“…In the field of design of experiments and optimizing the manufacturing processes, published research studies related to the optimization of a single performance characteristic by Taguchi approach (Ross, 1996;Lin, 2004;Ghazy, 2012;Ramezanianpour et al, 2014;Rivera et al, 2014;Ghazy et al, 2015;Kaushik, 2017;Abd Elaty et al, 2017;Uysal et al, 2018).…”

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 of experiments as well as to analysis the results. Recycled concrete aggregates (RCA), marble powder (MP) and limestone powder (LP) were considered as the main variables (control factors) to develop the sustainable geopolymeric concrete designated for building bricks. Four responses where density, mechanical properties (compressive and flexural strengths) at 28 days age and the percentage of water absorption were conducted. The test results revealed that combining an eminently RAC, MP and LP can produce GB with 28 days compressive strength of about 36-58 MPa with ambient temperature. The RCA was the most influential factors on the performance of GB due to its performance contribution. Furthermore, the GB containing RCA is suitable for environment friendly construction and is comparable to a normal GB made with natural aggregate.

“…By minimizing the usage of cement content in making of SCC, we can save our environment from green house effect since in the production of cement 87% of CO2is emitted, further by reducing cement we preserve from high desolation of natural resources like CaCO3 etc. Therefore there is a need to economize the use of cement with supplementary cementitious materials (Uysal, 2019;Shetty, 2008).…”

This paper investigates the effect of sisal fiber addition on fresh ,mechanical properties of self compacting concrete(SCC) and flexural performance of fiber reinforced RC beams made with mineral admixtures like Meta Kaolin (MK) and Fly Ash (FA)which is an industrial waste. The mixes were prepared by varying MK content from 5% to 15% with 5% increment with constant fly ash content of 30%. The results reveal that increasing the content of MK beyond 10% leads to reduction in strength. And also the negative influence of MK and fiber addition on workability performance was overcome by the addition of FA, super plasticizer and viscosity modifying agent (VMA). Based on the test results it is evidenced that FA and MK make use of mineral admixture in the production of SCC. It also clarifies that the addition of sisal fiber improves mechanical properties of concrete. The research work shows that the ultimate load of fiber reinforced RC beams was raised when compared to normal RC beams. The flexural toughness and ductility of concrete was found to increase appreciably when sisal fiber was added.

This paper presents results of an experimental study of a residue of masonry (RM), sampled from a construction and demolition waste (CDW), added as a supplementary cementitious material (SCM) to partially replace up to 50% of Portland cement in the preparation of mortars. The pozzolanic activity (fixed lime and strength activity index), setting time, heat of hydration, the (autogenous and drying) shrinkage and compressive strength tests were carried out. The results show how the RM has a positive activity because the increase of RM replacement level in the mortars generates a lower heat of hydration and autogenous and drying shrinkage. The fixed lime at 28 and 180 days, indicating that the RM exhibits in some degree pozzolanic activity and the Strength Activity Index (SAI) was 77.13% and 84.36% of the compressive strength of 100% OPC mortar at the 7 and 28 days respectively, which conformed to ASTM C311. These results indicate that RM should be considered appropriated for using as a supplementary cementitious material.
