Using various dosages of LC and PCE, tests for fluidity, setting time, mechanical properties, hydration heat, adsorption and chemically bound...

...%. Rheologically, finer GFA improved mortar fluidity by 11.0% and significantly reduced cement paste yield stress and plastic viscosity by 73.3% and 39.1%, respectively. However, SFA demonstrated superior rheological performance at similar fineness due to higher sphericity, underscoring the critical role...
