"Yamaso 2020" is a non-chloride, non-chlorinated type of slump retaining agent. It can significantly improve the slump and slump flow retention performance during transportation to the site and within the site (such as pumping), with minimal impact on the initial slump and air content of the base concrete. Additionally, by adjusting the amount used, the slump retention performance of the concrete can be controlled as desired. 【Features】 ■ Improves slump retention performance without delaying the start and end times of setting compared to the base concrete. ■ Allows for arbitrary control of the concrete's slump retention performance by adjusting the amount used. ■ Does not significantly increase the bleeding amount compared to the base concrete. *For more details, please refer to the PDF materials or feel free to contact us.

Yamaso V1-DS and V1-DSR are a new type of high-performance AE water-reducing agents that not only possess the excellent cement dispersion and slump retention characteristics of conventional high-performance AE water-reducing agents but also have shrinkage reduction capabilities, making them a one-component solution. By adding shrinkage reduction capabilities, it is possible to reduce the drying shrinkage strain of concrete, enabling the production of high-quality, durable concrete with fewer cracks. 【Features】 ○ Reduces drying shrinkage strain by approximately 5 to 15% compared to concrete using conventional high-performance AE water-reducing agents. ○ Low viscosity of concrete improves pumpability and workability. ○ By combining with Yamaso Chemical's unique air content adjusting agent, it is possible to control fluctuations in air content over time. ○ Yamaso V1-DS: Complies with JIS A 6204 "Chemical Admixtures for Concrete" high-performance AE water-reducing agent standard type (Type I). ○ Yamaso V1-DSR: Complies with high-performance AE water-reducing agent delayed type (Type I).
