Ace Sand Method - High Strength Cement-Based

Aiming for further improvement in the reliability of construction quality! The use of high-strength cement-based backfill materials is increasing.

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.
