Strength and Density of Soil-Cement Concrete Manufactured by Taking into Account of the Concept of Apparent Saturated Surface-Dry Condition of Soil

Abstract

sturated surface-dry condition of aggregates can be estimated by the Japan Industrial Standard for the manufacturing of mortar and concrete. However in soil-cement concrete using cohesive soil in addition to sand and cement, the control of moisture content of soil is very difficult thereby no attention has focused on the saturated surface-dry condition of soil.
The authors have defined the concept of apparent saturated surface-dry condition of soil in the previous papers and proposed four evaluation methods¹⁾, ²⁾. In this paper, experimental results of strength and density of concrete with cohesive soil-sand-cement system using a new concept of effective water of soils are presented, and a mixture design principle for the soil-cement concrete using cohesive soil and sand is described.
