Calcium wopanga imatha kukhala yokhazikika ngati matalala ku konkriti. Umu ndi momwe zimagwirira ntchito:

Kukhazikitsa njira zopangira:

1. Njira ya hydration: Pamene calcium Facrete imawonjezeredwa ku zosankhidwa ndime, zimasungunuka m'madzi ndikutulutsa ma calcium aon (ca ^ 2 +) ndikupanga ma iyoni (hcoo ^ -).
2. Kulimbikitsa mapangidwe a CRS: katswiri wa calcium nes (ca ... 2 +) Kutulutsidwa ku calcium kupanga ndi ma silmium mu simenti syrate (CSH) Gelder (CSH) Gel. Kholu la Chuma iyi ndi khola yoyamba ku konkriti, yomwe imayambitsa mphamvu ndi kukhazikika.
3. Kutalika mwachangu: mapangidwe othamanga a CSH Geli amabweretsa nthawi yokhazikika ya nthawi yosinthira konkriti. Izi zimathandiza kuti afulumalizire mwachangu komanso kuchotsedwa kwakale kwa mawonekedwe, kufulumira njira yonse yomanga.

Ubwino wogwiritsa ntchito calcium kupanga ngati maonjetsi:

1. Mphamvu Yoyambirira: Mphamvu yoyambirira ya konkriti imalimbikitsidwa chifukwa cha kuchuluka kwa ma hydrate njira yothandizira calcium polojekiti. Izi zitha kukhala zopindulitsa kwambiri nyengo yozizira pomwe nthawi yokhazikika imawonedwa.
2. Kuchepetsa Ntchito Yomanga: Pakuthamangira nthawi yokhazikika, katswiri wa calcium kumathandizira kuchepetsa nthawi yomanga ndikulola kumaliza ntchito polojekiti mwachangu.
3. Kugwiritsa Ntchito Mphamvu: Katswiri wa calcium amathanso kusintha kugwiritsidwa ntchito kwa konkriti, kumapangitsa kuti zikhale zosavuta kuzigwira ndi malo, makamaka m'malo omwe makonzedwe amafunikira.

Kugwiritsa ku konkriti:

• Calcium Facrete imawonjezedwa ku zosankha za konkriti pamlingo wochokera ku 0,1% mpaka 2% polemera simenti, kutengera nthawi yokonzekera ndi zofunikira.
• Nthawi zambiri zimagwiritsidwa ntchito ku Prescast konkriti konkriti, mapulogalamu owombera mfuti, komanso ntchito zomanga pomwe malo okhazikika ndikofunikira.

Kuganizira

• Pomwe katswiri wa calcium amatha kuthandizira kukhazikitsa nthawi ya konkriti, ndikofunikira kuti muganizire kuchuluka kwa mankhwala ndi kulingana ndi ma admintixtores ena kuti mupewe mavuto a konkriti.
• Njira zowongolera zoyenera ziyenera kukhazikitsidwa kuti zitsimikizidwe kuti zowonjezera zimakhala ndi mphamvu zomwe mukufuna, kukhazikika, komanso magwiridwe antchito.

Calcium wopanga imagwira ntchito yokonza zowonjezera ku Concete, kulimbikitsa mwachangu komanso kulimbikitsa. Kugwiritsa ntchito kwake kumatha kuthandiza kukonzekera zomangamanga ndikusintha, makamaka nyengo yozizira kapena ntchito. Komabe, mlingo woyenera komanso wogwirizana ndi wogwirizana ndizofunikira kuti akwaniritse zomwe mukufuna kupanga pomwe kugwiritsa ntchito calcium kumapangitsa kuti calcium ikhale ngati yowonjezera.
