Kodi nthawi yoyenera kugwiritsa ntchito konkriti ndi iti?
Chotsukira cha konkriti chingathandize kuti pansi pakhale pachangu, pathyathyathya komanso pakhale pabwino, koma pokhapokha ngati chalowa mu slab panthawi yoyenera. Ngati makinawo ayamba msanga, poto kapena masamba ake akhoza kusokoneza konkriti yofewa. Ngati yayamba mochedwa, pamwamba pake pamakhala povuta kutseka ndipo wogwiritsa ntchitoyo ayenera kugwira ntchito ngati akuyesera kupukuta mwala.
Kwa makontrakitala, oyang'anira malo ndi ogula zida, nthawi yogwiritsira ntchito trowel ndi yofunika kwambiri monga mphamvu ya injini, kukula kwa ntchito kapena mtundu wa tsamba. Makina abwino sangapulumutse nthawi yoyipa, koma nthawi yoyenera ingathandize makinawo kugwira ntchito bwino kwambiri.
Chifukwa Chake Kufunika kwa Nthawi Pomaliza Pansi pa Konkire
Kumaliza konkriti sikulamulidwa ndi wotchi yokha. Kumayendetsedwa ndi liwiro lokhazikitsa, kapangidwe kake kosakanikirana, makulidwe a slab, nyengo, mphepo, kutentha, chinyezi komanso kuchuluka kwa madzi omwe amatuluka pamwamba. Ma slab awiri omwe amathiridwa tsiku lomwelo amatha kukonzedwa nthawi zosiyanasiyana, makamaka ngati imodzi ili padzuwa ndipo inayo ili pamthunzi. Ichi ndichifukwa chake ogwiritsa ntchito odziwa bwino ntchito amaonera konkriti kwambiri kuposa momwe amaonera mafoni awo.
Kuyambira makina opangira magetsi Zingathe kutseka pamwamba pa nthaka mpweya ndi madzi otuluka magazi asanatuluke. Bungwe la National Ready Mixed Concrete Association akufotokoza kuti kugawanika kwa madzi kungachitike pamene pamwamba patsekedwa ndi kumalizidwa msanga pomwe mpweya kapena madzi otuluka magazi amakhalabe pansi. Mwachidule, pamwamba pa denga lingawoneke ngati latha, koma pansi pake pamakhalabe kuyesera kupuma.
Mfundo yochokera ku umboni: kutsuka chitsulo msanga si vuto laling'ono lokongoletsa. Netiweki ya Konkire Amafotokoza kuti pamene kumaliza kumayamba msanga kwambiri ndipo kutseka pamwamba pa denga lisanatuluke, mpweya kapena madzi zimatha kutsekeredwa pansi pa denga lolimba, zomwe zimapangitsa kuti pamwamba pa denga pakhale mipata yambiri.
