga ubufasha bwa tekiniki mu nzira yo gusya ifu nziza cyane no mu gukora ibikoresho by'ingenzi by'imashini. Ibiranga tekiniki byayo ahanini ni ibi bikurikira: guhitamo ifu y'icyuma gisya ikoresheje icyuma gisya, gifite ikoranabuhanga rigezweho, umusaruro wizewe, imiterere y'umusaruro mwinshi w'abakozi, hamwe n'icyuma gisya gipima toni imwe y'ubuso bwihariye bwa 400m2/kg ~ 500m2/kg, ifu y'icyuma gisya, kurusha ikoreshwa rya gakondo ry'icyuma gisya gifite uburemere bumwe bwo kuzigama amashanyarazi 30% ~ 50%; Ifu nziza y'icyuma gisya ivanze na sima ivangwa muri sima, ibi bikagabanya ingano ya sima bityo bikagabanya ingufu zikoreshwa mu gukora sima. Igisya, uburyo bwo gusya icyuma gisya, bushobora guhindura neza ubuziranenge bw'ibicuruzwa hakurikijwe ibyo isoko rikeneye. Iyo hongewemo icyuma gisya ifu n'icyuma muri sima, ubushyuhe n'ibice byangiza bya sima bishobora kugabanuka, bigatuma habaho imiterere myiza yo kunoza imikorere ya sima hamwe n'ingufu nke. Igisya cy'icyuma gisya ifu ikoresheje icyuma gisya, kandi ibikoresho bigasya ahantu hatose ku bushyuhe bwinshi (100℃ ~ 300℃). Inyinshi muri okiside ya kalisiyumu yigenga na okiside ya manyeziyumu yigenga mu ifu ya micro-slag y'icyuma zishyirwamo kalisiyumu hidroksidi na manyeziyumu hidroksidi. Byongeye kandi, bitewe no gushyiramo slag n'icyuma muri beto, uburyo alkali aggregate ishobora kugabanuka neza, uduce duto twa beto dushobora kwirindwa, kandi igihe cy'inyubako gishobora kongerwa. Kubwibyo, beto ivanze n'ifu ya slag yishimirwa n'inganda z'ubwubatsi kubera imiterere yayo yihariye. Slag yo gusya icyuma yonyine ishobora gukoreshwa nk'umusaruro wo gukora beto no kuvanga hakurikijwe ibyo isoko rikeneye, kandi ishobora no guhindurwa hakurikijwe ko bikenewe guhindura ubunini n'ingano yo kuvanga bigomba gushyirwa muri sima yo kugurisha.
