Iyo ubushuhe buri hasi, igitigiri c’amazi kigabanuka, ivyo bikaba bigira ico bikoze ku bushobozi bwo kwubaka. Iyo ubushuhe bushitse munsi y’ubukonje, amazi arahinduka urubura, akagwira mu bwinshi, kandi arashobora gutuma habaho utunenge nk’ugutoboka n’ugusenyuka. Amazi amaze guhinduka umwuka, utuzu two mu mutima turagwira, ivyo bikaba bigabanya cane inkomezi z’ico gipfukisho.

Inkomezi z’ivu ahanini zivana n’ingene simenti n’amazi bikora be n’igihe bimara. Iyo wubatse munsi ya 0°C, amazi arakonja, kandi naho ugutera amazi ari igikorwa c’ubushuhe buva hanze (kigatanga ubushuhe bumwe bumwe bw’amazi), ubushobozi bw’ugutera amazi buracagabanuka. Iyo ubushuhe bushitse hejuru ya 0°C, iyo barafu iranyonga, maze amazi agasubira gutera—ariko iyo nzira iragabanya ata kabuza inkomezi za simenti.

 

Ushaka ikintu co kwongerako gifise ubushobozi bwinshi co kwongereza ubushobozi bw’ibifungurwa n’inkomezi za beton? Ivyo dukoresha mu gukora calcium (formate de calcium) bitanga agaciro k’inganda zibiri – dushire ubutumwa kugira ngo dufunge mu citegererezo cawe!
