LABORATORY AND FIELD TESTS ON CHARACTERISTICS OF DEFORMATION AND STRENGTH OF AIR FOAMED LIGHTWEIGHT SOIL MIXED WITH SHORT FIBER

Abstract

Although the air foamed lightweight soil method has become popular, it has some problems such as scatter of the strength and its durability. To overcome these problems, we try to mix the short fiber into the air foamed lightweight soil. This paper reports the results of laboratory and field model tests for the air foamed lightweight soil mixed with short fiber. In the laboratory test, we verify the effect of cement content and specific gravity for strength by mixing short fiber. In the field model test, the weight falls to top surface of the air foamed lightweight soil mixed with short fiber. We verify that the impact resistance is improved by mixing short fiber. Additionally, this paper repots the results of ongoing durability test for the air foamed lightweight soil mixed with short fiber.
