Introducing a ground improvement additive made from glass powder!
"Earth Silica" is a ground improvement additive used by adding it to blast furnace slag fine powder. It is a mixture of glass powder containing a large amount of silica and alkaline additives, which promotes the solidification of blast furnace slag fine powder and forms a solidified body that achieves high strength. Furthermore, by partially replacing some of the blast furnace slag fine powder with calcium, it is possible to control the time until the effect is realized. 【Features】 ■ With zero cement, the CO2 emissions as a solidifying agent can be reduced by 80% compared to ordinary Portland cement. ■ Since it does not contain chromium compounds, there is no concern about hexavalent chromium leaching. ■ In improved soil, strength greater than that of cement-based solidifying agents can be achieved. ■ Dramatic effects are obtained in the strength development of clayey soil. ■ High fluidity is achieved when mixing with slurry of clayey soil. *For more details, please refer to the PDF materials or feel free to contact us.

Company information
Our company was founded in 1973 and is based in Sendai City, primarily focusing on ground surveys. We are dedicated to observing (watching), diagnosing (analyzing phenomena), investigating (researching), and measuring (assessing) while actively working across various prefectures in the Tohoku region for many years. As a group of engineers engaged in "geological survey operations," we promote awareness of geological risks related to ground and groundwater caused by disasters, and we continuously refine technologies that are resilient to disasters and also contribute to disaster reduction. Please feel free to contact us if you have any requests.
