The influence of different mixing ratios of ordinary and aluminate cement on binding speed : Undergraduate Thesis

U ovom radu je ispitana brzina vezanja cemente paste s različitim omjerima običnog i aluminatnog cementa. Tijekom pripreme uzoraka i uspoređivanja rezultata dobiven je omjer za cementnu pastu standardne konzistencije s najoptimalnijim vremenom vezanja. Za ispitivanja je korišten komercijalni aluminatni cement (AC) Istra 40 i bijeli dekorativni cement CEM I 52.5 R. Vrijeme početka vezanja određivano je standardnim Vicatovim testom.The binding speed of cement paste with different ratios of ordinary and aluminate cement was investigated in the present work. During the preparation of specimens and the comparison of results, the standard consistency cement paste ratio with the most optimum binding time was acquired. Commercial aluminate cement (AC) Istra 40 and white decorative cement CEM I 52.5 R were used during the research. The initial time of binding was determined by a standard Vicat test
