Influence of Superplasticizer Dose on the Behavior of Mortars with Calcium Aluminate Cement : Undergraduate Thesis

U suvremenom građevinarstvu sve je češća primjena aditiva. Razlog njihove primjene je u njihovom povoljnom djelovanju na betone i mortove. U ovom radu istraženo je kako različita doza aditiva „superplastifikator“ utječe na obradivost i čvrstoću morta izrađenog sa kalcij aluminatnim cementom, te kakva su krajnja svojstva tog morta. U eksperimentalnom dijelu napravljene su 4 recepture na kojima je provedeno ispitivanje. Jedna od receptura je napravljena bez aditiva i ona služi kao referenti uzorak, ostale 3 recepture su napravljene sa različitim udjelom aditiva. Na temelju provedenog istraživanja napravljena je usporedba svojstava morta bez aditiva u odnosu na mort sa aditivom. Dobiveni rezultati su obrazloženi te prikazani grafički i tablično te je donesen zaključak.In modern construction work, the use of additives is becoming more common. The reason for their application is in their beneficial effect on concrete and mortar. In this research, it was investigated how the additive „superplasticizer“ affects the flow and strength of mortar made with aluminous cement, and what are the final charactheristic of this mortar. In the experimental part,4 samples were made for testing. One of samples was made without additives and it serves as a reference sample, the other 3 samples were made with different proportions of additive. Based on the conducted research, a comparison of the mortar without additives was made in relation to mortar with additive. The obtained results were explained and presented graphically and tabularly, and a conclusion was reached
