Chomera chomera chaimu

Njira inanso yokongoletsera makoma ndi ntchito yamkati yokhala ndi laimu. Amagwiritsidwa ntchito poyang'ana makoma opangidwa ndi konkire yowonongeka, konkire ndi njerwa . Sitikugwiritsanso ntchito mapaipiwa pamapangidwe opangidwa ndi pepala ndi matabwa, komanso malo omwe ali pamtundu uliwonse.

Kuyika kwa pulasitala yamchere

Taganizirani za mapangidwe a simenti. Zachigawozikulu za nkhaniyi ndi simenti, laimu ndi mchenga. Malingana ndi cholinga cha kugwiritsa ntchito, chiŵerengero cha kuchuluka kwa zigawo zikhoza kusintha. Komanso, mukhoza kugula matope owuma pamsika ndikungowonjezera madzi kuti ayambe, kapena mungathe kudzipanga nokha. Pachifukwa ichi, mudzatha kufotokozera momveka bwino momwe mukufunira. Mwachitsanzo, kuchepa kwa gawo la simenti ndi kuwonjezeka kwa chiwerengero cha laimu, zinthuzo zidzataya mphamvu zake, ndipo pang'onopang'ono kuwonjezera nthawi yovuta.

Zomangamanga zimakhala ndi simenti-lime plasters

Makhalidwe abwino a simenti-lime plasters ndi awa:

1. Nthawi yogwiritsira ntchito njira yothetserayi ikuchokera pa ora limodzi mpaka awiri. Zimadalira wopanga komanso chiwerengero cha zigawo zomwe zimagwiritsidwa ntchito.
2. Kuthamanga kapena mphamvu zothandizira pa khoma sizoposa 0.3 MPa.
3. Mphamvu zowonjezereka zopambana ndizosiyana ndi 5.0 MPa.
4. Kutentha kotentha -30 ° C mpaka 70 ° C. Malingana ndi njirayi, njira zoperekera zimaperekedwa. Izi sizikutanthauza kuti nthawiyi ndi yofunika kwambiri pa miyala ya mandimu ndi simenti ndi mphamvu iliyonse.
5. Zomwe akugwiritsa ntchito pamtunda umodzi wa mamitala kuchokera 1.5 kg mpaka 1.8 makilogalamu m'kati mwake 1 mm.
6. Kusungirako kuli m'thumba. Komabe, pamene mutsegula thumba, ndibwino kuti muzigwiritsa ntchito mwamsanga. Popeza kuti zimakhudzidwa ndi zinthu zachilengedwe zomwe zimapangitsa kuti zinthu zifike kumalo osayenera kugwiritsa ntchito (mwachitsanzo, zovuta kuchokera ku chinyezi).

Tikulimbikitsidwa kugwira ntchito ndi matope a simenti pamatentha otentha kuchokera pa + 5 ° C mpaka 30 ° C. Ndipo chifukwa cha kutentha kwa mpweya osachepera 60%. Ndi bwino kuti panthawi yowuma ndi kuuma kwa chophimba kudzakhala kotheka kusunga chinyezi mu 60% mpaka 80%. Pofuna kupaka chipinda chamkati, ziyenera kukhala mpweya wokwanira kawiri pa tsiku, izi zidzathandiza kuumitsa kwadothi lamchere.
