A: Emva kokuba ikhonkrithi igalelwe, i-slurry ayikabi namandla, kwaye ukuqina kwekhonkrithi kuxhomekeke ekuqineni kwesamente. Ngokomzekelo, ixesha lokuqala lokubeka i-samente yasePortland yimizuzu engama-45, kwaye ixesha lokugqibela lokumisela iiyure ezili-10, oko kukuthi, ikhonkrithi igalelwe kwaye igudiswe kwaye ibekwe apho ngaphandle kokuphazamisa, kwaye inokuqina ngokukhawuleza emva kweeyure ezili-10. Ukuba ufuna ukunyusa izinga lokumisela ikhonkrithi, kufuneka usebenzise i-generator ye-steam yokunyanga umphunga. Ngokuqhelekileyo unokubona ukuba emva kokuba ikhonkrithi igalelwe, kufuneka igalelwe ngamanzi. Oku kungenxa yokuba i-samente yi-hydraulic cementitious material, kwaye ukuqina kwesamente kuhambelana nobushushu kunye nokufuma. Inkqubo yokudala ubushushu obufanelekileyo kunye neemeko zokufuma kwikhonkrithi ukuze kube lula ukuxutywa kwayo kunye nokuqina kwayo kubizwa ngokuba kukuphilisa. Iimeko ezisisiseko zolondolozo bubushushu kunye nokufuma. Ngaphantsi kobushushu obufanelekileyo kunye neemeko ezifanelekileyo, i-hydration ye-samente inokuqhubeka kakuhle kwaye ikhuthaze ukuphuhliswa kwamandla ekhonkrithi. Ubume bobushushu bekhonkrithi bunempembelelo enkulu kwi-hydration yesamente. Okukhona iqondo lobushushu liphezulu, kokukhona isantya sokugalela amanzi ngokukhawuleza, kwaye ngokukhawuleza amandla ekhonkrithi akhula. Indawo apho ikhonkrithi inkcenkceshelwa khona imanzi, ekulungele ukuqina kwayo.
