Study of the Application of Viscosity Reducing Type Superplasticizers for Low Water-Binder Ratio Concrete

This paper describes how in low-water/binder-ratio concrete such as high-strength concrete (HSC) or self-compacting concrete (SCC), concrete workability decreases due to the high viscosity of the concrete as a result of its mixture components and proportion. It is considered that a reduction in concrete viscosity is significantly advantageous for placement of HSC or SCC. In this study, the authors add viscosity reducing type superplasticizers to the formulation of low-water/binder-ratio concrete. As a result, it is found that viscosity reducing type superplasticizers can reduce the viscosity of cement paste in concrete; moreover, the time to achieve a 500 mm (19.7 in.) slumpflow (an index of concrete workability) can be reduced. Accordingly, it is confirmed that application of viscosity-reducing superplasticizers can effectively improve the workability of HSC or SCC.
