“…The application of this rheological model to column structure elements of HSC, which was observed by Mertol et al (2010) with 7-day heat curing, shows good results with an average error of 6.25% (Figure 5a). Good results (average error for more than 10 days is 3.38%) were also obtained from the application of this rheological model of Choi and Kang (2004) using a high-strength SCC cylinder with 28-day moist curing (Figure 5b). The rheological model for Mertol et al (2010) is double Kelvin-Voigt in series and for Choi and Kang (2004) is triple Kelvin-Voigt in series.…”

“…The large deviation in Phase 1 was 14.1% and 18.3%, which occurred at 8.6 days and 16 days, respectively, while for Phase 2 it was 6.3% (Figure 4b). Mertol et al (2010) and Choi andKang (2004) Mertol et al (2010) observed an HSC column shrinkage. The specimens in this study were cured using a heat-curing system for 7 days.…”

“…The specimens were treated with moisture curing for 28 days. The shrinkage rheological model was applied to both cured types with an average error of 6.25% for Mertol et al (2010) and 3.38% for Choi and Kang (2004). A comparison between both research and the rheological model is shown in Figures 5a and 5b.…”

This paper discusses the shrinkage rheological model of high-performance concrete with a compressive strength of 60 MPa. This is based on experimental research in Indonesia. Three specimens measuring 150 mm × 150 mm × 600 mm were used. Specimens were placed in a conditioned room with a temperature of 28 3oC and relative humidity of 72±5%. Observations were conducted over 7-800 days using an embedded vibrating wire strain gauge for each specimen. As a result, the shrinkage rheological model was single or multi Kelvin-Voigt in series with timedependent disturber flow in it. Disturber flow depends on product hydration growth, weather, pore number, size, and distribution. The model agrees with experimental results. Moreover, it also fits the results using high strength concrete column and high strength self -compacting concrete cylinder.
