This Civil Project On Use Of Fly Ash In Different Countries report gives brief explanation Use of fly ash in different countries. China is the most Ash production and use country. Fly ash, a residue of burning of pulverised coal and lignite in thermal power stations, is now being accepted as a resource material. The concerted efforts in Mission Mode that began in India about decade back, have developed confidence in fly ash utilisation technologies and its large-scale utilisation. Till about a decade back, fly ash had been considered a “Polluting Industrial Waste” and most of it was being dumped in the ash ponds. Very few utilisation areas of fly ash were known and general perception of people about it was negative. Over a period of last ten years, lot of work has been undertaken with the focussed on Fly Ash. The potential of the fly ash has been understood & brought to the fore, the utilisation areas known earlier have been further strengthened by way of undertaking Technology Demonstration Projects and facilitating multiplier effects, awareness has been created among the user agencies through dissemination of information and many more new areas of ash utilisation have been developed.
Fly ash should be considered as an essential ingredient of concrete and not merely for replacement of cement or reduction in cost. Over a period of last ten years, the image of fly ash has completely been changed from a “Polluting Waste” to “Resource Material”. The economic worth of fly ash has been understood by the people and it has now become a “sought after material”.
There is a need for concerted effort to promote the “technically sound”, “environmentally safe”, and “economically justified” utilization of Ash. A number of researches and projects on high levels utilization of Ash have been carried out in many part of world, however, the majority of which have not yet been commercialized. It should be emphasized that transforming such laboratory- or pilot-scale technologies into industrial productivity is of the highest priority for increased use of Ash.

The main of this Studies On Economical Configuration Of Rcc And Prestressed Shell Roofs report is to identify the configuration of different directrices of Pre-stressed cylindrical shell roofs that will result in the least cost for a given load and span. To identify the configuration of different directrices of RC Conoidal shell roofs that will result in the least cost for a given load and span. To study the influence of the amount of dip in the case of Hyperbolic Paraboloid –Inverted umbrella (Square and Rectangle) type shell roof. The most economical configuration of Pre-stressed cylindrical shell roofs having different directrices to cover a given area, the following types of cylindrical shell structures are Circular Directrix, Parabolic Directrix, Inverted catenary Directrix, Cycloidal Directrix.
Curved surface having small thickness compared to the radius and other dimensions. Shells or skin space roofs are preferable to plane roofs since they can be used to cover large floor spaces with economical use of materials of construction. The use of curved space roofs requires 25 to 40% less materials than that of the plane elements. The report gives Advantages and Disadvantages of shell roofs. Shell roofs are chosen commonly for covering large clear areas using the minimum of intermediate supports. Finally this report gives detail explanation on Objects of Pre-stressing, Advantages of Pre-stressing, Methodology Adopted, and Examples of Pre-stressed.
This report gives considerable design and strength are achieved by the eccentric application of the pre-stressing pressure. Design eccentricities are varied only slightly, variation from design stresses could be such as to affect the performance of a shallow unit under complete working load. The materials require that the initial stresses at pre-stressing be at the allowable upper limits of the material. This imposes high stresses, utilise the optimum stress capability of both the concrete and steel, it is necessary to ensure that these materials meets the design requirements.

Students Industrial Work Experience Scheme (Siwes) Project Report is an effective instrument for exposing students to the realities of the work environment in Nigeria especially, and the world in general; in their chosen professions so as to achieve the much needed technological advancement for the nation. To give an account of the activities carried out during the scheme, the trainee submits a technical report stating, in details, all the knowledge and experience gained.
This report gives a detailed explanation of all the activities carried out by the trainee. Before giving details of these activities, general background knowledge, as studied from relevant engineering texts available, is briefly explained. Then followed by the details of these activities, with each project been involved in outlined under each chapter. Thereafter the chapter that explains the various problems encountered in executing the afore-mentioned projects and the solutions proffered to solve those problems.
The SIWES was established as a result of the realization by the Federal Government, in 1971, of the need to introduce a new dimension to the quality and standard of education obtained in the country in order to achieve the much needed technological advancement; because it has been shown that a correlation exists between a country’s level of economic and technological development, and its level of investment in manpower development (Oniyide, 2000).
Hence, to explain the details to the student the trainee should have the complete knowledge and experience, to expose students to latest developments and technological innovations in their chosen professions. The trainee also has to provide, opportunities for the students to be involved in the practical aspect of their respective disciplines. Thus, bridging the gap between the theoretical aspects taught in the class and the real world situations.

The Sheet Metal Drawing Btech CIVIL Project Idea deep drawn technology is one of the most challenging processes in manufacturing. The sizes, shapes, thickness and deep drawn metal used to produces sheet metal deep drawn parts cover a diverse range of variables. Individual variables should be evaluated carefully to determine the optimum manufacturing method. The deep drawing of irregular square cup was investigated in this paper. To predict the damage of irregular square cup, different blank hold forces and blank shapes were studied in the numerical model.
The experiment was carried out with the optimized blank force holder and blank shapes, the crack and thickness distribution were investigated. The results of the experiment accorded with those of the numerical simulations, which show the validity of the simulation to predict where the damaged zones will appear in the part during the deformation. Many objects, such as cardboard and metal boxes, cake pans, mail boxes, HVAC ducts, roof gutters, are made from flat sheet material that, when folded, formed, or rolled, will take the shape of an object. Since a definite shape and size are desired, a regular ortho-graphic drawing of the object is made first: then a development drawing is made to show the complete surface or surfaces laid out in a flat plane.
The sheet metal deep drawn technology is one of the most challenging processes in manufacturing. The sizes, shapes, thickness and deep drawn metal used to produces sheet metal deep drawn parts cover a diverse range of variables. Individual variables should be evaluated carefully to determine the optimum manufacturing method. Regardless of the many factors involved affecting the draw quality, the most important element to a successful sheet metal deep drawing operation is the smoothness of sheet metal flow. The following are key elements affecting metal flow during deep drawing process and each of them should be considered when designing or troubleshooting sheet metal deep drawing stamping tools.

Slip Forming Civil Seminar Topic: Civil engineering course put more attention to concrete and reinforcement while almost ignoring the major component like form work. No attention is paid to economic design of form work. Form work costs approximately 10% of the total cost of the construction projects but at the same time sheltering/scaffolding involves major capital investment.
The construction industry today lacks Engineers who can design a good form work system. There are enough Engineers to do concreting, reinforcement and a structural design but there are not many to improve upon the form work. The procedures so far have been mainly hit and trial at least for the smaller construction companies. In spite of being such a major capital cost component, no enough research has been done to minimize the cost of form work.
The increasing shortage of skilled carpenters, the cost of timber and economic disadvantages of economic disadvantages of traditional purpose built forms have made the use of SLIP FORMING is necessary. So that revolutionary technique called SLIP FORMING is in introduced. Slip forming is technique of construction using mechanized form work. Slip forming is process of continuous lifting of form work by a hydraulic system of jacks and pumps.
With the invention of slip forming technique and due to speedier completion of work by the technique, there are substantial savings in cost in terms of wages and interest. This technique has no comprises against quality control and Homogeneity of structure. The cost saving will not appear automatically just because slip forming has been used .This technique has a lot of scope for improvement. But it can be adapted for tall framed structure. For slip forming work ordinary concrete of equally M20 &M25, rarely M30. Generally Portland cement is used for concreting. Fast setting cement in special cases work during winter and slip form progress is chosen. After dismantling the slip form components it can be used for span more than 25 years.
