Retrofitting Of Rc Beams With Externally Bonded Simcon Laminates

This Retrofitting Of Rc Beams With Externally Bonded Simcon Laminates project report presents the results of experimental studies concerning the flexural strengthening of RC beams using externally bonded Slurry Infiltrated Mat concrete (SIMCON) laminates. A total of four reinforced concrete beams were cast and tested in the laboratory over an effective span of 3000 mm. Three beams were strengthened with bonded SIMCON laminate at the bottom under virgin condition and tested until failure; the remaining one beam was used as control specimen. Static responses of all the beams were evaluated in terms of strength, stiffness, ductility ratio, energy absorption capacity factor, compositeness between laminate and concrete, and the associated failure modes.

retrofitting-of-rc-beams-with-externally-bonded-simcon-laminatesComparison was made between the Control specimen and strengthened beam. The results show that the strengthened beams exhibit increased flexural strength, enhanced flexural stiffness, and composite action until failure. The cost of civil infrastructure constitutes a major portion of the national wealth. The rapid deterioration of reinforced concrete structures has thus created an urgent need for the development cost-effective methods for repair, retrofit and new construction.

As the number of civil infrastructure systems increases worldwide, the number of deteriorated buildings and structures also increases. Complete replacement is likely to be an increasing financial burden and might certainly be a waste of natural resources if upgrading or strengthening is a viable alternative.

Conclusion:

SIMCON laminates properly bonded to the tension face of RC beams can enhance the flexural strength substantially. The strengthened beams exhibit an increase in flexural strength of 45.0% as compared to the Control beam (CB1). At any given load level, the deflections are reduced significantly thereby increasing the stiffness for the strengthened beams. A flexible epoxy system will ensure that the bond line does not break before failure and participate fully in the structural resistance of the strengthened beams.

Real Time Automatic Irrigation System Project Report

This Real Time Automatic Irrigation System Project Report is about the Real Time Automatic Irrigation System. The report consists of Introduction, Block Diagram, Interfaces, Soil Moisture Sensor, Solenoid Valve, Relays. The continuous increasing demand of food requires the rapid improvement in food production technology. In a country like India, where the economy is mainly based on agriculture and the climatic conditions are isotropic, still we are not able to make full use of agricultural resources. The main reason is the lack of rains & scarcity of land reservoir water. 

real-time-automatic-irrigation-system-project-reportThe continuous extraction of water from earth is reducing the water level due to which lot of land is coming slowly in the zones of un-irrigated land. Another very important reason of this is due to unplanned use of water due to which a significant amount of water goes to waste. Agriculture is the oldest occupation in the world. We are unable to make full use of agricultural resources. The main reason is the lack of rains and scarcity of land reservoir water. This project helps in time saving and removal of human error in adjusting available soil moisture levels. The goal of this project is to automate the irrigation system with the help of wireless communication. Before having an automatic irrigation system installed, land owners usually are advised to conceptualize and map out a landscape design plan. This map or blueprint will determine the amount of water each lawn section will need.

real-time-automatic-irrigation-system-project-report1The report explained the Real Time Automatic Irrigation System through block diagram. Under interface the sensor, relay and Zigbee interface is defied very clearly and pictorial way. Irrigation is the artificial application of water to the soil usually for assisting in growing crops. In crop production it is mainly used in dry areas and in periods of rainfall shortfalls, but also to protect plants against frost.

TYPES OF IRRIGATION

1. Surface irrigation

2. Localized irrigation

3. Drip Irrigation

4. Sprinkler irrigation

Conclusion:

The Microcontroller based irrigation system proves to be a real time feedback control system which monitors and controls all the activities of drip irrigation system efficiently. The present proposal is a model to modernize the agriculture industries on a small scale with optimum expenditure. Using this system, one can save manpower, water to improve production and ultimately profit.

This report focuses on visible symptoms of the problem rather than on visible and invisible problems as well as the possible causes behind them. This report focuses about the repair materials and the techniques used since the use of appropriate repair materials and techniques is essential for the satisfactory performance of the repaired structure. This report presents an analysis of concrete illnesses, curing treatments, and problems leading to unsatisfactory performance of repaired concrete structures.

Provides prescriptive advice for engineers on the repair and maintenance of reinforced concrete structures damaged by reinforcement corrosion. It covers:

i. The mechanisms of corrosion of reinforcing steel in concrete,

ii. The diagnosis of deterioration in concrete structures, including the planning and interpretation of defect investigations,

iii. Some of the options for repair, each with its prognosis for future service life and maintenance requirements,

iv. The types of materials used to repair the damage and protect against future deterioration, and

v. Preventive maintenance.

The deterioration mechanisms described and most available repair options apply, in principle, to all forms of concrete with embedded steel reinforcement. This report is primarily aimed at non-pressurised reinforced concrete.

Conclusion:

Repair and prepared corrected area should be carried out systematically. Applications of protective coatings are required to be properly supervised and carried out. Surface defects like bugs holes and honey comb require immediate repairs.

Primary Treatment Of Waste Water Fundamental Of Environmental Engineering

This Primary Treatment Of Waste Water Fundamental Of Environmental Engineering project report is about the Treatment of Waste water Fundamental. The process of removing contaminants from wastewater and household sewage, both runoff and domestic is called Wastewater treatment. It includes physical, chemical, and biological processes to remove physical, chemical and biological contaminants. Its target is to develop an environmentally-safe fluid waste stream and a solid waste, suitable for disposal or reuse (usually as farm fertilizer).

Under Preliminary “Treatment” define about Equalization to Smooth out fluctuations in flow rate. The Flow Measurement contains efficient operation, chemical addition, etc. After pumping, the plant is designed to operate under gravity flow to the point of discharge at the receiving stream. The Primary treatment includes Bar screen, Comminatory, Grit chamber, Primary clarifier. The report defines the details of each Primary treatment separately.

The purpose of disinfection in the treatment of waste water is to substantially reduce the number of microorganisms in the water to be discharged back into the environment for the later use of drinking, bathing, irrigation, etc. The effectiveness of disinfection depends on the quality of the water being treated for example cloudiness, pH, etc. Types of disinfection being used, the disinfectant dosage, and other environmental variables. Cloudy water will be treated less successfully, since solid matter can shield organisms, especially from ultraviolet light or if contact times are low. Generally, short contact times, low doses and high flows all militate against effective disinfection.

Conclusion:

As per the common methods of disinfection include ozone, chlorine, ultraviolet light, or sodium hypochlorite. After multiple steps of disinfection, the treated water is ready to be released back into the water cycle by means of the nearest body of water or agriculture. Afterwords, the water can be transferred to reserves for everyday human uses. The pictorial presentation of Primary treatment is helps to understand the concept of the Treatment of Waste water.

Project Report On Polymer Fibre Reinforced Concrete Pavements

This Project Report On Polymer Fibre Reinforced Concrete Pavements is about the POLYMER FIBRE REINFORCED CONCRETE PAVEMENTS. In a developing country such as India, road networks form the arteries of the nation. A pavement is the layered structure on which vehicles travel. It serves two purposes, namely, to provide a comfortable and durable surface for vehicles, and to reduce stresses on underlying soils. In India, the traditional system of bituminous pavements is widely used.

project-report-on-polymer-fibre-reinforced-concrete-pavementsRoad transportation is undoubtedly the lifeline of the nation and its development is a crucial concern. The traditional bituminous pavements and their needs for continuous maintenance and rehabilitation operations points towards the scope for cement concrete pavements. There are several advantages of cement concrete pavements over bituminous pavements. This paper explains on POLYMER FIBRE REINFORCED CONCRETE PAVEMENTS, which is a recent advancement in the field of reinforced concrete pavement design. PFRC pavements prove to be more efficient than conventional RC pavements, in several aspects, which are explained in this paper.

Polymeric fibres are being used now because of their no risk of corrosion and also being cost effective. Polymeric fibres normally used are either of polyester or polypropylene. Polymer fibre reinforced concrete (PFRC) was used on two sites with ready mix concrete and Vacuum dewatering process.

Conclusion:

PFRC can be used advantageously over normal concrete pavement. Polymeric fibres such as polyester or polypropylene are being used due to their cost effective as well as corrosion resistance. PFRC requires specific design considerations and construction procedures to obtain optimum performance. The higher initial cost by 15-20% is counterbalanced by the reduction in maintenance and rehabilitation operations, making PFRC cheaper than flexible pavement by 30-35%. In a fast developing and vast country like India, road networks ensure mobility of resources, communication and in turn contribute to growth and development.
