natural fiber reinforced concrete

Concrete is the most widely used construction material in the world and steel reinforcement is always required to meet tensile strength and ductility demands of concrete structures. The production of concrete and reinforced concrete structures creates lots of environmental issues associated with the significant release of CO2 and other greenhouse gases. In addition, the corrosion of steel reinforcement is one of the major challenges that current civil engineers are facing. In the United States, the upgrading o ....etc

ABSTRACT
Road 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 pa ....etc

xperimental results on ?ber micro-buckling of continuous glass-?ber reinforced hollow-cored recycled plastic extrusions under creep tests are introduced. The full size specimens with dimensions in 2:5 3:5 42 in:3 were submerged in warm water at a temperature of 125 F when they were under a four-point bending creep test. The results show that the micro-buckling of the embedded glass-?ber roving occurs along 90% the length of the specimen on the upper inner surface (compressive side) and mainly during the time between 5 and 100 h from the init ....etc

I m Surya doing my final year in civil engineering. I have chosen to work on fiber reinforced Geo polymer concrete for my final year BE project. I would like to know the tests to be performed to assess the properties , instruments required and feasibility of the project. I'd be much obliged if someone could help me.

GLASS FIBER REINFORCED CONCRETE

ABSTRACT:-
Glassfibre Reinforced Concrete or GRC is one of the most versatile building materials available to architects and engineers. Composed principally of cement, sand and special alkali resistant (AR) glassfibres, GRC is a thin, high strength concrete with many applications in construction.
The GRC-Glass Fibre Reinforced Concrete, which was first invented by 'pilkington' in UK and developed successfully by rest of the continent, is a product having unique combination of properties unch ....etc

What is a Fiber ?
Small piece of reinforcing material
possessing certain characteristic
properties.
Can be circular or flat.
Parameter used to describe fiber
Aspect ratio .
Aspect ratio is ratio of its length to its
diameter.
Typical aspect ratio for fibers ranges from
30 to 150.
Concrete (FRC)?
Fiber reinforced concrete (FRC) is concrete
containing fibrous material which increases its
structural integrity.
It contains short discrete fibers that are uniformly
distributed and ....etc

ABSTRACT

TOPIC : HELICALLY COILED HEAT EXCHANGERS

Process heat transfer with conventional shell and tube heat exchanger
is familiar to many engineers in many industries.Their use and performance is well-dominated. However, helically coiled heat exchangers, although they have been around for many years, are not well known.

Although various configurations are available, the basic and most common design consists of a series of stacked helically coiled tubes. The tube ends are connected to manifolds, which act as fluid entry and ....etc
