EXPERIMENTAL INVESTIGATION ON ADDITION OF POLY VINYL ALCOHOL FIBER IN LIGHT WEIGHT

CONCRETE

Abstract

The cementations paste of cement and fine sand with a multitude of micro/macroscopic discrete air cells uniformly distributed throughout the mixture is said to be as Light weight concrete. The light weight concrete has 28-day compressive strength of 10-15 MPa for the same proportion of constituents in conventional concrete by volume.

Research has found that cement paste’s strength can even exceed the strength of the coarse lightweight aggregate. With strong cement paste, the coarse aggregate can get crushed under high loading before the paste/aggregate interface breaks.

As the lightweight aggregate are usually weaker than cement matrix and provides little resistance to crack propagation and also lesser strength aspects. To improve ductility into lightweight concrete, various fibers, including steel, carbon, glass, nylon and propylene (PP) fibers, have been introduced into the mixes. While improvements in tensile strength, flexural toughness are observed, the behavior of this fiber reinforced lightweight concrete.

The object of the present study is to develop a lightweight version of ECC materials (Poly vinyl fibers) i.e. a lightweight fiber reinforced cementations composite having high strain capacity in tension with strain hardening behavior and high strength in both tension and compression. While weight reduction approaches by varying proportions of Poly vinyl fibers accordingly. The results have to be taken on the influences of the lightweight fillers upon the workability, interface bond properties, fiber dispersion and composite strength.

Keywords: ECC (Engineered Cementious Composite), polyvinyl alcohol fibers, High strain capacity.
