Ivyivanga bigabanya amazi bikora neza cane: Bituma beton ikora neza mu kwubaka ivyatsi bitotahaye
Ibisabwa bikomeye
Ivyuma bigabanya amazi bikora neza cane (nk’ivyuma bikoreshwa mu gutera amazi) ni vyo bigereranya ubwoko buteye imbere kuruta ubundi bwose bw’ivyuma bigabanya amazi biri kw’isoko. Bikora mu guhingura igice c’ugushwiragira ku ruhande rw’ibice vya simenti, bikabuza ko ibice vya simenti biteranira hamwe, gutyo bikaba bituma beton ishobora gutemba neza kandi igakora neza. Ivyo bitera gushwiragira ntibigabanya gusa amazi akoreshwa, ariko kandi biratuma beton igira uburemere n’ubukomezi. Ugereranije n’ibikoresho vya kera bigabanya amazi, ibikoresho bikora neza cane bitanga ibipimo vyinshi vyo kugabanya amazi (mu bisanzwe 25%-40%) n’ivyo bisabwa bike (mu bisanzwe 0,1%-0,3% vy’umubare wose w’ibikoresho vya simenti), bikaba bifise ingaruka ntoyi ku bidukikije.
Mu migambi y’ubwubatsi, gukoresha ibintu bigabanya amazi birashobora kwongereza cane inkomezi z’ugukomera kwa beton no guhangana n’amazi, bigatuma inyubakwa zimara igihe kirekire. Nk’akarorero, mu kwubaka inyubakwa ndende n’ibiraro bininibinini, ibintu bivanze bigabanya amazi bikora neza cane biratuma beton ishobora gutemba neza iyo isaba inkomezi nyinshi, ivyo bikaba bituma ibikorwa vy’ubwubatsi vyoroha. Vyongeye, ibintu bigabanya amazi birashobora kugabanya amaraso n’ugutandukanya muri beton, bigatuma imera neza kandi ikaba ihuye.
Mu bijanye n’ubwubatsi bw’ivyatsi bitotahaye, ibiranga ibidukikije vy’ibintu bivanze bigabanya amazi birahambaye cane. Gukoresha ibintu bigabanya amazi bifise ubushobozi bwinshi birashobora kugabanya ikoreshwa rya simenti, gutyo bikagabanya ivyuka bihumanya ikirere. Vyongeye, ivyo bivanze birashobora gutuma beton igumaho, bikagabanya amahera yo kuyibungabunga be n’ivyo inyubakwa zikoresha. Ivyuma vyinshi bigabanya amazi bifise ubushobozi bwinshi na vyo nyene vyaronse ivyemezo mpuzamakungu vyerekeye ibidukikije, bikaba bihuye n’intumbero z’iterambere riramvye z’ubwubatsi bushingiye ku bidukikije.
Kubera ko ubuhinga bwo kwubaka buguma butera imbere, n’ugukoresha ibintu bigabanya amazi na vyo nyene biragenda biragwira. Nk’akarorero, muri beton ikora cane (HPC) no muri beton yikomeza (SCC), ibintu bigabanya amazi ni vyo bifasha cane beton kwiringaniza iyo iri mu bihe vy’uburemere bwinshi n’ubukomezi bwinshi. Ikindi, ibintu bigabanya amazi birashobora gukoreshwa hamwe n’ibindi bikoresho (nk’ibintu bigabanya amazi n’ibintu bigabanya umuyaga) kugira ngo birushirize gutuma beton ikora neza.

Mu ncamake
Ivyongeweko bigabanya amazi ni vyongeyeko bihambaye mu buhinga bwa none bwo gukora beton. Ntizituma gusa beton ikora neza, ariko kandi zifasha mu kwubaka ivyatsi bitotahaye no mu guteza imbere iterambere riramvye. Kubera ko ubuhinga buzobandanya gutera imbere, ivyizigiro vyo gukoresha ibintu bigabanya amazi bizoba mbere vyinshi.
