Composite cements with heat-convertible polymer - preparation and parameters
 Surman, František ; Šiler, Pavel (referee) ; Havlica, Jaromír (advisor)
This bachelor’s thesis deals with the preparation and study of composite material based on thermosetting polymer (phenol resin) and inorganic binder (high alumina cement). Very high mechanical properties, considerable stability to moisture and heat are specific properties of this polymer-cement composite. The special preparation means high-shear mixing, which depends resultant properties of composite to a considerable extent. Theoretical part reveals the reason of high achievements, which are typical for this polymer-cement composite but not for other type of inorganic binder used in this composite. This part furthermore studies chemical and physical processes, which occurs in composite mixture during processing and hardening, environmental durability and general applications of polymer modified cements. Practical part includes the laboratory preparation of phenol resin and the study of flexural strength of composite according to resin content in composite mixture. The flexural strength was measured by universal test machine Zwick Z010. Microstructure of material was observed by optical microscopy.
