Optimization of recycled concrete aggregate geopolymer bricks by Taguchi Method

Abstract The experimental program was undertaken to investigate the performance of different geopolymer bricks (GB) made with different amounts of industrial waste materials by Taguchi method. Taguchi approach (with L16 orthogonal array) was used to design the experimental plan to reduce the number...
