Abstract	Cementacija kolona zaštitnih cijevi ovisi o sastavu i svojstvima cementne kaše koja nastaje miješanjem Portland cementa, aditiva i vode. Cementna kaša će kroz reakcije hidratacije s vremenom očvrsnuti u cementni kamen odgovarajuće tlačne čvrstoće i odgovarajućih svojstava. U ovom radu opisani su: bušotinski cement i njegova svojstva, klase cemenata, hidratacija cementne kaše i njeno očvršćavanje u cementni kamen, svojstva cementnog kamena, te su prikazani rezultati laboratorijskih ispitivanja utjecaja kvarcnog praha na svojstva cementne kaše i tlačnu čvrstoću cementnog kamena. Za potrebe ispitivanja korišten je komercijalno dostupan aditiv trgovačkog naziva „Microblock“ koji je suspenzija finog kvarcnog praha u vodi. „Microblock“ se dodaje u cementnu kašu koja se primjenjuje u uvjetima visokih temperatura radi sprječavanja smanjenja tlačne čvrstoće cementnog kamena. Ispitivanja su provedena s pet cementnih kaša s različitim udjelom „Microblocka“ te je prikazan utjecaj „Microblocka“ na tlačnu čvrstoću cementnog kamena, ali i na svojstva cementne kaše.
Abstract (english)	Cementation of casing string depends on composition and properties of cement slurry made by mixing of Portland cement, additives and water. Cement slurry, through reactions of hydration, hardens into set cement that has to be of sufficient strength and of appropriate properties. This thesis describes the properties of cement, well cement classes, hydration of cement slurry and the hardening of cement slurry into set cement. In addition, results of laboratory testing of the way in which silica fume affects the properties of cement slurry and compressive strength of set cement are shown. The commercially available adittive “Microblock“ was used in laboratory testing. This is a suspension of silica fume in water. ”Microblock“ is added during operations in high temperature conditions to prevent set cement compressive strength retrogression. Five cement slurries with diferent amounts of ”Microblock“ have been tested. The results prove that adding the ”Microblock“ affects the compresive strength of set cement as well as the properties of cement slurry.
