Authors: Manjunath R , Narasimhan Mattur C 
Published: November 2019

Abstract
A new class of High–Strength Flow ableAlkali activated Slag Concrete(HSFASC)mixes is developed using steel slag sand and EAF (Electric Arc Furnace) slag aggregates, respectively, as the fine and coarse aggregates. These mixes use the ground granulated blast furnace slag as the source material. Thus it is to be recognized that all the three materials used – GGBFS, slag sand and EAF slag aggregates are by-products of the Iron and Steel Industry, and are available in very large quantities demanding safe disposal. Different amounts of Sodium silicate solutions, with specified amounts of Sodium Hydroxide flakes dissolved in them, are used as alkaline solutions. Test specimens were cast using a total of nine HSFASC mixes, (based on Taguchi’s Method), each of which satisfied the relevant EFNARC guidelines with respect to their rheological properties. The test results indicate higher compressive strengths values for all the mixes tested herein. Microstructure studies are conducted on samples from the fractured surfaces of test specimens of different mixes, using advanced SEM, EDX and XRD analyses and the results are discussed.

Published: November 2019

Abstract
This paper deals with the experimental investigation on the mechanical, thermal and moisture properties of Ground Granular Blast Furnace Slag (GGBS) based Geopolymer Pervious Concrete (GGPC) with different size of aggregates. The concentration of NaOH is maintained as 12 M throughout the study. Fine aggregate is completely eliminated in the mix proportion to maintain the pervious nature. Coarse aggregate size is varied in three sizes such as 6mm, 12mm, and 20mm to study the effect of aggregate on the properties of GGPC. The ratio between sodium silicate and sodium hydroxide is maintained as 2.5 throughout the study, and the liquid to solid ratio is maintained as 0.45. The results from the experiments revealed that the compressive strength is higher for the aggregate size 12 mm at the end of 28 days compared to other mixes. The Co-efficient of Permeability (k) is increased with respect to the increase in the aggregate size from 6 to 20 mm.

Published: November 2019

Abstract
In this paper, an attempt has been made to develop Fly ash based self- compacting geopolymer concrete mixes with varying volume of pastes using conventionally available river sand as fine aggregate and crushed granite chips as coarse aggregate. These mixes were developed usingFly ash as the only major source material in the production of SCC mixes. Different amounts of Sodium silicate solutions, with specified amounts of Sodium Hydroxide flakes dissolved in them, are used as alkaline solutions. The total of four mixes were developed with varying volume of pastes in the range of 0.40 – 0.52 (within an interval of 0.04). These mixes were evaluated for their flow ability characteristics as per the relevant EFNARC guidelines. Further the mixes were evaluated for their mechanical properties in terms of compressive strength, splitting tensile strength and water absorption characteristics. Durability tests by means of subjecting to acidic and sulphate environments, along with their resistances to sustained elevated temperatures for a sustained period of 2 hours upto 800º C were carried out for all these mixes. The test results indicate better flow ability characteristics, along with their mechanical and durability properties.

Published: November 2019

Abstract
Use of Fibre Reinforced Concrete (FRC) is one of the ways of overcoming the low tensile strength of concrete. Both organic and inorganic fibers can be made use in the production of FRC. On the other hand, the use of waste plastic is causing a serious environmental pollution since the plastic don’t deteriorate. Such waste plastic can be reused in the form of fibres to produce waste plastic FRC. Further, flyash, microsilica and redmud are another industrial waste materials adding to environmental pollution. These waste materials are having cementatious properties and can be used along with waste plastic fibres in concrete to reduce their detrimental effect on mother earth. Therefore in this paper an attempt is made to assess the suitability of waste plastic FRC for construction purposes when different percentages of flyash, microsilica and redmud are introduced. Various strength properties such as Compression, Tension, Flexure and Impact are studied along with workability characteristics. Based on the obtained results the industrial wastes such as flyash, microsilica, redmud and also waste plastic fibres can be used in the production waste plastic fibre reinforced concrete composite material.

Abstract
Owing to the fact of continuous discharges in RC circuit based μ-EDM process, it is indeed very difficult to analyse difficult-to-control single discharge pulse. This work is thus aimed to develop an innovative technique for generating single discharge in the process. An electrical circuit, parallel to the existing discharge circuit of μ-EDM, has been integrated in-house for the purpose and verified for its applicability over a wide range of metal alloys. For example, single crater diameters of approximately 7μm, 10μm and 18μm have been achieved for stainless steel, Inconel and brass respectively at minimum energy input. The single discharge generatorhas been developed expecting it would be helpful in gathering information such as volume removal by each discharge which will definitely lead to development of a robust thermal model for material removal in μ-EDM.

Abstract
The cost involved in certain additive manufacturing processes is comparatively higher than traditional manufacturing. When the cost of additive manufacturing process is optimized, it will enable manufacturers to deploy the technology as an alternative for traditional manufacturing. Product life cycle analysis gives better understanding about the cost drivers in additive manufacturing. A better understanding of the cost drivers in additive manufacturing tends to optimize the parameters involved in the process. The difference in cost drivers can be compared before and after the implementation of cost optimization techniques by comparing the variation of cost drivers between standard and optimized production. In this study the cost drivers associated with additive manufacturing are analysed and optimized.

Published: November 2019

Abstract
The major challenge in the recent construction sector is to design the building with the cost effective manner. In order to address this issue, self weight of the structural member has to be reduced considerably, and then simultaneously the dimensions will be minimized. This will be only by means of introducing light weight concrete (LWC). Different light weight aggregates are used by the past researches to reduce the density. This study is planned to achieve the properties of LWC in considering the importance to enhance the strength factors. Hence, in this experimental investigation, the influence of the silica and pumice stone is studied on the various partial and full replacement levels. The specimens are casted based on the arrived mix proportion and tested against compression, split tension and flexure. The test result shows 0.6 to 0.7 times the strength achieved of the conventional concrete for this developed LWC mix proportion. A considerable improvement is seen in the strength parameters by the presence of 5 % silica fume.
