Abstract

The purpose of the study is to optimize the mix design of an eco-friendly concrete using Taguchi’s approach. The experiment was designed using the Orthogonal Array technique. A total of 36 cubes of size 100 X 100 X 100 mm were cast in order to determine their physical and mechanical properties. Optimum mix was selected, followed by confirmation trial. The results showed that the compressive strength of the concrete decreased as the percentage of the coconut shells increased.


Description

The major forces responsible for economic and social transformation in society are: population growth, industrialization and urbanization, globalization of market economy and consumerism and environmental pollution (Mehta, 2010). The unprecedented demographic, social, technological and environmental changes in the world have had a great impact on all industries, including the construction industry. Concrete industry is facing an additional challenge of building concrete structures that are environmentally more sustainable (Mehta, 2001). Future demands for clean water, clean air, waste disposal, safe and rapid transport of people and goods, residential and industrial buildings and sources of energy are going to increase due to growing population, industrialization, urbanization and globalization. Concrete industry today is the largest consumer of natural resources, such as water, sand, gravel and crushed rock. Being the most important player in infrastructure development and a major consumer of energy and natural resources, the concrete industry needs to be reoriented through the adoption of environment-friendly and more sustainable technology (Bjork, 1999).
