Kodi chisanu kukana konkire

Frost kulimbikira zomangira chimasonyeza mmene chitsanzo makamaka akhoza kukhalabe katundu pambuyo m'zinthu angapo motsatizana yozizira koopsa ndi thawing. Pankhani ya simenti, Woyambirira chifukwa kwe nthaŵi awa amakhala madzi mu boma olimba, amene umalimbikitsa ndithu pa makoma a microcracks ndi pores zakuthupi.

Nayenso lalikulu konkire madzi kuuma si kukuza momasuka, kotero mayeso a kukana chisanu konkire ndi mkulu voteji. chiwonongeko akuyamba ndi mbali yotundumukira kunja kwa mpanda, ndipo kenako kupitiriza zigawo chapamwamba ndipo potsiriza likulowerera.

Chimene Iyamba chiwonongeko cha simenti komanso amakhala koyefishienti osiyanasiyana matenthedwe patsogolo zinthu zimene zimapanga nkhani nyumbayi. Izi amalenga nkhawa zina.

Frost kukana konkire chimaonekera mwa njira omwe amalamulira yozizira koopsa ndi thawing ndondomeko. Indicators la magawo mayeso zimadalira zinthu zotsatirazi: kuzizira kutentha, nthawi adzizungulira, kukula kwa nyemba mayeso, njira ya machulukitsidwe madzi. Mwachitsanzo, simenti kumatula ndondomeko amapezeka mofulumira ngati kuzizira zokolola kutentha wotsikitsitsa zotheka mu njira mchere.

Frost kulimbikira konkire ndi ayesedwa pamaso mphindi pamene ena angapo m'zinthu kubwerezabwereza Sakuchepetserani chitsanzo kulemera kwa 5 peresenti ndipo Sakuchepetserani mphamvu yake ndi 25 peresenti. Kuti chiwerengero njira kuti aima zakuthupi nyumba Mzimuyo mtundu wake. Digiri chisanu waperekedwanso malingana m'dera zimene adzagwiritsa ntchito simenti.

Frost Konkire ali ndi dongosolo lapadera. Khalidwe porosity chindiletsa ayezi buku kulenga kuthamanga kwambiri ndi kubweza ndondomeko chiwonongeko.

Chisanu kukana konkire zimadalira chiwerengero cha macropores, kuyambira madzi pores chabwino chotani amaundana ngakhale pa kutentha wotsikitsitsa zotheka, motero kulenga nkhawa zina. Choncho, zimadalira ndi chikhalidwe, mawonekedwe ndi buku la pores lalikulu.

chisanu kukana konkire angathe bwino mu njira izi:

• Kuchepetsa pores lalikulu kuonjezera kachulukidwe konkire.
• Chirengedwe cha mpweya zina pores auzidwa mwa kuyambitsa zina zina. Ngati buku la pores awa adzakhala kotala ya madzi achisanu, sichidzalandiridwa anadzazidwa pa machulukitsidwe yachibadwa. Danga seep madzi unfrozen, ayezi ankatembenukira, kenako zoipazi lafooka.

Buku mkati mwa mpweya chisanu zosagwira konkire akhale peresenti asanu anayi ndi. Kuchuluka kwa mpweya kumadalira osati kokha pa mowa wa simenti ndi madzi, komanso ku akaphatikiza coarse. Voliyumu ya mpweya mu pores mkati mwa konkire ndi chinawonjezeka pamene kuwonjezeka kwa madzi ndi simenti, ndi akaphatikiza kukula tuzigawo twa M'malo mwake, yafupika.
