We have developed an environmentally friendly powder accelerator called "Bisco Shot" in collaboration with Kao Corporation. "Bisco Shot" is a powder accelerator that reduces rebound during shotcrete application in mountain tunnel construction by incorporating a special thickening function. It is expected to offer benefits such as cost savings on materials, reduced work burden, and decreased CO2 emissions through the reduction of shotcrete usage. Please refer to the attached document for more details.

The dry spray application method "Air Shot One" has been registered in the Ministry of Land, Infrastructure, Transport and Tourism's New Technology Information System NETIS. NETIS Registration Number: KK-240029-A Air Shot One is a dry spray method that performs section restoration by mixing and spraying mortar powder, which is pumped with compressed air, and water, which is pumped through a nozzle. Traditionally, wet spray methods were used, but the use of this technology eliminates the need for mixing mortar, thereby improving workability, cost-effectiveness, quality, working environment, and shortening the construction process. The mortar powder is suitably formulated with cement, fine aggregates, various admixtures, and powdered polymers, resulting in a mortar that excels in durability and thickness application. Additionally, it allows for a spraying application rate of 1 cubic meter per hour, significantly improving the daily construction volume.

Contractors can earn additional points in construction performance evaluations by utilizing technologies registered in NETIS for public works projects.*
