THE EFFECTS OF REPLACEMENT OF CEMENT AND SAND IN CONCRETE BY MARBLE POWDER by Himanshu Sharma

Abstract
Marble powder (MP) is a fine powder, formed as a waste product of marble sawing and shaping and can not be recycled due to problems that effects the environment. There is a possibility of using marble powder as partial replacement of cement and sand in concrete mix. In this study, the possibility of using marble powder in cement and concrete production was examined by studying the effects of blending the marble powder with cement and sand and checking the physical properties of fresh and hardened concrete. In studying the performance of concrete, a total of eighteen concrete mixes were prepared with replacement of cement and sand with marble powder ranging from 5% to 20% at an increment of 5% by weight. For each replacement value, two classes of concrete, M-35 and M-40, mixes were prepared for both cement and sand replacement cases. The investigation indicates that replacement of cement by marble waste powder for 5% value, in concrete production, results increase in comparable compressive strength as of concrete specimens without marble powder with slight slump reduction for both M-35 and M-40 classes. Increment of replacement beyond 15%, in concrete production, results in reduction of compressive strength and slump. Replacement of sand by marble powder from 5-20% , in concrete production, results in similar and mostly enhanced performance than the control concrete specimens; with slightl increase in compressive strength and slight slump improvement in both mixes. The Split tensile strength of Cylinders are increasing with addition of marble powder up to 15% when replaced by weight of cement and after that addition of waste marble powder it decreases the Split tensile strength .

WASTEWATER TREATMENT WITH VERTICAL SUBSURFACE FLOW CONSTRUCTED  WETLAND by Sukhwinderpal Singh 

Abstract
Water is a vital natural resource and covers about one-third of surface of the earth. This is essential for multiple purposes. Its uses include drinking and other domestic uses, industrial cooling, power generation, agriculture (irrigation), transportation and waste disposal. After such anthropogenic activities, haphazard disposal of wastewater is deteriorating water bodies and the surrounding environment in the progressing world. In the modern times, there are several systems to treat municipal wastewater and one of them is Constructed wetland system. Constructed wetland system imparts natural and economical treatment to the wastewater and has been proven sustainable and effective alternative to the conventional treatment systems. In this study, performance of fabricated model of Vertical Subsurface Flow Constructed Wetland (VSFCW) on which effluent characteristics of Kitchen wastewater and Domestic wastewater like BOD, COD, TSS, Nitrates, Ammoniacal Nitrogen and TKN were studied at two different detention periods i.e. 24 hours and 3 days. The vegetation cover provided to the wetland system was Phragmites australis. Experiment was carried out from month of March to June in the temperature ranging between 30˚C-46˚C. 30% and 61.4% loss of influent through evapotranspiration was observed at 24 hours and 3 days HRT respectively and hence it is an efficient system to minimize highly polluted wastewaters. Kitchen wastewater, when treated at 24 hours HRT shows average percentage removal of 91.71% in BOD, 82.13% in COD, 93.63% in TSS, 57.48% in Nitrates, 57.30% in Ammoniacal nitrogen and 67.73% in TKN and when treated at 3 days HRT shows average percentage removal of 94.14% in BOD, 87.09% in COD, 97.26% in TSS, 86.81% in Nitrates, 83.60% in Ammoniacal nitrogen and 82.54% in TKN. Domestic wastewater, when treated at 24 hours HRT shows average percentage removal of 86.90% in BOD, 54.75% in COD, 84.66% in TSS, 65.35% in Nitrates, 65.81% in Ammoniacal nitrogen and 70.22% in TKN and when treated at 3 days HRT shows average percentage removal of 89.66% in BOD, 72.97% in COD, 93.82% in TSS, 88.95% in Nitrates, 82.59% in Ammoniacal nitrogen and 79.94% in TKN. Kitchen wastewater showed better results than Domestic wastewater. It was found that higher the organic strength of the wastewater better is the removal efficiency of the VSFCW.

PARAMETRIC STUDY OF HOWE ROOF TRUSS by Brahamjeet Singh 

Abstract
In design of steel trusses different types of geometries (Howe truss, Pratt truss, Fink truss are etc.) and sections (Angle section, Tube section, rectangular hollow section etc.) are widely used. The purpose of this job is to study the effect of different spacing, span, and pitches, in order to find out the most economical truss by comparing the use of hollow sections and angle sections. The need of this study arises where sometimes it is difficult or taking too much time to choose an effective and economical truss span spacing and pitch during design and construction period. The design was done with the help of Staad pro- V8i software using Limit State Design Method. In present work, “HOWE ROOF TRUSS” of span varying as 10m, 20m, 30m, and 40m has been analyzed for different spacing such as 3m, 4m, 6m and 8m also at the different pitches 1/4, 1/5, 1/6, 1,7 to get the desired economical truss design. In investigating the effectiveness of various truss geometries, a total of 64 truss combinations were analyzed and designed by providing the hollow square sections and angle sections. The analysis of all sets of trusses enables comparisons to be made among the various spans, spacing and pitches. The loads (dead load, live load and wind load) at each panel and node are calculated manually as per Indian Standard Codes IS 800:2007, and IS 875(Part 3)-1987 and then the loads are entered into STAAD PRO-v8i software for analysis and designing of members. Loads are applied on the nodes (member joints considered as pinned joints) of truss the STAAD PRO-v8i output method is used for determining the member forces. After that the load combinations and design were applied according to the design method (Limit State Design Method). In designing of Howe roof truss both the angle sections and square hollow sections were provided to compare the weight of truss. In this Study the truss with a least value of weight is considered as most economical truss. At the end it was concluded that with the increase in spacing of truss the self-weight of truss was also enhanced. In most of the cases the pitch 1/5 and 1/ 6 was concluded as the most economical. Most of the times the trusses provided with angle sections were assumed to be more economical. On the other hand for 30m span with pitch 1/6 the hollow sections gave the economical design of truss. Also in case of 40m span and 1/7 pitch the hollow sections are seems to be more cost effective.
