1. Nkhani yogwiritsa ntchito madzi
Pokonzekera konkire yogwira ntchito kwambiri, chidwi chiyenera kuperekedwa posankha slag yabwino ndikuwonjezera phulusa lalikulu la ntchentche. The fineness admixture adzakhudza madzi kuchepetsa wothandizila, ndipo pali mavuto ndi khalidwe la admixture, amene mosalephera kukhudza ntchito ya konkire. Ngati kusinthasintha kwa slag kuli bwino, kuchuluka kwa kusakaniza kuyenera kukhala kwakukulu, mwinamwake kungayambitse mavuto a magazi. Ndikofunikira kuwongolera kuchuluka kwa phulusa la ntchentche mu konkire kuti muwonetsetse kuti chochepetsera madzi chimakhala ndi gawo labwino.

2. Kusakaniza kuchuluka kwa nkhani
Kugawidwa koyenera kwa phulusa la ntchentche ndi slag kumatha kupititsa patsogolo ntchito ya konkire, kuchepetsa kugwiritsa ntchito simenti pomanga uinjiniya, komanso kuchepetsa ndalama zakuthupi. Ubwino ndi khalidwe la admixture lidzakhudza mphamvu ya madzi kuchepetsa wothandizira. Kupititsa patsogolo ntchito ya konkire kumafuna zofunikira zina za fineness ndi khalidwe la admixture. Pokonzekera konkire yogwira ntchito kwambiri, kugwiritsa ntchito ufa wa slag mu admixture kungapangitse ntchito yake. Kuchuluka kwa admixture kuyenera kukhazikitsidwa molingana ndi momwe zinthu ziliri, ndipo mlingo uyenera kuyendetsedwa.

3. Mlingo wa mankhwala ochepetsa madzi
Kugwiritsa ntchito zinthu zochepetsera madzi mu konkire yamalonda kumafuna kumvetsetsa kwasayansi kuchuluka kwa zochepetsera madzi zomwe zimagwiritsidwa ntchito komanso kuwongolera koyenera kwa magawo awo. Sankhani mitundu yosiyanasiyana yochepetsera madzi potengera mtundu wa simenti mu konkire. Muzomangamanga, mlingo wa ochepetsa madzi uyenera kutsimikiziridwa pambuyo poyesedwa kangapo kuti apeze dziko labwino.

4.Kuphatikiza nkhani
Zomwe zimagwiritsidwa ntchito mu konkire ziyenera kuyesedwa kuchokera kuzinthu zingapo, ndi zizindikiro zazikulu zowunikira kuphatikizapo mawonekedwe, tinthu tating'onoting'ono, mawonekedwe a pamwamba, matope, matope a konkire, ndi zinthu zovulaza zomwe zili. Zizindikirozi zidzakhala ndi zotsatira zina pa khalidwe lamagulu, ndipo chidwi chapadera chiyenera kuperekedwa kwa matope. Zomwe zili mumatope mu konkire sizingadutse 3%, mwinamwake ngakhale ngati zochepetsera madzi zikuwonjezeredwa, ubwino wa konkire sungathe kukumana ndi muyezo. Mwachitsanzo, pulojekiti ina yomanga imagwiritsa ntchito konkriti ya C30. Pakuyesa kusakaniza konkire, pamene chiŵerengero chochepetsera madzi ndi 1%, chingathe kukwaniritsa zofunikira zaumisiri, kuphatikizapo fluidity, kuwonjezereka kwa slump, etc. zofunikira za uinjiniya kapena kukwaniritsa miyezo yodziwika. Pambuyo pofufuza ndi kusanthula kwa akatswiri, zinatsimikiziridwa kuti chifukwa chachikulu cha chochitika ichi ndi chakuti matope omwe ali mumagulu abwino amaposa 6%, zomwe zimakhudza kuchepetsa madzi. Komanso, akalumikidzidwa osiyanasiyana coarse akaphatikiza particles zingakhudzenso madzi kuchepetsa zotsatira za madzi kuchepetsa wothandizila. Kuchuluka kwa konkriti kudzachepa ndi kuchuluka kwa zida ndi zophatikiza zazikulu. Pambuyo pofufuza zasayansi, sikokwanira kudalira kokha othandizira kuchepetsa madzi kuti apititse patsogolo zotsatira za konkire ndikuwonjezera mphamvu zake. M'pofunika kukhathamiritsa kusakaniza konkire kuti tikwaniritse zotsatira zabwino.
