An Experimental Work on Green Blocks Composed of Industrial Waste Materials with Polypropylene Fiber.

Abstract

More recently fibers such as those used in traditional composite materials have been
introduce to increase it’s toughness or ability to resist crack growth. Compared with full-dispersed
polypropylene fiber has advantages in its thinness, large amount, non-water absorbency, strong acid
& alkali resistance and similar elastic modulus with that of concrete. Mainly application is Increase
seepage resistance, Improve steel protection, Increase cracking resistance, Increase fire resistance,
Strengthen spurt & fatigue, Improve plastic deformity. And It’s uses are Projects like concrete road,
bridge, airport road and factory floor which strictly require cracking resistance. In this research
study aim is comparison of compressive strength between normal mix concrete & green concrete
blocks composed by locally available waste materials with Polypropylene fiber and reduce the cost
of concrete. In this research study the (OPC) cement has been 50% replaced by waste ceramic
powder by weight of M-30 grade concrete & fine aggregate (sand) has been 25% replaced by waste
tyre rubber by weight of M-30 grade concrete and also used polypropylene fiber as a additional
material. Concrete mixtures were produced, tested and compared in terms of compressive strength,
Split tensile strength and Flexural strength to the conventional concrete. These tests were carried out
to evaluate the mechanical properties for 3, 14 and 28 days. Then after 3, 14, & 28 days of curing
work, we will perform analysis and measure compressive strength, Split tensile strength and Flexural
strength in normal mix concrete and green blocks with polypropylene fiber concrete.
