Mphamvu ya Kusakaniza Kwamadzi ndi Madzi ndi Kasamalidwe ka Malo Omanga Pakumanga Konkrete ya Foam ya Cast-in-Place

1.The impact of water-liquid mixing ratio on project quality

Pakadali pano, there are many manufacturers that produce foaming agents. They design the water-liquid mixing ratio of the foaming agent in a fixed way, making it impossible to adjust the water-liquid mixing ratio, which brings limitations to users in choosing the types of foaming agents. Because different projects have different functional requirements, the type of foaming agent should be selected according to the actual situation of the project. Different foaming agents have different water-liquid mixing ratios. A foaming machine without a water-liquid mixing ratio adjustment mechanism will bring difficulties to the construction of foamed concrete. Pali mitundu yambiri ya zinthu zotulutsa thovu, zomwe zingathe kugawidwa m'magulu atatu: mtundu wa mbewu, mtundu wa nyama ndi mtundu wapawiri. Palinso zida zapadera zotulutsa thovu. Chiŵerengero chosakanikirana cha madzi ndi madzi chimakhala ndi magiredi osiyanasiyana monga 1:20, 1:30, 1:40…1:100, ndi omwe amagwiritsidwa ntchito kwambiri 1:30~1:50. Chifukwa ndende ya thovu wothandizira njira mwachindunji zimakhudza bata ndi magazi a thovu, zimakhudza khalidwe la konkire thovu. Pankhani yotulutsa thovu yofananira, ang'onoang'ono ndende, choyipa kwambiri kukhazikika kwa thupi la thovu, ndi kufulumira kwa magazi a thovu. Komabe, ngati ndende ndi yaikulu kwambiri, kutulutsa thovu ndi kocheperako ndipo chiŵerengero cha thovu ndi chochepa, zomwe zidzawononga. Choncho, mitundu yosiyanasiyana yotulutsa thovu imakhala ndi mitundu yosiyanasiyana yosakanikirana yamadzi ndi madzi. Izi zimafuna kuti wopanga chopangira thovu akonze njira yosinthira madzi ndi madzi osakanikirana amtundu wa thovu., yomwe ndi yabwino kwa ogwiritsa ntchito kusintha ndikugwiritsa ntchito kupanga konkriti yapamwamba kwambiri ya Foamed. Pakadali pano, ambiri opanga thovu opangidwa ndi opanga ali ndi njira yosinthira kuchuluka kwa thovu, koma palibe njira yosinthira kusakaniza kwamadzi ndi madzi amadzimadzi amtundu wa thovu. Izi zidzakhudza kupanga khalidwe la thovu konkire kumlingo wakutiwakuti.

2. Mphamvu ndi kuwongolera kwa kasamalidwe ka malo omanga pamtundu wazinthu

Mosasamala kanthu kuti ndi denga loponyera padenga kapena denga la khoma, chithandizo chonyowetsa cha mawonekedwe pakati pa konkriti yokhala ndi thovu ndi wosanjikiza wamapangidwe ndizofunikira kwambiri ndipo zimakhudza mwachindunji mtundu wazinthu..

Asanamangidwe, pamwamba pa structural wosanjikiza ayenera kutsukidwa kuchotsa fumbi akuyandama. Zigawo zowonongeka ndi zotayirira za kapangidwe kakale ziyenera kuchotsedwa. Ndiye madzi ayenera wothira bwino, ndipo nthawi ya madzi iyenera kuzindikirika. Isakhale yowuma kwambiri kapena yonyowa kwambiri, makamaka padenga. Omanga ambiri sachita kalikonse pankhaniyi. Pankhani ya chilimwe chouma kwambiri, Direct kuponya-mu-malo, kapena kusungirako madzi mopitirira muyeso mvula itatha popanda kuthirira madzi, kumabweretsa mavuto ambiri abwino. Chifukwa chosanjikiza chomangika ndi chouma kwambiri, pamwamba pa structural wosanjikiza mwamsanga kuyamwa madzi kuchokera thovu simenti slurry, kuchititsa kukhudzana wosanjikiza wa thovu simenti kutaya madzi ndi defoam mofulumira, kusandulika kukhala ufa wowuma wowuma wa simenti, zomwe zimakhudza hydration ya simenti Zomwe zimachititsa kuti pakhale mgwirizano wofooka komanso kupanga ng'oma yopanda kanthu. Ngati pali madzi ochulukirapo pamwamba pa chigawo chokhazikika, izo mwamsanga kuchepetsa thovu konkire kukhudzana wosanjikiza. Pambuyo chithovu ndi kuchepetsedwa ndi madzi, ichita thovu, kuswa, ndi simenti yolimba. Zidzapangitsanso kuti gawo lolumikizana lipange makulidwe ena a matope a simenti, zomwe zidzasintha chiŵerengero cha madzi ndi zinthu zosakaniza za konkire ya thovu, kuchititsa kugumuka kwa nthaka ndi ming'alu ya pamwamba, zomwe zidzakhudza ubwino wa mankhwala Zinayambitsanso zinyalala zopangira. Choncho, ulalo uliwonse pakuwongolera malo omanga ndiwofunikira kwambiri ndipo udzakhudza mwachindunji mtundu wazinthuzo. Choncho, ndikofunikira kwambiri kukweza chidziwitso cha ogwira ntchito yomanga ndi oyang'anira.

Cie-China.org ndiye wotsogola wotsogola wa konkriti wa thovu yemwe amapereka thovu la konkriti, superplasticizer,thovu konkire mphamvu zowonjezera kwa wopepuka konkire, Zolemba za CLC. Ngati mukuyang'ana wotulutsa thovu, chonde khalani omasuka Lumikizanani nafe.
