Geopolymer Concrete: An Experimental Investigation of Workability and Compressive Strength of Geopolymer Concrete with PPC

The Romans constructed the Colosseum from a primitive form of concrete. It was made by using concrete using lime, which was burned to create quicklime, water and volcanic ash. The volcanic ash served as the aggregate and is likely the reason Roman concrete, which was 10 times weaker than the concrete used presently, but it lived even after almost 2,000 years. Moreover Pyramids were possibly made of this long lasting material the Pyramids are still in good shape, which demonstrates the excellent durability of geopolymer. This era have witnessed a lot more varieties of construction and concrete. This paper is an exploration of “Geopolymer Concrete” which offers the “greenery” construction as well as to reduce the air pollution and consumption of Cement. The Ordinary Portland Cement (OPC) is most widely used construction material, approximately for every tone of cement production 1 tone of CO2 emitted by cement factory. The Cement production is responsible for approximately 5% emission of Co2 of world. Geopolymer Concrete results from high silica rich material. A research undertaken included study of Geopolymer Concrete mix design, Workability, Compressive and Tensile strength of concrete. A low calcium fly Ash was used with both Sodium silicate solution and Sodium hydroxide solution in mix. Sodium hydroxide solution with 5M, 8 M, 10 M and 12 M concentration, Sodium silicate to sodium hydroxide ratio is 2.0 was used .The ratio of Alkaline liquid to fly ash 0.49, heat curing was adopted at 60 + 5°C for 24 h and room temperature curing at 23 + 2°C.

Image Processing For Haze Removal

This paper focuses on implementing image processing for human understanding in low visibility using different image processing technologies, high-speed processors, employing the BBB board in designing embedded systems and protocols with their comparative study. We have proposed a system called as “image processing for human understanding in low visibility”. The purpose of this application is to overcome the problem of Low-visibility conditions for Navigation of vehicles. Driving at night, in blizzards, in sand storms, or in fog form an obvious set of challenging conditions. The main aim is to solve the problem of low visibility by advanced image processing technique purpose to improve the perceptual quality of images that lack the contrast or color depth perceived by the human visual system. This paper provides the use of high-speed infrared cameras and advanced image processing techniques to deal with the problem of low visibility.

Multi Spindle Drilling SPM for G91 Engine Hood

The use of SPM increases productivity and maintain the accuracy of drilling operation for a number of times. This paper gives literature survey about multi-spindle drilling machine and focuses on previous development in Multi-spindle drilling machines. Multi-spindle head machines are used in mechanical industry to increase the productivity of machining systems. The multi-spindle drilling machines are production type of machine. It is used to drill two holes in a workpiece simultaneously in one setting. The holes are drilled on a number of workpieces with the same accuracy to make them interchangeable. The overall use of drilling SPM increases productivity rate largely as compared to a use of conventional drilling machines.

Design and Fabrication of Pipe Bending and Pipe Rolling Machine

This paper presents the design and fabrication of combined pipe bending and pipe rolling machine. There is no single machine made to perform both rolling and bending operations. Hence we have selected this project to design and fabricate combined bending and rolling of pipe using single power source. The defects occur during bending are too much tedious to eliminate. While designing the machine we tried to minimize defects and minimize the initial cost of the machine. Using this machine both bending and rolling of pipe of outer diameter 19 mm and thickness 1-2 mm is possible with single power source only.

Design and Development Waste Heat Recovery from Domestic Refrigerator

In today’s world the tremendous requirement of energy in needed in every sector like automobile, civil, power plant etc. in the view of this point, we need to recover the waste heat for various applications. This type of heat recovery will ultimately increase the productivity and efficiency of factories. This waste heat can reuse as input by various methods, out of this we take the case study of the domestic refrigerator. There is an economic reason to extend the useful life of the landfill because once the old landfill is filled, the new one can be found only at the greater distance, and this increases remarkably the transportation cost. Therefore, waste has to be recovered as much as possible. To do this, in developing countries context, small-scale composting promotion is widely accepted and the contribution of informal recycling is also widely recognized. The question remains to what extent composting and informal recycling contributes to the waste diversion. To create a platform for discussion and learning, a model is established. The model in this paper is based on the system dynamics (SD) approach. The simulation results with the data collected in Phnom Penh city, Cambodia, show that waste recovery through small-scale composting and informal recycling cannot contribute significantly to the waste diversion without other supporting policies.

Bioprospecting of Neem and Hibiscus against Corrosion Caused By Soil Microbes on Zinc and Its Alloys Buried In Soil

This study concerns with the role of corrosion product deposition in microbial corrosion between zinc and its alloys buried in the soil and soil microbes such as S.aureus, Streptococcus, B. subtitles, Lactobacillus, Proteus, Corynebacterium, Pseudomonas, A.niger, Mucor and Desulphovibro sp and also about inhibition by using plant extracts of Neem and Hibiscus which have phytochemicals like flavonoids and alkaloids that detecting by using techniques such as weight loss and thermodynamic studies. Langmuir and Freundlich, Temkin and Florry-Huggins models are employed to analysis adsorption occurred in the experimental data of adsorption isotherms. The Freundlich, Langmuir and Temkin models are employed to analysis adsorption occurred in the experiment.
