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 kubizwa ngokuba yi-curing. 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 sokuqukunjelwa kwamanzi, kwaye ngokukhawuleza amandla ekhonkrithi akhula. Indawo apho ikhonkrithi inkcenkceshelwa khona imanzi, ekulungele ukuqina kwayo.
