As construction industries are increasing at faster rate consumption of naturally available sand is more now-a-days. The fine aggregate which we use for construction is available from natural rivers and streams use of large amount of fine aggregate affects the environment. This present study had been carried out to investigate the possibility of utilizing a broad range of concrete raw materials as partial replacement for fine aggregate in the production of concrete. In this study replacement of fine aggregate with steel slag, M-sand and bottom ash with 10%, 20%, 30%, 40%and 50% for grade of concrete M30are tested for finding fresh and hardened properties of concrete to identify the optimum percentage of three fine aggregate replacement materials in concrete. M30 grade of concrete tested in compressive strength at the age of 28, 56, 90 and 180 days, flexural strength and modulus of elasticity at the age of 28 days curing and also to determine the durability properties of replacement materials concrete. Rapid Chloride Penetration Test, Salt resistance and Sulphate Resistance are to be conducted. Using origin pro software to arrive formulate regression equations for the properties of concrete.

Due to lack of plain terrain in Shimla, it offers sloppy terrain for construction site. Behaviour of buildings on sloppy terrain behaves different than the building on the plain terrain. Past construction practices in Shimla includes common irregularity such as soft storey, mass irregularity, torsional irregularity, unsymmetrical layout of plan, vertical irregularity and pounding. Over the past earthquakes and research papers have shown that RC buildings in sloppy terrain affects more. The present study investigates the irregularities (Table 4&5 of IS 1893 (Part-1): 2002) in the RC construction practices in hilly region (Shimla). The behaviour of (G+3) storey building with regular and irregular configurations is checked for the linear and non linear analysis based on studies that had done.

Peak discharge Determination is one of the most important studies for Irrigation projects. The proposed of hydrologic design is to estimate maximum, average or minimum flood which the structure is expected to handle .This estimate has to be made quite accurately in order that the project can function properly. To estimate the magnitude of a flood peak the following alternative methods are available academically. In this study Hydrological analysis has been conducted based on 10years maximum daily rainfall data .The frequency analysis has been carried out by different methods and Log Pearson type III method is adopted .The peak discharge computed by United States Soil Conservation Service (USSCS) method is 1278m 3 /sec .Since this method over estimates the design flood, we adopt the peak discharge calculated by slope -area method.

The processes involved in the local scour due flow contraction are so complex that it is difficult to establish a general empirical analytical model to provide accurate estimation of scour. In this paper, the capacity of an Adaptive-Network-Based Fuzzy Inference System (ANFIS) for predicting equilibrium contraction scour depth in alluvial channels was investigated. The main subject of this work is to design an appropriate neural network architecture for training the ANFIS from a given set of input and output data. The training algorithms used in this work are (1) basic hybrid method, (2) basic backpropagation with gradient descent method, (3) backpropagation with momentum method, and (4) backpropagation with Levenberg-Marquardt method. Applying a self-developed software, the numerical experiments were carried out by combining these training algorithms with different ANFIS structures. Statistical indices of model performance such as mean average error, root mean squared error, and coefficient of correlation were measured for each combination. The results showed that among all given models the zero order Takagi-Sugeno’s model with four bell-shaped membership functions for each input and the Levenberg-Marquardt algorithm for training provided the best performance for estimating of contraction scour depth.

Ordinary steel propeller-shafts are usually manufactured in two or more pieces to increase the basic bending natural frequency because the bending natural frequency of a shaft is (when one number goes one way, the other number goes the opposite way) to the square of beam length and (fair in amount, related to/properly sized, related to) the square root of clearly started/ particular modulus. Therefore the steel propeller shaft is made in two sections connected by a support structure, bearings and U-joints and because of this over all weight of composite materials. Composite (made up of different things) materials (Glass Epoxy) were used and designed and analyzed for their appropriateness in terms of torsional strength, bending natural frequency, torsional buckling and number of cycle by comparing.

Much attention has been made towards adsorbent materials to be used in heavy metal removal from polluted water and various techniques are applied such as chemical, physical and biological techniques. This study was designed for using less expensive and much frequently available materials (mango peels, Neem leaves & coconut husk) to remove iron, copper and cadmium from water. Current data show that all adsorbents used are capable of removing copper, iron and cadmium ions at significant capacity. Furthermore, coconut husk had higher capability than mango peel and neem leaves.

Pervious concrete is a special high porosity concrete used for roads carrying light traffic, allows the water from precipitation and thereby reducing the runoff from a road surface and hence recharging ground water levels. Objective of this research is to find mechanical properties i.e. compressive strength, split tensile strength and flexural strength of the pervious concrete. The main problem of pervious concrete pavement is the strength itself. The conventional and pervious concrete is tested for 28 days of curing period with fresh water & salt water. For conventional concrete the mix proportion is considered as 1:1.5:3 and that of for pervious concrete 1:4. Water cement ratio of 0.3 for both conventional and pervious concrete is adopted. Fresh water (FW) is a tap water and salt water (SW) is prepared by adding of common salt (2.5%), detergent (2.5%) by volume. From experimental results, it is observed that use of salt water for curing of concrete, improved the mechanical properties of both the conventional and pervious concrete for the period of 28 days.
