The Sabo-CSG Method (provisional name) is a method of constructing structures by mixing cement with unproc-essed bed material obtained near the site. It is executed similarly to the CSG method and INSEM method, but these are methods of improving sand and gravel. With this method, the materials are mixed based on the same concept as concrete.
This report is a detailed explanation of the design of the standard mix proportion and the results of a verification of the method in the field using general purpose construction machinery. The following summarizes the findings.
1) Laboratory experiments show that it is necessary to reduce fluctuations of the quantity of water per unit volume of sabo-CSG material (during the mixing of the materials) in order to obtain the required consistency and compres-sive strength.
2) A consistency with a VC value between 5 and 10 seconds is appropriate for the use of a compact vibrating roller.
3) It is possible to use a simple mixing method employing an agitator-body truck.
4) It is counted on to reduce construction costs to a level lower than that of concrete.
