Kodi chosindikizira konkriti n'chiyani?
- Mankhwala omwe amalowa mu konkriti amakumana ndi simenti yosungunuka pang'ono, calcium yaulere, silicon oxide ndi zinthu zina zomwe zili mu konkriti yokhazikika m'njira zosiyanasiyana zovuta kupanga zinthu zolimba.
- Kalisiyumu yaulere, silicon oxide ndi zinthu zina zomwe zili mu konkriti pambuyo pa zochitika zovuta za mankhwala, zomwe zimapangitsa kuti zinthu zikhale zolimba, mankhwala awa pamapeto pake amapangitsa kuti pamwamba pa konkriti pakhale kukhuthala, motero kulimbitsa mphamvu, kuuma ndi kuuma kwa pamwamba pa konkriti kukhale bwino.
- Mankhwalawa pamapeto pake adzathandiza kuti pamwamba pa konkriti pakhale popyapyala, motero adzakulitsa mphamvu, kuuma, kukana kusweka, kusalowa madzi ndi zizindikiro zina za pamwamba pa konkriti.
Kukula kwa ntchito
- Amagwiritsidwa ntchito popanga pansi yolimba ya mchenga wa diamondi mkati ndi kunja, pansi ya terrazzo, pansi yoyambirira yopukutidwa ndi slurry;
- Pansi panthaka yosalala kwambiri, pansi wamba wa simenti, miyala ndi malo ena oyambira, oyenera ma workshop a fakitale;
- Malo osungiramo katundu, masitolo akuluakulu, malo oimikapo magalimoto, misewu yopita ku eyapoti, milatho, misewu ikuluikulu ndi malo ena okhala ndi simenti.
Makhalidwe a magwiridwe antchito
- Kutseka ndi kusavunda fumbi, kulimba komanso kusawonongeka;
- Kukana kukokoloka kwa nthaka ndi mankhwala;
- Kuwala
- Kuchita bwino polimbana ndi ukalamba;
- Kapangidwe kake kosavuta komanso kosamalira chilengedwe (kopanda utoto komanso kopanda fungo);
- Kuchepetsa ndalama zokonzera, kumanga kamodzi kokha, chitetezo cha nthawi yayitali.
Chizindikiro chaukadaulo
| Chinthu choyesera | Chizindikiro | |
| Mtundu Woyamba (wosakhala wachitsulo) | Mtundu Wachiwiri (wachitsulo) | |
| Mphamvu yopindika ya 28d | ≥11.5 | ≥13.5 |
| Mphamvu yokakamiza ya 28d | ≥80.0 | ≥90.0 |
| Chiŵerengero cha kukana kwa abrasion | ≥300.0 | ≥350.0 |
| Mphamvu ya pamwamba (m'mimba mwake wa indentation)(mm) | ≤3.30 | ≤3.10 |
| Kutuluka kwa madzi (mm) | 120±5 | 120±5 |
