FLUIDIZATION TREATMENT SOIL FOR BACK-FILLING
To provide fluidization treatment soil for back-filling treatment suitable for a lower side of a terminal part of a building foundation and a site at which water service pipes, gas pipes, and the like are laid in a complicated manner and an adjacent road and parking area exist.SOLUTION: Fluidization treatment soil for back-filling is made by adding 5.8 to 11.5 pts.wt. of cement and 42.8 to 64.5 pts.wt. of water to 100 pts.wt. of sand/soil having grain sizes made to be under 10 mm. A flow value of the fluidization treatment soil is made to be 160 to 450 mm. Strength of uniaxial compression after material age 28 days after hardening is made to be 1.0 to 3.0 N/mm2. As a result, the fluidization treatment soil is made to have flowability to a complicated site and strength high enough to endure vehicle traffic and a property easily collapsible by a backhoe after hardening.SELECTED DRAWING: Figure 1
【課題】 本発明は、ビル土台の末端部の下側や、水道管やガス管等が入り組み且つ道路、駐車場が隣接される場所に好適な埋め戻し処理用の流動化処理土を提供するものである。【解決手段】 埋め戻し用流動化処理土は、１０ｍｍアンダーとした砂／土１００重量部に対し、５．８〜１１．５重量部のセメントと、４２．８〜６４．５重量部の水分を加えて成り、そのフロー値を１６０〜４５０ｍｍとし、硬化後の材齢２８日後の一軸圧縮の強さを１．０〜３．０Ｎ／ｍｍ2としたことを特徴とする。その結果、入り組んだ場所への流動性と、硬化後には車両走行に耐える強度をバックホーでの易崩壊性を備えたものとなる。【選択図】 図１
