Abstract
In this study, mix proportion parameters of high strength concrete (HSC) were analyzed by using the Taguchi’s experiment design methodology for optimal design. For that purpose, mixtures are designed in a L27 orthogonal array with six factors, namely, ‘Silica Fume’, ‘Steel Fiber’, ‘Super-Plasticizer’, ‘Maximum Aggregate Size (AG)’, ‘Water / cementitious material (W/C) ratio’, ‘Fly Ash’. The mixtures were extensively tested to meet technical requirements of HSC. The experimental results were analyzed by using the Taguchi experimental design methodology. The best possible levels for mix proportions were determined for maximization of compressive strength at 7, 28, 56, 90 days, splitting tensile strength at 28 days, flexural strength at 28 days, and the slump. Also the best possible levels for mix proportions were determined for minimization of the production cost. It was found that steel fibers and fly ash are the most dominant factors in the process of optimization. The advantage of using steel fiber and fly ash was the reduced energy and cost associated with the raw materials which meant more sustainable concrete could be attained. It was also found that there is a necessity to apply a multi- response optimization to get the best mix proportions.
Highlights
A lam et al, [1] in their research illustrated that the countries need to create a healthy and sustainable economy to achieve sustainable development (SD)
In order to determine the effects of various factors, which are affecting the results of experiments, different methods and approaches are used
In the traditional approach, which is known as full factorial design, the experiments are performed for each condition, which consists of all factors
Summary
A lam et al, [1] in their research illustrated that the countries need to create a healthy and sustainable economy to achieve sustainable development (SD). Several evaluation methods have been proposed in responses to these challenges, but the lack of a complete framework for sustainable concrete material remains Because of these issues, the strategy of this research is to reduce the level consumption of resources to utilize it for present and future needs. Khiabani et al [11], presented the results of the effect of high temperatures on the retained mechanical properties of High Strength Concrete (HSC) using Taguchi method They found that the water to binder ratio is the most important factor in mix proportion in both compressive and tensile strength. Hinislioglu et al [16] optimized the early flexural strength of concrete pavement (CP) by using the Taguchi Method They found the optimum conditions to be 0.35 water / cementitious ratio, gradation with minimum content of fine aggregates, 5% Fly ash content, and 0% silica fume content at 7 days curing. Mix proportions were set to their best possible levels for the minimization of production cost
