Abstract-
The Rivers form a city’s lifeline and no other city in the country can boast of having three Rivers running through it. Karha riverfront in Baramati City is a multifunctional riverfront with majority of premises being used as Residential, Irrigation,Indusrial Recreational purposes.

The water quality of the Karha River is very low due to a large amount of untreated sewage being let into the river. Other major problem pertaining to Karha river is flooding of the river.

The project work aims to carrying out suitable river-training works and measures to reduce the river pollution, restore and maintain the river ecosystem as well as riparian ecosystem.

The aim of this project would be transform Baramati as a unique cultural platform with recreational and entertainment facilities serving the city.

Keywords– Riverfront,Pollution,Development,Ecological preservation,Public Space

High performance concrete provides high durability, strength, low water-cement ratio and longer life span of the structure. Special ingredients such as plasticizers, optimum aggregate size and fiber steel reinforcement are used to make this type of concrete admixture. This type of concrete type is used in special and complex construction structure such as bridges and tunnels. High performance concrete also helps in reducing the duration of the project, as there is low water cement ratio in making the admixture for the concrete. This type of concrete is useful for fast track construction where owner required the possession of the property as soon as possible. High performance concrete have several advantages over traditional Portland cement concrete.

First, high performance concrete provides better strength and durability. Water cement ratio majorly affect the workability of the concrete (Naik et. Al., 2012). According to Naik et al., (2012, p. 463), increase in the water cement ratio, which can be obtained by increasing the water content in the concrete admixture, increases the workability and slump ratio of the concrete.

Abstract
This study introduces a new approach for seismic assessment of existing school buildings. The proposed approach requires minimum human effort as it can be implemented by a small team of technical construction background. The approach is based on EMS-98 scale in addition to rapid survey of architectural and structural elements of existing school buildings. The study uses 64 selected public school buildings sampled from a total of 364 schools in Gaza Strip. The results showed that 50% of the surveyed schools are classified as Vulnerability class B, while 20 % are classified as Vulnerability Class A. The results were verified using the ‘probability matrix damage’ approach and showed good satisfying convergence. The results of the study are beneficial for the responsible parties who are expected to take appropriate actions related to enhancing seismic performance of Gaza Strip schools against seismic activities, due to the fact that these school buildings not only host about 450,000 students and teachers, but also serve as emergency shelters for those who lose their homes as a result of political instabilities in the region.

Keywords: Damage, Vulnerability, EMS-98, Seismic risk, structural type.

Abstract
Floating concrete is a fluid mixture of density less than water, which is suitable to build floating structures, reducing the consumption of land for buildings. This project report addresses the procedure of preparation of mix proportion of floating concrete, materials used & various test results of compressive strength at the age of 7 days & flow, for acceptance of this concrete. Also, it presents an application of this concrete for canoe construction along with a light weight but, strong reinforcement. Despite the self weight of the canoe, it can bear a certain amount of external load.

ABSTRACT – Civil engineering structures are used for various purposes like residential, industrial, transportation, commercial, etc. and are thus classified into various types. Any of construction project involves huge amount funds been invested in them. As India is expected to be next ruling nation there is great scope for construction industry in coming years. But in recent years there have been great numbers of construction failures which occurred in India which gave rise to utmost need to investigate the causes for these failures and to determine the preventive measures to prevent such failures from occurring in future by taking few learning lessons. The structural and construction safety is still an issue which exists with all the construction projects. This paper emphasizes on the types of failures and responsible causes for constructional failures in today’s construction industry. For this purpose an analyzation of causes of failure of the case study of Toopilipalem sea water intake structure was taken into account. The main aim is to minimize the problem of failure from civil engineering field by taking learning lessons from these devastating incidences.

ABSTRACT
Harm in adaptable asphalts happen because of the development of overwhelming vehicles and change in climatic conditions. The primary parameters that cause the damage of the asphalt layer are fatigue
cracking and rutting. Cracking can be prevented by maintaining specified temperature during the process of preparation of mix to laying of bituminous mixes. In this way, to keep the rutting, the groove safe blends like Stone lattice black-top also called STONE MATRIX ASPHALT (SMA) must be utilized as a part of the bituminous layers. In this undertaking SMA is chosen to check its execution in all viewpoints, for example, stability (kg), deformation (mm), , volume of voids in mineral aggregates(VMA), with the expansion of fillers. The utilization of mechanical by-items utilized as fillers enhances the building properties of STONE MATRIX ASPHALT (SMA) mixtures. The expanded solidness because of the expansion of the filler is spoken to by an expansion in the softening point, viscosity, stability, and resilient modulus, and also abatement in entrance or decrease in penetration. In this venture the distinctive fillers like glass powder, magnetite (iron pellets), cement kiln dust, and filler fly fiery debris or filler fly ash have been utilized. All out 12 sets of test examples were set up by utilizing distinctive sorts of filler having diverse sum in the mixture. The Marshall properties got for the fillers uncover that, flyash remains filler, examples have been found to display higher stability contrasted with glass powder, cement kiln dust, magnetite. What’s more, magnetite filler indicated least deformation at 6 % bitumen content and the rate of air voids were observed to be diminished with the expansion of bitumen substance.

Before doing the comparison study lets know what these terms mean.
CPCC – Cement-Polymer Composite Coated Rebars
FBEC – Fusion Bonded Epoxy Coated Rebars
CRSD – Corrosion Resistant Steel Deformed Rebars

1.0 Corrosion Control of Reinforcement bars (Rebars)
40% of failure of structures is on account of corrosion of embedded steel reinforcement in concrete. Therefore corrosion control of steel reinforcement is a subject of paramount importance.First and foremost for corrosion control is the good quality of concrete through good construction practices.

Abstract
Steel gets oxidise (corrosion) in the present of oxygen and water. Even present of oxygen in the concrete pore will not cause a corrosion at high alkaline environment. Concrete contains microscopic pores which contain high concentrations of soluble calcium, sodium and potassium oxides, this creates alkaline condition of pH 12–13. The alkaline condition leads to a ‘passive’ layer forming on the steel surface. The dense passive layer over the reinforcement prevents the alkalinity. This paper involves in the prevention of corrosion by maintaining alkalinity in concrete by using bacteria.

Key words: Reinforced concrete, corrosion, passive layer, alkaline, bacteria.

ABSTRACT
The use of quartz sand as replacement for sand is an economical solution for making the concrete resistant to weathering. The paper presents a concrete mix design procedure for partial replacement of sand with quartz sand. Present method was performed to evaluate the additional compressive, flexural strength with higher slump over conventional concrete in which sand is replaced with 0%, 25%, 50% and 100% of quartz sand by weight with 1% super plasticizers. The research also revealed that there is possibility of replacing fine aggregate with quartz sand in the production of structural concrete. The mix proportion adopted was 1:1.7:3 as per 10262:2009. Compressive and flexural strength tests were carried out to evaluate the strength properties of concrete at the age of 7 and 28 days. Modulus of elasticity tests were carried out at the age of 28 days.
