Imyanda ikomeye yo mu Bushinwa ni imiyoboro y’amazi, ivu ry’ibimera, gangue y’amakara, ifu ishongesha, ifu ikoreshwa mu makara n’ifuru ya gypsum. Gutegura ibikoresho by’ubwubatsi bivuye mu myanda ikomeye byakuruye ibitekerezo byinshi. Abashakashatsi bongereye uburyo bwo gukoresha imyanda ikomeye mu nganda z’ibikoresho by’ubwubatsi binyuze mu kunoza no gukora ubushakashatsi no guteza imbere ibikoresho n’ikoranabuhanga. Muri icyo gihe, ibihugu bitandukanye byasohoye amategeko n’amabwiriza ashyigikira ibikorwa byo gushishikariza ibigo gukoresha imyanda ikomeye, bityo bikongera ingaruka z’imyanda ikomeye yo mu nganda ku bidukikije ku rugero runaka. Nk’uruganda rukora uruganda rusya ibyuma,uruganda rukora imigozi ihagaze mu byuma yakoreshejwe cyane mu mushinga wo gukoresha ibikoresho by'ubwubatsi mu gusya umucanga mu byuma. HCMilling (Guilin Hongcheng) izashyira ahagaragara ikoranabuhanga ryo gutegura ibikoresho by'ubwubatsi mu byuma bivanze n'ibyuma.

1. Imashini ikora sima ifite calcium

Ubushyuhe bw'icyuma bukungahaye ku bintu by'icyuma, bishobora gusimbura ifu y'icyuma nk'ibikoresho fatizo byo gukora sima clinker. Gutwika sima clinker hamwe n'amabuye y'agaciro, umucanga wa quartz n'ibyuma nk'ibikoresho fatizo bishobora kugabanya ubushyuhe bwa calcination n'igiciro cya sima, ariko ingano yo kuvanga ni ntoya, kandi ingano irenze urugero yo kuvanga izagabanya cyane imbaraga za sima. Kuri ubu, ingano y'ibyuma bikoreshwa mu gukaraba sima clinker ni hafi 15%. Ni ngombwa guteza imbere ibikoresho bishya n'ikoranabuhanga rishya kugira ngo twongere ingano y'ibyuma bikozwe mu cyuma kandi tumenye neza ko umusaruro wa sima ari mwiza.

2. Ihuriro rya beto

Ubukana bwinshi bw'imitako y'icyuma ahanini buturuka ku gice cy'imbere cya quartz, gifite ingano hafi y'umusenyi wo mu ruzi n'umucanga wakozwe, kandi gishobora kuvangwa muri beto nk'umusenyi. Beto ifite imbaraga za 28d za 40MPa ishobora gutegurwa hakoreshejwe imitako y'icyuma ifite ingano y'ibice iri munsi ya mm 1 kugira ngo isimbuze umusenyi wo mu ruzi nk'umusenyi muto. Hashingiwe ku kunoza uburyo bwo gushyira mu byiciro, gukoresha imitako y'icyuma n'umusenyi wakozwe n'imashini nk'umusenyi ntabwo bishobora guhaza gusa ibisabwa na beto ku bikoresho, ahubwo binatuma isura y'icyuma n'umusenyi wo mu ruzi ikomera, ibyo bikaba byoroshye kugenzura ubuziranenge bwa beto. Ku bijyanye n'uburyo bwo kongera ubwiza bw'icyuma, kugira ngo hongerwe igipimo cyo kugarura icyuma, imitako y'icyuma irimo irushaho kuba myiza, ibyo bikaba bigoye kuzuza ubuziranenge bw'imitako ikomeye no kuyishyira kuri beto isanzwe.

3. Imvange y'amabuye y'agaciro ya beto

Uruvange rw'amabuye y'agaciro rugizwe ahanini n'ibikoresho bya siliceous, calcareous na aluminiyumu bidafite imvange, bigira uruhare runini mu kunoza ubucucike, ububobere n'ubudahangarwa bwa sima. Bishobora kugabanya ikoreshwa rya sima no kugabanya ubushyuhe bw'amazi icyarimwe. Kubwibyo, ni ngombwa gushaka uruvange rushya rw'amabuye y'agaciro kugira ngo inganda za sima zikomeze gutera imbere mu buryo burambye. Icyiciro cy'ingenzi cy'amabuye y'agaciro mu byuma bicukurwamo ibyuma akenshi ni quartz, ifite imikorere mike ya pozzolanic mu buryo karemano. Uburyo bwo kunoza "imikorere ya pozzolanic" y'ibyuma bicukurwamo ibyuma bwabaye ingingo nyamukuru y'abashakashatsi ba none. Nk'uburyo bumwe bukoreshwa cyane mu gukoresha ibyuma bicukurwamo ibyuma, gusya hakoreshejwe ikoranabuhanga bishobora kugabanya ingufu zo gukoresha ibyuma bicukurwamo ibyuma kandi bigatera inenge nyinshi no guhinduka kwa plastiki. Ubushakashatsi bwerekana ko gusya hakoreshejwe ikoranabuhanga bishobora gutera imbaraga imikorere ya pozzolanic y'ibice bisanzwe by'amabuye y'agaciro mu byuma bicukurwamo ibyuma. Uko ingano y'utunyangingo tw'amabuye y'agaciro acukurwamo ikoranabuhanga igabanuka, quartz ishobora gukorana na Ca (OH) 2 muri sima kugira ngo ikore gel ya silicate ya calcium na crystal ya ettringite n'ibindi bicuruzwa byo gukoresha amazi. Ubushakashatsi bwerekana ko iyo imashini isya iminota irenga 40, inguni ikarishye y'imisatsi y'icyuma iragabanuka cyane, uduce duto twinshi tugaragara, kandi uburinganire bugenda burushaho kwiyongera. Muri sisitemu ya anhydrite ikoresha calcium oxide, imisatsi y'icyuma ya siliceous ikoreshwa mu imashini ishobora kuvangwa na 30% kugira ngo hategurwe sima ya 32.5. Mu gihe cy'ikigereranyo gito cy'amazi, ifu y'icyuma ishobora gutuma amazi ya sima ivanze atangira, bigatuma imiterere y'imyobo ya sima iba nto, kandi ikongera imbaraga za mbere. Kwiyongera k'ubuso bw'imisatsi y'icyuma nta ngaruka igaragara igira mu kunoza ingano y'ibikorwa byayo; Impinduka mu bushyuhe bwo gukaraba ishobora kongera cyane ingano y'ibikorwa mu ntangiriro (7d), ariko bigira ingaruka nke ku ngano y'ibikorwa mu mpera (28d). Kuri sisitemu ya slag ikoreshwa mu imashini, ingano y'ibikorwa ishobora kunozwa binyuze mu kunoza uburyo bwo gukaraba, bityo bikanoza kuramba kwa sima. Gukoresha neza igikoresho gigabanya amazi bishobora kongera ingano y'imisatsi y'icyuma muri sima isanzwe kuva kuri 30% kugeza kuri 40%. Gusya imirasire y'icyuma bishobora kunoza imikorere yo gusya binyuze mu ngaruka zabyo, bityo bigatera imbaraga imikorere y'imirasire y'icyuma. Mu kunoza ikigereranyo cy'imirasire y'icyuma, slag, clinker na gypsum composite sima, beto ifite imikorere myiza cyane hamwe n'imikorere ijyanye n'ibipimo ngenderwaho by'igihugu ishobora gutegurwa.
