The Influence of Admixtures on the Technological Properties of Fresh Concrete Mixture

Abstract: In this research superplasticizing (SP), air voids removing (AVR), viscosity modifying (VM) and air entraining admixtures (AE) were used. The dosage of admixtures was chosen from minimum to maximum values recommended by the manufacturers. To sum up, 7 concrete mixture compositions with SP, 6 with AVR and 6 with VM and the last 6 with AE admixture were prepared. Water and cement ratio for all the compositions was kept at the same value. According to the results obtained, the usage of SP admixture resulted in si… Show more

“…The technological properties of the concrete mixture are related to its rheological properties and therefore it is easier to establish the yield stress of the concrete from its slump and density. The yield stress of concrete mixtures was evaluated using Equation (2), and was also adopted by other authors in their research [29][30][31][32]…”

“…The plastic viscosity of the concrete mixture was evaluated using Equation 3, which was also adopted by other authors in their research [28,29,31,32] Concrete was mixed in accordance to LST EN 206 [23] using dry materials. The concrete mixtures were prepared in the laboratory using a forced type Pemat Mischtechnik GmbH (Freisbach, Germany).…”
