WE HAVE FOUND THAT BY ADDING 2% AND 4% OF GLASS FIBRE IN CONCRETE MIX AND INSTEAD OF RIVER SAND AND M-SAND WE HAVE USED ECO SAND TO ACHIEVE STRENGTH IN CONCRETE IN RESPECTIVE DAYS (7 AND 28 DAYS)
2. ABSTRACT
In this project work, An investigation on glass fiber
reinforced concrete using eco sand is carried out. An
exploratory study on physical properties of above said
reinforced concrete were carried out. A large number of
concrete cubes of desirable size 150×150×150 mm with the
addition of 2% and 4% glass fiber and cylinder mould of
desirable size 150×300 mm with the addition of glass fiber
of 2% and 4% were casted. Compressive and split tensile
test were carried out and their properties were determined as
per the standards. On addition of 2% and 4% of glass fiber,
compressive strength and tensile strength of reinforced
concrete mixture increased considerably.

5. GLASS FIBRE
• Glass fibre is a material
consisting of numerous
extremely fine fibres of
glass. Glass fibre-
reinforced concrete
consists of high-strength,
lightweight, durable,
alkali-resistant glass fibre
embedded in a concrete
matrix. Glass fibre of
12mm length is been
used.

22. CONCLUSION
• Based on limited experimental investigation on glass fiber
reinforced concrete using eco sand , the following observations are
made through on physical properties of concrete.
• Cubes of desirable size 150×150×150 mm with the addition of 2%
and 4% glass fiber and cylinder mould of desirable size 150×300
mm with the addition of glass fiber of 2% and 4% .
• It is observed that compressive and tensile strength of concrete on
addition of 2% of glass fiber shows increment in strength more than
addition of 4% of glass fiber.
• Obtained results are drawn in terms of graphical forms and
presented for better understanding and further scope of
experimentation.
