Abstract:
Inganda zubwubatsi zigira uruhare runini muguhindura isi ya none, murizo sima ariryo nyubako shingiro. Mu myaka myinshi, abashakashatsi na ba injeniyeri bakomeje gushakisha uburyo bwo kuzamura ireme n'imikorere ya sima. Umwe usezeranya aho uhurizamo usibye kongeramo inyongera, muri calcium ikora yabaye umukinnyi uzwi.
Kumenyekanisha:
Ingwate ni ikintu gikomeye cyo kubaka kandi gisaba iterambere rihoraho ryo guhangana ninganda zikenewe. Kwiyongera kw'inyongera byagaragaye ko ari ingamba zifatika zo kuzamura ibintu bitandukanye byo kwihitiramo. Calcium ikora, ikigo cyakozwe na reaction ya calcium oxide na acide ya calcium, yakunze kwitondera ubushobozi bwo kunoza imitungo ya sima. Iyi ngingo igamije guhirika inzira calcium ikora neza igira ingaruka nziza sima n'imikorere.
Calcium ikora imiti yimiti:
Mbere yo kwirukana ingaruka za calcium zikora kuri sima, ni ngombwa gusobanukirwa na chimie yibiriho. Calcium ikora ni ifu yera ya kirisiti hamwe na chimique ca (hcoo) 2. Ni ugushonga amazi kandi ifite imitungo ya hygroscopique. Ihuriro ryihariye rya calcium kandi rikora ion ritanga imiterere yihariye, bigatuma bikwiranye na porogaramu zitandukanye, harimo no kuzamura sima.
Uburyo:
IHINDA RY'IKORESHWA RITANZWE MU RUBANZA RUGENDE RITrekana uburyo bwinshi bugira uruhare mu kunoza imikorere. Uburyo bumwe bukuru burimo style yihuta. Calcium ikora ibikorwa nkumusemburo, guteza imbere imiterere ya hydrate nka calcium ya silicate ya syal (csh) na 1Tite. Uku kwihuta kwimyanda byihuse kandi kongera iterambere ryimbaraga.
Byongeye kandi, calcium ikora ibikorwa nkikibanza cyakabwo kwimvura ya hydrate, igira ingaruka kumishinga ya matrix. Iri jambo riva mu gitsina no kugabura kwa Гиzo umwambaro, dufasha kunoza kuramba no kugabanya umutekano.
Byongeye kandi, gushiraho calcium yitabira ibibazo bya pozamonic, aho bitwaje hydroxide ya calcium kugirango ikore csh gel. Iyi myitwarire idatanga umusanzu mugutezimbere imbaraga gusa ahubwo igabanya ibyago byo gutinda gushiraho (def), ibintu bishobora guhungabanya kurambagiza igihe kirekire.
Gutezimbere Imico ya sima:
Iterambere ryambere:
Ubushobozi bwa calcium bukora kwihutisha imirasire ya sima isobanura iterambere ryinshi mugutezimbere imbaraga. Ibi nibyingenzi mu mishinga yo kubaka aho imbaraga zigomba kunguka vuba. Igenamiterere ryihuse ryamamajwe na Calcium ikora irashobora kuvamo gukuraho byihuse no gutera imbere.
Iterambere ryiyongereye:
Calcium yongeyeho guhindura imishinga mikoro ya sima, bikaviramo ibintu biramba. Ubwiyongere bwayongereye hamwe no gukwirakwiza imyenda imwe bitanga umusanzu wo kongera kurwanya igitero c'imiti, guhagarika ubukonje, no kwambara. Kubwibyo, imiterere ya sima yavuwe na calcium yerekana ubuzima burebure.
Gabanya umutekano:
Kimwe mu bintu by'ingenzi bigira ingaruka ku kuramba kwa beto ni uburemere. Gukora calcium bigabanya ubukuru bushingiye kubikorwa bya pore matrix. Imiterere ya matrix yuzuyemo hamwe nimyumvire ya nziza igabanya inshinge y'amazi n'ibirimo, bityo bikamura imyigaragambyo ya beto yo kwangirika.
Kunanirwa kwa alkali silica reaction (ASR):
Ubushakashatsi bwabonye ko calcium ikora calcium ishobora kugabanya ibyago bya alkali-silika reaction, inzira mbi ishobora gutera gel kubyimba gel no gucika muri beto. Mu kwibasira imiterere ya pore hamwe nibigize imiti yo guhagarika sima, gushiraho calcium ifasha kugabanya ubushobozi bwibyangiritse.
Gutezimbere imikorere:
Imashini inoze:
Ingaruka za Calcium zikora kuri sima hydration zigira ingaruka nziza kukazizwa ka beto nshya. Igihe cyihuse cyashyizweho kandi cyanze hydration kinetics ubufasha kunoza ibiranga ibiranga, koroshya no guhuza beto. Ibi ni byiza cyane cyane aho gushyira mu gaciro ari ngombwa.
Kugenzura Ubushyuhe:
Gukoresha Calcium byashizweho muri cemedi bifasha kugabanya ingaruka zubushyuhe bukabije mugihe cyo gukira. Igenamiterere ryihuta Ibihe bya Calcium birashobora kwihutisha iterambere ryimbaraga no kugabanya intege nke za beto kubibazo bijyanye nubushyuhe nkimiterere yubushyuhe.
Ibitekerezo birambye:
Gukora calcium ifite imitungo yujuje ibitego birambye byinganda zubwubatsi. Poactivite yacyo yo mu buryo bworohereza imikoreshereze y'ibikoresho by'imyanda, n'ingaruka zacyo ku buramba no kuramba bigira uruhare mu kugabanya ibidukikije bifitanye isano no gusimbuza no gusana inzego zishaje.
INGORANE n'ibitekerezo:
Nubwo inyungu zo gushira calcium zikora muri sima zirasobanutse, imbogamizi n'imbogamizi zigomba gusuzumwa. Ibi birashobora kubamo igiciro cyiyongereye, uburyo bushobora kuba hamwe nibindi bisekuru, kandi hakenewe kugenzura umutekano witonda kugirango wirinde ingaruka mbi. Byongeye kandi, imikorere yigihe kirekire hamwe nimbwa ya calcium yafashwe-ukurikije ibintu byihariye ibidukikije byemeza ubundi bushakashatsi nubushakashatsi bwamasomo.
Mu gusoza:
Gushyira Calcium byakora muri sima nuburyo bwo kwiyemeza kuzamura ubuziranenge n'imikorere yibi bikoresho byubwubatsi. Binyuze mu mibereho yacyo myinshi y'ibikorwa, calcium ikora ingendo, biteza imbere ibikorwa kandi bigira uruhare mu mitungo yifuzwa, harimo n'iterambere ry'imbaraga, bishyize imbere iterambere kandi bigabanuka. Nkuko inganda zubwubatsi zikomeje guhinduka, uruhare rwinyongera nka calcium igira uburyo bwogutezimbere bwa sima bushobora kuba ingenzi. Ubushakashatsi hamwe nibisabwa bifatika bizashimangira kandi gukoresha neza Calcium ikora muri sima, guha inzira inyubako zihanganye kandi zirambye.
