Examining the Mixing Plan and the Results of the Plastic Concrete

In order to control seepage from the dam, various methods are used to reduce water seepage. One of the methods of reducing the permeability of the water according to its material is the formation of cut-off walls and filling them with plastic concrete materials. In this study, it has been tried to study the mixing plan of the plastic concrete of the main body of the cut-off wall of the Nargesi dam and to determine the relationships between results of different ages of compressive strength and elasticity modulus of 108 panels of cut-off wall in this project. The results indicate that the growth rate of elastic modulus in a period of time is less than the growth rate of the compressive strength, and in other words, the plasticity of the concrete is changed less over time. The results also show that the passage of time has a great influence on the compressive strength and modulus of elasticity and the passage of time, which is very effective in designing cutoff wall, significantly increases the compressive strength and modulus of elasticity. The relationship between the time parameter and the compressive strength is discussed in the present article.
