Study on Clay Core Replacement with Fiber Reinforced Concrete (Polypropylene) Core In the Rock-fill Dams

Bayat Pour, Mohsen LU and Hataf, Nader (2014) 9th International Soil Science Congress on '' The Soul of the Soil and Civilization''
Abstract
This paper is intended to present the results of an experimental investigation upon the possibility of clay core replacement with fiber (polypropylene) reinforced concrete core in rock‐fill dams. Within the rock‐fill dams, usually clayey soil is used as the main core material of the whole structure. Due to the fact that this kind of soil, being used; would have caused many problems such as; a huge amount of clay materials required for the core, more time needed to complete the project, the clay core precise parameters monitoring and control (e.g. humidity), and etc., this paper attempts to present some kind of fiber reinforcement concrete; in order to solve these problems. In order to achieve this; different mix designs are presented;... (More)

In order to achieve this; different mix designs are presented; employing the polypropylene fiber; an optimized form of mix designs in terms of permeability, flexibility, and concrete strengths criteria is obtained. Afterward, a comparison between fiber reinforced polypropylene concrete, and the clay core has been made. In the end, the economic issues and environmental outcomes of the proposed concrete have been determined and explained. (Less)
