Abstract
Development of newer concrete is the need of the hour to meet out today’s demand due to fast growing construction activities. Taller constructions with lesser space involve closer reinforcements lead to suffer the reach of concrete uniformly. Hence concrete with higher degree of flowability without compromising strength comes to the mind of constructor. Such concrete called self-consolidating or compacting concrete and is capable of compacting on its own with no external effort. This paper deals with load deflection performance of such concrete using mineral and chemical admixtures, so that good amount of cement will be minimized without compromising strength and workability. Detailed experimental investigations were done with industrial wastes as replacers to conventional binder (cement) in ternary form. Experimental results of ternary SCC was compared with the results of conventionally vibrated concrete (CVC). Finite element model was developed using ANSYS and was validated with experimental results. It was inferred that ternary SCC beams exhibited more ductile nature compared to CVC beams.

Abstract
This work presents the behavior of a polymer matrix reinforced with h-Boron Nitride (h-BN in powder form) at Nano level reinforcements, to study the strength and thermal stability aspects for high-temperature applications. Composite specimens were prepared by adding varying amount (0.1 to 0.5 wt. percentages) of reinforcements (h-BN) in the base polymer matrix (epoxy). Dispersion of h-BN was carried out using ultrasonic energy. Prepared epoxy beams were tested under tensile load and flexureto evaluate their mechanical properties such as tensile strength and load-deflection conditions. Composite material was tested using Thermo Gravimetric Analysis to study their degradation with increasing temperature. These results were compared with the plain epoxy polymer specimens. This work further investigates the ideal percentage of h-BN that gives the best results in terms of both enhanced properties and economic viability. Scanning electron microscopic testing was conducted to examine the interfacial surface adhesion between the h-BNs and the polymer matrix. Polymer composite with h-BNs 0.4% by weight showed enhanced results in strength by 49.25% when compared with plain epoxy beams due to uniform filler dispersion. It was found that addition of h-BN Nanoparticles, the material loss in the elevated temperatures has been reduced.

Abstract
Currently, all nations have taken major initiatives in developing the infrastructures such as express highways, power projects, industrial structures, multi-storeyed residential flats etc., to meet the requirements of globalization. Concrete plays a key role and a large quantum of concrete is being utilized in every construction project. The use of such huge quantity of concrete will lead to several environmental impacts as well as economical issues. To reduce the environmental impact, the important thing is to diminish the use of the natural constituents of the concrete by effectively utilizing the abundantly available industrial by-products. And to reduce the economy, the major initiative is to minimize the quantity of cement and aggreagates in concrete by partial substitution with suitable by-products and using lightweight technology. Hence this study is oriented towards designing a new mix for the production of foamed concrete, thereby producing a sustainable and greener concrete. Application of green concrete is an effective way to reduce environmental pollution and improve durability of concrete under severe conditions. Foamed concrete using quarry dust replacing the manufactured sand partially and with fly ash and GGBFS replacing cement partially is dealt in detail in this paper. It is observed that there is considerable increase in compressive strength with addition of quarry dust, fly ash and GGBFS.
