The application range of ordinary cement is limited as a grouting material due to the material particle size, which has a maximum size of 90 μm and an average size of 10 to 20μm.
However, SUPERFINE has the advantage of an average particle size of 4μm and can be injected into fine sand layers and micro-fissures, which previously had been ungroutable with ordinary cementitious grouting material.
As a pioneer in the field of Ultrafine cementitious grouting, SUPERFINE has achieved a high level of success in numerous grouting projects in Japan and overseas.

Penetration into microfissures

SUPERFINEULTRAFINE CEMENT

Characteristics

SUPERFINE is a blast furnace slag-based ultrafine cementitious grout material with a D95 particle size of approximately 10μm.
It is able to permeate fine sand and grout very small cracks and fissures. It is used in various grout applications for dams and tunnels.

Use

• 1. Pre-and post -excavation grouting
• 2. Water cut-off grouting
• 3. Dam grout curtain
• 4. Soil consolidation
• 5. Stabilization of structure foundation

SUPERFINE-LULTRAFINE CEMENT FOR HYDROTHERMAL and / or BRINY CONDITIONS

Characterristics

SUPERFINE-L is a Blast furnace slag-based ultrafine cementitious grout material specifically for hydrothermal and / or seawater-saturated ground that would be difficult to grout with traditional cementitious materials.
It is used in various grout applications at harbors, isolated islands, hydrothermal and coastal areas in Japan.

Use

• 1. Seismic reinforcement and liquefaction countermeasure applications for structures around coasts and harbors
• 2. Grout works for seawater-saturated sandy ground and hydrothermal areas
• 3. Sand solidifications for caisson construction

HNP-1500NANOFINE CEMENT WITH D50≒1.5μ

＊Prior consultation is required as production and sales of the product for special applications.

Characteristics

HNP-1500 is a nanofine cement with an average particle size of 1.5μm, which is finer than SUPERFINE ultrafine cement.
Its small particle size allows it to permeate ground containing fine sand mixed with silt that would be difficult to grout using ultrafine cement.

Use

• 1. Liquefaction and seismic reinforcement of foundations, underground structures and directly under existing structures
• 2. Reinforcement of embankments and slopes
• 3. Grout works for tunnels and other underground facilities
• 4. Foundation improvement projects requiring high strength
