... Geosynthetics Clay Fiber reinforcement Cement Fly ash The use of admixture materials such as cement and lime is a long-established method for improving the geotechnical characteristics of clay soils. Recently, fly ash, which is a waste product of thermal power plants, has been added to cement...

...A.R. Estabragh; P. Namdar; A.A. Javadi ABSTRACT: A series of experiments were carried out to investigate the behavior of cement-stabilized fiber-reinforced clay with different cement and fiber contents. Three groups of tests were conducted, on: (1) reinforced samples with four different fiber...

...Y. Yilmaz ABSTRACT: This paper describes the findings of a series of laboratory unconfined compression tests and split tensile tests performed on specimens of varying fiber–sand–clay proportions. Sand was mixed with clay at six different proportions, namely 0.0, 1.0, 2.5, 5.0, 7.5, and 10.0% by dry...

... of the fiber. The lower aspect ratio (L/d) appeared to have a greater effect in reducing the swelling pressure for the two types of fibers. The impact of mixing the fibers with the clayey soils increased as the clay fraction increased. Table 1. Physical properties of the soils used...
