Mmodzi mwa makasitomala athu anandifunsa kuti: 'Kodi kupanga kwanu kukuyenda bwanji?

zomwe zimandipangitsa kuzindikira kuti kuteteza zachilengedwe ku China kuli ndi vuto lalikulu pazamankhwala monga konkriti ku China.

Ndiroleni ndikudziwitseni kuyambira pachiyambi.

Monga tonse tikudziwa, China ikukula mwachangu zaka izi, pomwe vuto la chilengedwe likukulirakulirakulirakulira, chifukwa cha kuphatikiza konkriti, monga sodium naphthalene formaldehyde, polycarboxylate superplasticizer, ndi zina zambiri ndipo kupanga kwawo kwazinthu zopangira kumabweretsa kuwononga madzi ambiri ndi mpweya.

Monga m'badwo wachiwiri konkire admixture, sodium naphthalene formaldehyde, zopangira zake, pali mafakitale kalasi naphthalene ndi formaldehyde.besides, pa kupanga, pali zambiri fungo la pungent ndi tinthu fumbi.

Monga zosakaniza zaposachedwa za konkriti, polycarboxylate superplasticizer, nthawi zonse pamakhala fungo lachilendo kuzungulira chomera cha polycarboxylate superplasticizer.

Boma la China layamba kuzindikira kuti iyi si njira yoyenera yopititsira patsogolo chuma.ayamba kukhazikitsa gulu loyang'anira zachilengedwe kuti athetse vuto la kuipitsa.

Monga imodzi mwamafakitale olemetsa oyipitsidwa, malo opangira konkriti ophatikizana osakanikirana opanda chilolezo chabizinesi kapena popanda njira yoyenera yoletsa kuyipitsa anakakamizika kuzimitsa.

izi kumabweretsa mtengo konkire admixture kuwonjezeka quickly.some konkire admixture fakitale ndi malamulo, koma palibe zopangira zokwanira kupanga.

Pomaliza, kuti ndikutsimikizireni, inde, kupanga kwathu kumakhala kokhazikika pakusakaniza konkriti.
