Abstract
In order to comply with the implementation of sustainable development, the construction industry through the use of less polluting green energy technology is already imminent and more had to do. Production of Portland cement consumes large amount of energy and releases lots of carbon dioxide, nevertheless, the developing of sustainable society means more urgent and important to search for new cementitious materials to replace Portland cement in future constructions. The research employs Taguchi method to identify the key factors influencing the performance of alkali activated silica fume concrete in which amorphous silicon solar cells are ground and added into the mixture. Taguchi method has made valuable contributions to statistics and engineering. It provides techniques for investigating variation in experiments, system, parameter and tolerance design, all of which have been influential in improving manufactured quality. The conclusions were made thru ANOVA and F-test based on the statistical analyses. Next, we expect the inconsistence observed in the study to be further resolved by Grey Relational Analysis which is a normalization evaluation technique to solve the complicated multi-performance characteristics optimization effectively.
Highlights
Due to environmental and chemical factors, concrete structures undergo a number of degradation processes during their life cycles [1,2,3]
The objective of this paper is to identify the key factors influencing the performance of alkali activated silica fume concrete in which amorphous silicon solar cells are ground and added into the mixture the properties of alkali-activated materials in solar PV cells
In previous studies [5,6,7,8], we had demonstrated the study results of general quality of concrete blended with waste solar PV cells
Summary
Due to environmental and chemical factors, concrete structures undergo a number of degradation processes during their life cycles [1,2,3]. How to reduce the degradation of concrete has become a key issue to ensure concrete quality. The objective of this paper is to identify the key factors influencing the performance of alkali activated silica fume concrete in which amorphous silicon solar cells are ground and added into the mixture the properties of alkali-activated materials in solar PV cells. The use of ground solar cells on the mechanical properties and durability of concrete has been investigated. This research attempts further to identify the key factors influencing the quality of alkali activated concrete containing the ground amorphous silicon solar cells. Utilization of Taguchi method is to minimize the experiment number using standard orthogonal array and Signal to Noise ratio (S/N)
