IIJ08-01: STABILISATION OF SUBGRADE SOIL USING POLYPROPELENE FIBER
AUTHORS: Sanoj kumar, Harsh Panthi
ABSTRACT : The main objective of this study is to investigate the use of waste fiber materials in geotechnical applications and to evaluate the effects of waste polypropylene fibers on shear strength of unsaturated soil by carrying out direct shear tests and unconfined compression tests on two different soil samples. The results obtained are compared for the two samples and inferences are drawn towards the usability and effectiveness of fiber reinforcement as a replacement for deep foundation or raft foundation, as a cost effective approach.
IIJ08-02 : Power quality Improvement using UPQC for a three phase distribution system under the condition of non-linear loading and voltage dip
AUTHORS: Krishna kumar teotia , Nitesh Singh
ABSTRACT: Extensive non-linearity of loads and voltage sag, application of power electronic devices which causes harmonics in the utility system generates problems related to the quality of power delivered. Good Power Quality is immense important for both industrial and domestic sectors. To safeguard against power quality issues this paper presents a dual compensating control scheme based UPQC controller. The UPQC comprises of both shunt controller for current control and series controller for voltage regulation. The control is designed using parks transformation based pulse width modulation technique. The performance of the proposed controller is analysed under various non-linear loads and for the condition of voltage sag.
IIJ08-03: Numerical simulation to optimize the ventilation design condition of school building using CFD
AUTHORS: Devendra Veer Vikram Shahi , Mr. Arvind Gupta, Mr. Vardhan Singh Nayak
ABSTRACT : Summer air conditioning represents a growing market in buildings worldwide, with a particularly significant growth rate observed in European commercial and residential buildings. Heat-driven cooling technologies are available, which can be used in combination with solar thermal collectors to alleviate the burden caused by air conditioning on the electric utilities and the environment. Solar air conditioning has progressed considerably over the past years as a result of efforts toward environmental protection and new developments in components and systems, and significant experience has been gained from demonstration projects. The main obstacles for large scale application, beside the high first cost, are the lack of practical experience and acquaintance among architects, builders and planners with the design, control and operation of these systems. This paper describes the main results of the EU project SACE (Solar Air Conditioning in Europe), aimed to assess the state-of-the-art, future needs and overall prospects of solar cooling in Europe. A group of researchers from five countries has surveyed and analyzed over 50 solar-powered cooling projects in different climatic zones. The paper presents a short overview on the state-of-the-art and potential of solar-assisted cooling and air conditioning technologies. The results of the study, including a database of the surveyed projects, an evaluation of these projects on a uniform basis, an economic analysis tool, user guidelines and a multimedia tool—are presented. The potential energy savings and limitations of solar thermal air conditioning in comparison to conventional technologies are illustrated and discussed.

IIJ08-04 : A Study on Strength of Concrete with Replacement of Cement with Silica fume and Quarry dust
AUTHORS: Furquan Khan, Rohit Jain
ABSTRACT : Concrete a composite material made from cement, water, fine aggregate and coarse aggregate. But present researchers are in interest of finding new cement materials by waste materials or waste products produced from industries which are harmful to environment. The present paper deals with partial replacement of cement with silica fume and quarry dust which are having silica used as admixture for making concrete. In this paper we presents the results of an experimental investigation carried out to evaluate the mechanical properties of concrete mixtures in which cement was partially replaced (10%, 20% and 30%) with silica fume and quarry dust using M30 grade concrete on tested at 7, 14, 28 and 50 days. Silica fume / quarry dust is made partial replacement of cement and found that 10% and 20% of partial replacement is beneficial to concrete without loss of standard strength of cement. Making 30% partial replacement of cement with quarry dust as constant with some loss of strength of concrete and results were found that silica fume and quarry dust usage in partial replacement to cement can be made.
Keywords: concrete, silica fume, quarry dust, partial replacement, waste materials, crushing loads.
IIJ08-05: A STUDY ON THE EFFECT OF RECYCLE COATED CRUSHED BRICK & NON COATED OVER BURNT BRICK AGGREGATE ON THE STRENGTH OF CONCRETE
AUTHORS: Paresh Pagaria, Rohit Jain
ABSTRACT : A broad examination was led for reusing of devastated concrete as coarse aggregate for new developments works. Properties of reused aggregate and properties of reused aggregate concrete are abridged independently. In this examination, the consequences of examinations on some imperative issues related with reusing of obliterated concrete are condensed, for example, correlation of reused block and stone aggregate concrete. To produce an investigation on concrete which fuse Over Burnt Brick and reused covered block aggregate with wire work, concrete waste incompletely because of their bounty. 15%, 30% and 45% (M25, M30) consolidation was utilized as halfway substitution of characteristic coarse aggregate in concrete. From every one of the outcomes and test approach it is presumed that Concrete framed with over consumed block aggegate and reused covered block aggregate with wire mesh, concrete waste aggregate demonstrated helpful execution as contrasted and the concrete made up of common aggregate got from nearby assets. It lessens the expense of concrete by diminishing the aggregate expense and delivers practical infrastructure framework. It has been seen that the utilization of waste materials results in the development of light weight concrete. Employments of such waste materials won’t just chopped down the expense of development, however will likewise contribute in safe transfer of waste materials.
Keywords: concrete, over burnt bricks, coated recycled Aggregate , partial replacement coarse aggregate, wire mesh, waste materials, crushing loads.
