Self-Compacting Concrete Mix Design Procedure. Designing a self-compacting concrete mix requires careful consideration of various factors, including the desired fresh and hardened properties, the specific application, and the availability of materials. The following steps outline the general process for designing an SCC mix:

Abstract. This paper focuses on the possibility of using calcareous tuff (CT) in self-compacting concrete (SCC) production. In concrete mixtures, CT is used as sand and its fines as partial cement replacement. Mixtures are prepared with three different sand/mortar ratios (S/M) of 0.40, 0.45 and 0.50 with a varying superplasticiser content …

Tomosawa ("Toward Mix Design for Rheology of Self-Compacting Concrete", Proceedings of the First RILEM International Symposium on Self-Compacting Concrete, pp. 361-372, 1999), and can in the majority of cases explain the changes observed in SCC rheological properties resulting from changes to the material composition.

Step 3: determine the mixing water content required by cement. According to the experience of the Ready-Mixed Concrete in Taiwan, the water/cement ratio of SCC produced with FA and GGBS is about 0.43 for obtaining f ′ c =4000 psi for 28 days. Amount of mixing water needed for cement: W wc =0.43×200=86 kg / m 3. 3.4.
