マルアイ石灰工業 List of Products and Services

"Neo Soil Aqua (NS-AQ)" is a dust suppression type ground improvement material. By incorporating inorganic materials, it demonstrates high strength across a wider range of soil types compared to conventional products. Additionally, since it is non-cement-based, there is no need for hexavalent chromium leaching tests. It can be used in situations where it is necessary to suppress dust, such as near residential areas. Please feel free to contact us when you need it. 【Detailed Data】 ■ Type: Ground improvement material ■ CaO: 60-70% ■ Applicable water content ratio: 10% - 50% low water content ratio ■ Heat generation: None ■ Packaging: FIBC *For more details, please download the PDF or feel free to contact us.

"Neo Soil LG (NS-LG)" is a quick-setting lime-based solidifying agent. It improves soil quality in a short period through rapid dehydration. Additionally, since this product is non-cement based, it does not require hexavalent chromium leaching tests. Please feel free to contact us when you need it. 【Detailed Data】 ■Type: Ground Improvement Material ■CaO: 70.0% or more ■Applicable Water Content Ratio: 20% or more, high water content ratio ■Heat Generation: Yes ■Packaging: Spread/Frecon *For more details, please download the PDF or feel free to contact us.

"TAFROX SUPER (TL-S)" is a cement-lime composite solidification material that combines the characteristics of both cement and lime, suitable for the improvement of high moisture content soils such as loam, clayey soils, and construction waste soils, while reducing hexavalent chromium leaching. Thanks to the heat generation from lime hydration, it is possible to achieve early strength development of the cement. The heat generation from hydration rapidly decreases the moisture content in the soil, improves consistency by granulating soil particles, and is expected to enhance compaction effects. 【Detailed Data】 ■ Type: Ground improvement material ■ Applicable moisture ratio: 20% or more, high moisture ratio ■ Heat generation: Yes ■ Packaging: Spread/Frecon ■ Remarks: As it is cement-based, hexavalent chromium leaching tests are not required. *For more details, please download the PDF or feel free to contact us.

"Neo Soil LS (NS-LS)" is our original lime-based high-strength solidifying agent. This product exhibits rapid solidification reactions, allowing for compaction after application. Additionally, since it is non-cement based, there is no need for hexavalent chromium leaching tests. It can be used for the regeneration of construction sludge and dredged soil. 【Detailed Data】 ■ Type: Soil improvement material ■ CaO: 55-85% ■ Applicable water content ratio: 20% or more, high water content ratio ■ Heat generation: Yes ■ Packaging: Spread/Frecon ■ Size: Powder form *For more details, please download the PDF or feel free to contact us.

"Quicklime" is made by calcining limestone, and its main component is calcium oxide (CaO). (CaCO3 → CaO + CO2) Applications include use in steelmaking, pH adjustment in water treatment plants, prevention of red water, sludge treatment, and sewage and wastewater treatment. It can also be used as a source of alkali for food, as fertilizer, and in construction materials.
