 Abstract

Concrete is till now most fashionable material in construction industries and one of the most environmentally harmful materials. Due to environmental concerns of cement industry, there arises a strong need to make use of alternate technology which is sustainable. Geopolymer is an alternative material which can act as a binder by replacing cement. In this experimental work have analysis the strength and durability properties of fly ash and ground granulated blast furnace slag (GGBS) based geopolymer concrete and also the cost comparison with the normal concrete. The concentration of sodium hydroxide is 13 molarity(M) solutions kept a constant to prepare the mix and alkaline liquid to binder ratio as 0.40, but changing ratio of sodium hydroxide (NaOH)to Sodium silicate (Na2Sio3) 1.50, 2.00 and 2.50. The cube compressive strength was calculated for different alkaline activator solution for different mix Id. i.e. F100G0, F90G10, F80G20, F70G30 and F60G40, (Where F and G are, respectively, Fly Ash and GGBS and the numerical value indicates the percentage of replacement of fly ash by GGBS). The cube specimens are taken of size 100 mm x 100 mm x 100 mm. ambient curing of concrete at room temperature was adopted. In total 45 cubes were cast for different mix Id and the cube specimens are tested for their compressive strength at age of 7 and 28 days respectively. The strength of geopolymer concrete was increased with increase in percentage of GGBS in a mix. It was observed that the mix Id F60G40 gave maximum compressive strength of 66 MPa was observed for ratio of NaOH to Na2Sio3 2.50. Thus the geopolymer concrete have a relatively higher strength and better durability.

 Abstract

Hybrid composite materials consisting of alternatively laminated layers of glass fiber and carbon fibers in an epoxy resin, have been studied. The alternate layers of fibers are bonded together with epoxy resin by hand layup process and cured by electric oven to form hybrid composites. The tensile and flexural behavior of hybrid composites was investigated in accordance with ASTM standards. The results obtained indicate that tensile Strength and flexural strength of carbon laminate is increased than glass fiber laminate and vary nearer to the hybrid fiber laminates. The mechanical properties of hybrid (glass + carbon) fiber laminates is close to carbon fiber laminate. The obtained results causes to replace the carbon fiber by hybrid fiber laminate and can reduce the material cost by at least 40-45%.

 Abstract

Different metals are used with different geometrical cutouts in different industrial products; like aerospace, automobile, etc. this metallic components undergoes cyclic loading of (fatigue) condition from so many years. A lot of research work has carried out for the solution of fatigue. In this project work, we will try to identify the different parameters affectinginfluencing the operational parameters, which directly or indirectly affect fatigue. In this work, our objective is to find out the Fatigue Crack Growth (FCG) on IS 2062 Grade A (E-250) plate. Fatigue Crack-Growth of plate had performed on Servo Hydraulic Machine. In this study, to find the fatigue crack growth of plate constant amplitude load is used. There is mainly two modes first opening or tensile mode and second in plane shear and mixed of these two modes were experimented for fatigue crack growth-rate. In addition, FE analysis has done for study of fatigue crack-growth propagation.

 Abstract

When any data is stored in a private cloud it is visible and under access to all the internal members of the organization this may create threat to the organization by the internal hackers. So, our project provides a way of making the data visible only to members in a group who satisfy some credential measure. And makes the data hidden to others thus enhancing security and avoiding data theft. A dynamic grouping algorithm which gives good performance is obtained to group the data immediately once it is uploaded in Cloud. Data stored in a private or hybrid cloud of any organization remains secure from the internal hackers, thus by making it visible only to employees who satisfy the credentials. It also helps in secure data transmission in a group that has some internal hacker, by identifying them in that possible group.
