Technical Development of Cemented Sand and Gravel (C. S. G.) Method for the purpose of Aggregate Recycle

Abstract

In the 21 century the Resource Exhaustion and the Industrial Wastes will become intensified. This report, to be based on the thus society circumstances, relates Technical Development of Cemented Sand and Gravel (C. S. G.) Method for the purpose of Aggregate Recycle.
C. S. G. Method is the Construction Technique to mix up the field material as the riverbed sand and gravel with cement. Generally speaking, Quality Control about Water Content and Grading of C. S. G. Method was not sufficient, and so the fluctuations coefficient of the Compressive Strength wasbig.(the fluctuations coefficient more than 30%)
However, this technique utilizes crushed stone in the process of aggregate manufacturing, and Dust (2.5-0mm), that was always exhausted, and other two aggregates (80-40mm, 40-0mm) are mixed up. This C. S. G. Method executed various Aggregate Tests, and Mixing Tests, verified the Mixing Tests such as RCD Concrete, and manufactured various material as ‘Blend Ratio’.
After all, this quality control enabled to minimize the fluctuations coefficient of the Compressive Strength (the fluctuations coefficient less than 25%).
