The Grey Relational Analysis of Quality Investigation of Concrete Containing Solar PV Cells

Abstract

Abstract. The construction industry through the use of less polluting green energy technology is already imminent and more had to do, and continue to improve as the development of green energy. Concrete is the most common-used construction material in the modern world. Traditional concrete is a composite, which is made of aggregate, Portland cement and water. 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 and Grey Relational Analysis (GRA) to invetigate the performance of alkali activated silica fume concrete in which amorphous silicon solar cells are ground and added into the mixture in three-phase analysis. Firstly, this study used Taguchi's orthogonal array to evaluate the influence of the control factors and identify the important factors influencing quality characteristics. Secondly, all normalizing experiment variables ranked the grey relational grades of multi-quality characteristics. Finally, this study integrated the Taguchi method and the equal weights by using GRA to establish both equal and entropy weight-based grey relational values.

Taguchi- Grey relational analysis for Optimizing the Compressive Strength and Porosity of Metakaolin-Based Geopolymer

“…They were used Taguchi-Grey relational analysis to investigate and optimize the effect of ground granulated blast furnace slag replacement, water to geopolymer solids ratio, molarity of NaOH solution, binder content and Na2SiO3 to NaOH solution ratio on setting time, workability and compressive strength of fly ash-based geopolymer concrete [28]. However, it is well documented that it has been utilized to optimize many other products and processes, these includes literature [29][30][31][32][33].…”

Performance of Green Concrete and Inorganic Coating Materials

“…Further, with time, coatings can age and peel off, thus resulting in the loss of their concrete protection function. This study examined whether the combination of GC, industrial waste, and an inorganic coating material (ICM) can overcome this problem and achieve a sustainable protection function [ 34 , 35 , 36 , 37 , 38 , 39 ]. ICM is inorganic in nature and does not contain any organic chemical materials or solvents.…”
