In cases where the influence of buoyancy is a concern and you want to make it heavier than water, use air mortar with reduced air bubble introduction and mixed sand. If you can secure a plant yard and want to construct a large amount of air mortar, we recommend the "on-site mixing method," which is also economically advantageous. Additionally, in extremely small-scale situations of less than 1m3, or when the ready-mixed mortar plant supplying fresh mortar is far away, resulting in particularly poor transportation efficiency, the "on-site mixing method" can also be effective in terms of construction efficiency and cost-effectiveness. 【Features】 ■ Strength and weight can be freely designed ■ Plant yard can be secured ■ Economically advantageous when constructing a large amount of air mortar ■ Effective in cases of particularly poor transportation efficiency *For more details, please refer to the PDF materials or feel free to contact us.

The "Ace Sand Method" is a construction technique that utilizes locally generated soil (especially sandy soil), river sand, recycled sand, and improved soil, adding a solidifying agent and water to fluidize it, and then pumping it to areas where backfilling is difficult. At that time, pumping sand with a concrete pump was revolutionary, as it made backfilling in narrow spaces easy, ensured sufficient water tightness, and contributed to shortening construction periods, attracting significant attention. To prevent material separation underwater, water-resistant agents and bentonite were mixed to enable underwater placement. *For more details, please refer to the PDF materials or feel free to contact us.*

• Civil Engineering Method

The "Ace Sand Method" was realized and started in 1986 with the idea that "bubbles can be used to pump mountain sand." The pumping of mountain sand, which is prone to material separation, was made possible by continuously mixing while pumping. Additionally, it utilizes locally generated soil (especially sandy soil), mountain sand, recycled sand, and improved soil, mixing them with solidifying agents, water, and bentonite to ensure the required permeability performance, and is also used as filling mortar for impermeable walls through methods such as the CD method. *For more details, please refer to the PDF materials or feel free to contact us.

In recent years, in addition to the general flowable backfill with low mixing ratios, there has been an increase in the use of high-strength cement-based backfill materials that do not require compaction and possess fluidity for backfilling around buildings where high seismic resistance is required. For improved ground using high-strength cement-based backfill materials, it may be necessary to determine the shear wave velocity (Vs) value. In preliminary mixing tests, determining the Vs value in addition to the uniaxial compressive strength is not only helpful for deciding the mix but also allows for the estimation of the Vs value through the uniaxial compressive strength, which is conducted as part of daily quality control during actual construction. There has also been an increase in the construction achievements of high-strength cement-based backfill materials using the "Ace Sand Method," and we aim to further enhance the reliability of construction quality in the future. *For more details, please refer to the PDF document or feel free to contact us.

In some regions, it can be difficult to procure mountain sand, and as an alternative, we have been promoting the reuse of industrial by-products such as recycled sand and improved soil. However, with the increasing need for recycling being pointed out, there has been a growing demand to reuse excavated soil due to the large scale of construction projects. Therefore, while maintaining a "simple & compact" continuous mixing system that excels in construction capability, we have made various improvements to efficiently remove metals such as bolts, nuts, and wires, which are often mixed in the excavated soil, as well as rocks over 40mm. Moving forward, we will continue to promote the recycling of industrial by-products such as crushed stone powder, coal ash, and improved soil, as well as further advance the recycling of excavated soil. *For more details, please refer to the PDF document or feel free to contact us.*

Initially, the "Ace Sand Method" involved continuously mixing and pumping mountain sand, water, and air bubbles. However, depending on the soil type and the backfill locations, it sometimes took several days for compaction. To ensure that the method could be used without regard to soil type or backfill location and to make it walkable by the next day, it became common to mix in a small amount of cement. For the soil used, when the generated soil requires pre-treatment or when the plant yard is narrow and the quantity is relatively small, purchasing materials such as mountain sand, recycled sand, or improved soil allows for easy fluidized backfilling. By adhering to the principle of "keeping it simple and compact," the plant makes it easier to transport construction machinery and streamline assembly and disassembly, while also facilitating the securing of the plant yard. *For more details, please refer to the PDF materials or feel free to contact us.*

• Civil Engineering Method

The "Ace Sand Method" began with the idea of discarding the fixed notion that sand cannot be pumped with a pump truck and thinking that it might be possible by "effectively utilizing air bubbles." To achieve a walkable state in a relatively short period after sand pumping, it is necessary to select sand with an appropriate fine particle content (silt and clay). Additionally, since no cement is used, planting is possible by combining with imported soil and other materials. The plant is compact, requires fewer pieces of equipment for transport, and can be assembled and disassembled using a mobile crane truck that has been brought in, making it a very simple and compact plant. *For more details, please refer to the PDF materials or feel free to contact us.
