Bio-Derived Rheology Modifying Agents for Cement-Based Materialsgy Modifying Agents (RMAs) (such as superplasticizers) and Viscosity Modifying Agents (VMAs) have been developed as two alternative admixtures to obtain the required workability. However, these admixtures not only increased the environmental impacts of concrete production but also increased the unit

Influence of Cements Containing Calcareous Fly Ash on Rheological Properties of Fresh Mortars and Ities of mortars and its variability is presented. In comparison to mortars with CEM I mortars with cements CEM II/A-W, CEM II/B-W, CEM IV/B-W are characterized by worse workability and faster workability loss, the greater the more fly ash W is in cement. However, using cements CEM II/A-W, CEM II/B-W

Influence of Different Accelerators on the Rheology and Early Hydration of Cement Pastet time steps during the casting process. Superplasticizers such as polycarboxylate ethers (PCE) can be used to obtain the required flowability, which, possibly in combination with additional rheology modifying admixtures, generate the required specified consistency. However, after the application, t

Effect of Mineral Additions on Rheology and Fresh Properties of Cement Pastes and Mortarslimestone powder LP. One type of cement CEM I 42.5R and one high range water reducing (HRWR) admixture were used in all mixes. Fresh properties of mortars with natural postglacial sand 0/4 mm were examined by mini-cone test and rotational viscometer Viskomat XL. In this instrument, when the cylindri
