Izotermna kalorimetrija u\u010dinkovit je alat za prou\u010davanje stupnjeva povezanih s hidratacijom cementnih pasta ili mortova pri konstantnoj temperaturi. Kalorimetar kontinuirano mjeri i prikazuje protok topline povezan s reakcijama hidratacije koje se odvijaju u cementnoj pasti nakon mije\u0161anja.<\/p>\n\n\n\n

Primjer upotrebe<\/strong>: Toplinski protok i toplina hidratacije cementne paste primijenjene u tunelu – za potrebe primjene nove vrste cementa na gradili\u0161tu, zahtijevao se podatak o ukupnoj oslobo\u0111enoj toplini hidratacije<\/p>\n\n\n\n
Hidratacija cementa je egzotermna reakcija koja se odvija u nekoliko faza, vidljiva na krivulji kalorimetrije:<\/p>\n\n\n\n
Slika 1 prikazuje tijek reakcije u prvih 50 sati. Razdoblje ubrzanja karakterizira glavni “peak” u kalorimetrijskoj krivulji, koji se uglavnom pripisuje silikatnoj reakciji, tj. stvaranju C-S-H gela i kalcijevog hidroksida (Ca(OH)2<\/sub>). Mo\u017ee se primijetiti jo\u0161 jedan ne\u0161to manji vrh, oko 16 sati nakon po\u010detka reakcije. Ovaj vrh ukazuje na otapanje aluminata (C3A) i naknadno stvaranje etringita.<\/p>\n\n\n\n<\/figure>\n","protected":false},"excerpt":{"rendered":"
