Experimental Study On Fundamental Strength Properties And Workability Of Date Palm Fibre Reinfoced Concrete

Abstract

Concrete is considered to be chief construction material. It possesses versatile properties but it
is not independent of the weaknesses. Concrete is strong in compression but it is week in tension in order
to improve tensile strength of concrete various attempts are made one of the options is to add the fibers in
concrete . This study is paying attention on to investigate experimentally the effect of date palm fibers on
workability and fundamental strength properties of concrete. Date palm fibers of ½” and 1” length are
added from 1% to 5% by weight of cement in concrete of 1:2:4 proportion with 0.5 w/c ratio is cast and
tested. The effect of length and dosage of date palm fibers is investigated in terms of workability (slump
value) , compressive strength ( cube crushing strength ) and tensile strength (cylinder splitting tensile test)
these are composed with those of normal concrete without of DP fiber , Thus in all 6 batches with cube
and cylinders of standard size are cost and tested for evaluation of the compressive and tensile strength
respectively .the workability of the concrete is evaluated by adopting slump cone test .
The result reveal the effect of DP fiber on add the three studies the workability decreases with the
increase in DP fibers concrete where the compressive strength and tensile strength increases with the
addition of DP fibers but up to specific dosage the extent of enhancement in tensile strength is more
remarkable in case of tensile strength as compared to the compressive strength.
