Izicelo kunye neentlobo zoMdaka

Udaka sisixhobo sokwakha esisetyenziselwa ukubopha izitena, amatye, kunye nezinye iiyunithi zobumba kunye. Ngokuqhelekileyo iqulunqwe ngumxube wesamente, amanzi, kunye nesanti, nangona ezinye izinto ezifana nekalika kunye nezongezo zinokubandakanywa ukuphucula iimpawu zayo. Udaka lusetyenziswa kwiintlobo ngeentlobo zezicelo zokwakha, ukusuka ekubekeni izitena zodonga oluncinane lwegadi ukuya ekwakhiweni kwezakhiwo zorhwebo ezinkulu. Kweli nqaku, siza kuxubusha iintlobo ezahlukeneyo zodaka kunye nokusetyenziswa kwazo.

1. Chwetheza Udaka lwe-N

Udaka lwe-N ludaka lwenjongo jikelele oluqhele ukusetyenziswa kwiindonga zangaphandle, iitshimini, kunye neendonga ezingathwali mthwalo. Yenziwe ngesamente yasePortland, ikalika ene-hydrated, kunye nesanti, kwaye inamandla okucinezela aphakathi. Udaka lwe-N lusebenza lula kwaye lubonelela ngamandla okudibanisa.

2. Uhlobo lwe-S Udaka

Uhlobo lwe-S ludaka ludaka oluphezulu olusetyenziswa ngokuqhelekileyo kwizicelo zesakhiwo ezifana neendonga ezithwele umthwalo, iziseko kunye neendonga zokugcina. Yenziwe ngesamente yasePortland, ikalika ene-hydrated, kunye nesanti, kwaye inokubandakanya izongezo ezifana ne-pozzolans kunye neentsinga zokuphucula amandla kunye nokuqina.

3. Chwetheza uMdaka

Uhlobo lodaka lwe-M lolona hlobo lunamandla lodaka kwaye luqhele ukusetyenziswa kwizicelo zomthwalo onzima ezifana neziseko, iindonga ezigcinayo, kunye neendonga zangaphandle eziphantsi kweemeko zemozulu ezinzima. Yenziwe ngesamente yasePortland, ikalika ene-hydrated, kunye nesanti, kwaye inokubandakanya izongezo ezifana ne-pozzolans kunye neentsinga zokuphucula amandla kunye nokuqina.

4. Uhlobo lwe-O Mortar

Uhlobo lwe-O ludaka ludaka oluphantsi olusetyenziswa ngokuqhelekileyo kwiindonga zangaphakathi kunye nezingathwali umthwalo. Yenziwe ngesamente yasePortland, ikalika enamanzi, kunye nesanti, kwaye inamandla aphantsi oxinzelelo. Uhlobo lwe-O lodaka kulula ukusebenza kunye kwaye lunikeza amandla okudibanisa okulungileyo.

5. Udaka lwekalika

Udaka lwekalika ludaka lwemveli olwenziwe ngekalika, isanti namanzi. Iqhele ukusetyenziswa kwiiprojekthi zokubuyiselwa kunye nokugcinwa kwembali ngenxa yokuhambelana kwayo neeyunithi zembali zamatye. Udaka lwekalika lukwasetyenziswa kwizicelo zolwakhiwo ezitsha zokuqina, ukuphefumla, kunye nokuguquguquka.

6. Udaka lweMasonry Cement

Udaka lwesamente lweMasonry ludaka oludityaniswe kwangaphambili oluqulunqwe ngesamente eyenziwe ngamatye, isanti kunye namanzi. Iqhele ukusetyenziselwa ukwenza izitena kunye nezinye izicelo zokumisa ngenxa yokuqina kwayo okuphezulu kunye nokusebenza.

7. Udaka olunombala

Udaka olunombala ludaka oludaywe ukuze lutshatise okanye luthelekise nombala weeyunithi zobumba. Isetyenziswa ngokuqhelekileyo kwizicelo zokuhombisa ukunyusa isibheno sobuhle besakhiwo. Udaka olunemibala lunokwenziwa kulo naluphi na uhlobo lodaka kwaye lunokuxutywa ukufezekisa uluhlu olubanzi lwemibala.

Ukuqukumbela, kukho iintlobo ezininzi zodaka olukhoyo kwizicelo ezahlukeneyo zokwakha. Kubalulekile ukukhetha uhlobo olufanelekileyo lodaka lomsebenzi ukuze kuqinisekiswe ibhondi eyomeleleyo kunye neyomeleleyo phakathi kweeyunithi zobumba. Umashi oqeqeshiweyo okanye ikontraki inokunceda ukumisela uhlobo olufanelekileyo lodaka olunokusetyenziswa ngokusekelwe kwiimfuno ezithile zeprojekthi.
