麻生フオームクリート List of Products and Services

We would like to introduce various construction methods for the measures against "sinkholes caused by the deterioration of underground cavities and sewer pipes" proposed by our company. Starting with the "Bubble Concrete Method," which uses civil engineering materials that incorporate air bubbles into slurry-like mortar, we also offer the "NLG Method" using non-air grout materials, and the "Air Pack Method," which is suitable for backfilling injection in conditions of spring water, standing water, and flowing water. Additionally, we handle the premixed type air mortar "Light Fill Foam," which can be used simply by mixing with water. 【Examples of Measures】 ■ Bubble Concrete Method - Allows for flexible design of strength and density, enabling long-distance pumping with a pump. - High workability, making it easy to construct on steep slopes and other challenging terrains. - Low permeability and excellent long-term durability. ■ NLG Method - Excellent filling capability, allowing for long-distance pumping up to 5,000 meters. - High non-leakage and non-shrinkage properties. ■ Air Pack Method - Water-resistant air mortar with high applicability in water environments. - Capable of uniform strength and stable injection. ■ Premixed Air Mortar - Can be used simply by mixing with water. - Effective for small-scale projects and confined spaces. *For more details, please download the PDF or feel free to contact us.

While leaving the bridge piers and girders intact, we will fill the voids beneath the bridge with aerated concrete to convert it into an earth structure. This will eliminate the need for regular inspections and repairs of the buried bridge, contributing to its longevity and also resulting in reduced running costs thereafter. Additionally, since the work will be carried out only in the space beneath the bridge, there is no need for external scaffolding for the assembly of formwork panels, allowing construction to proceed without completely closing the road to traffic. In an era where maintaining and managing existing infrastructure to extend its lifespan is essential, our air mortar technology will respond to the needs of the times.

• Bridge Construction

"Light Fill Foam" is a premixed type of air mortar that only requires water to be mixed. Due to the lightweight and fluidity characteristics of air mortar, it is suitable for cavity filling, and high-quality air mortar manufacturing and filling work can be carried out using a dedicated plant. The compactly designed dedicated plant enables construction in small-scale projects and narrow areas, which were previously less applicable. [Features] ■ Just mix with water ■ Ideal for cavity filling due to lightweight and fluidity ■ Achieves high-quality filling by using a dedicated plant ■ Effective for small-scale projects and narrow areas *For more details, please refer to the PDF materials or feel free to contact us.

The "FCB Method" is a construction technique that uses bubble-mixed lightweight soil as fill material, leveraging the characteristics of bubble-mixed lightweight soil (air mortar, air milk) such as lightweight, fluidity, and self-supporting properties. It is a lightweight embankment method that enables load reduction on soft ground, alleviation of soil pressure behind bridge abutments, and filling in locations where conventional soil construction is difficult. Due to its lightweight nature, when used for embankments or backfilling, it can reduce the load and soil pressure on the ground and structures. Additionally, its good fluidity and the fact that no compaction is required make it suitable for backfilling in narrow spaces and for filling various voids. 【Features】 - Easy to retain due to its lightweight - Fluidity allows for easy construction - Freedom in setting strength and weight - Excellent durability - Easy to remove - Utilizes construction by-products *For more details, please refer to the catalog or feel free to contact us.

The Power Blender Method is a ground improvement technique characterized by the vertical mechanical mixing of in-situ soil and improvement materials, continuously creating a stable improved body. The Power Blender Method includes a slurry injection method, where improvement materials such as cement or cement-based solidifying agents are mixed into a slurry and injected into the ground to forcibly mix with the in-situ soil; a surface application method, where improvement materials are spread on the surface and mixed with a power blender; and a surface application method with a dust collection device, where improvement materials are pumped from a tanker truck, simultaneously collecting dust and measuring before being spread on the surface and mixed with a power blender. NETIS Registration No. CB-980012-V Power Blender Method (Slurry Injection Method). Construction Technology Examination Certification (Certification No. 21) by the National Institute for Land and Infrastructure Management.

The "Ascolam Method" is a technique that involves adding a slurry-type cement-based solidifying agent to in-situ soil while mixing and stirring the soil and solidifying agent using a stirring mechanism that rotates both clockwise and counterclockwise. After penetrating to a specified depth, the rod is withdrawn while continuing to stir, thereby forming a homogeneous soil-cement column underground. Due to its excellent features, this method can be applied to a wide range of uses, including the improvement of soft ground, foundations, earth retention, and the construction of impermeable walls. 【Features】 ■ Stirring mechanism with clockwise and counterclockwise rotation ■ Elimination of the co-rotation phenomenon of soil clumps ■ Minimal variability in improvement ■ Applicable to a wide range of soil types ■ High verticality achieved ■ Low noise and low vibration *For more details, please refer to the catalog or feel free to contact us.

The "RAS Column Method" is classified as a mechanical mixing method for deep mixing treatment, which improves the ground by forcibly mixing the original soil with cement milk using mixing blades. The drilling and mixing mechanism features a double-tube structure where the inner and outer shafts rotate in opposite directions. The inner shaft has specialized blades for drilling hard ground with high torque, while the outer shaft has blades specifically for mixing. Utilizing the effects of the forward and reverse rotation of this mechanism ensures the production of high-quality and homogeneous improved material. 【Features】 ■ Improvement diameter of up to 2,500mm is possible with a high-output auger ■ Capable of penetrating hard ground ■ The issue of cohesive soil rotating together, which has been a problem in the past, is resolved by the forward and reverse rotation ■ The rigidity of the rods is high, and the mutual forward and reverse rotation in the double-tube structure improves drilling vertical accuracy ■ The construction management system allows for real-time monitoring of the construction status *For more details, please refer to the catalog or feel free to contact us.

This is a mechanical mixing deep mixing method that constructs columnar ground improvement bodies by excavating and mixing the ground while discharging slurry of solidifying materials such as cement. By equipping the tip of the auger head with stationary wings and two pairs of mixing wings either above or below, it prevents the co-rotation phenomenon of the solidifying materials and the ground soil, allowing for the construction of improved bodies with stable quality. Due to its lightweight equipment mechanism, it can be selected from small to large construction machines, accommodating a wide range of site conditions. 【Features】 ■ Formation of stable columnar bodies in the ground ■ Elimination of the co-rotation phenomenon of mixed soil ■ Selection of models according to working conditions ■ Obtained "Building Technical Performance Certification" *For details, please request materials or view the PDF data from the download.

The newly introduced Air Pack method is a revolutionary technique that has improved "water-sensitive air mortar" into "water-resistant air mortar." Air mortar and air milk had the weakness of separating air and solid particles when in contact with water, but the Air Pack method addresses this weakness. It allows for limited injection to maintain a plastic solid state instantly, and since there is no material separation, uniform strength can be achieved. This method is suitable for backfilling injections in conditions of spring water, stagnant water, and flowing water, as well as for filling cavities in areas that come into contact with water.
