"Yamaso Win S" is a curing accelerator that lowers the freezing temperature of concrete and promotes setting and hardening, thereby achieving the strength necessary to prevent initial frost damage. Furthermore, it ensures subsequent strength development, making it suitable for the production and construction of concrete in cold conditions. Additionally, by using AE concrete as a base, it is possible to obtain sufficient resistance to freeze-thaw cycles. 【Features】 - The effect of lowering the freezing temperature of concrete and promoting cement hydration allows for the early acquisition of initial frost resistance and subsequent strength enhancement. - Simple curing methods using curing sheets and other materials can prevent initial frost damage. - By using AE concrete as a base, sufficient resistance to freeze-thaw cycles can be achieved. *For more details, please download the PDF or feel free to contact us.*

"Yamaso 2020R" is a delayed-type slump-retaining agent that significantly improves the slump and slump flow retention performance during transportation (such as pumping) without almost affecting the initial slump or air content of the base concrete. It has setting delay properties, ensuring the fluidity of concrete even during extreme heat, which helps prevent poor filling and the occurrence of cold joints. Additionally, by adjusting the amount used, the slump retention performance of the concrete can be controlled as desired. 【Features】 ■ Meets the standards required for admixtures in the Concrete Standard Guidelines for "Hot Weather Concrete above 35°C" ■ Capable of reducing slump loss in concrete during extreme heat ■ Possesses setting delay properties, helping to prevent poor filling and the occurrence of cold joints ■ A non-chloride type slump-retaining agent that does not contain chlorides *For more details, please download the PDF or feel free to contact us.

"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).
