Index Terms— Polypropylene fiber, Steel fiber, glass fiber, Concrete, Compressive strength, Flexural strength, Cement, Coarse Aggregate 1 INTRODUCTION In today’s world, almost all the structures have been found to have concrete as an important building material which is a mixture of sand, cement, coarse aggregate and water. In order to con- struct bridges, dams, retaining walls, high rise building and chimneys, concrete has been an impor- tant building material. Cement is an important material in concrete, manufacture of which is expen- sive and a cumbersome process. Due to wide use it has become essential to discover new techniques to enhance its properties. Various methods are employed for this purpose but fibers have shown re- markable abilities when infused in concrete. Then this concrete is called as Fiber Reinforced Con- crete (FRC). The reinforcing fibers are randomly distributed in the Plain Cement Concrete (PCC). In this paper we are trying to develop a comparison between different fibers on various properties of INTERNATIONAL JOURNAL OF CIVIL ENGINEERING AND TECHNOLOGY (IJCIET) ISSN 0976 – 6308 (Print) ISSN 0976 – 6316(Online) Volume 4, Issue 4, July-August (2013), pp. 163-169 © IAEME: www.iaeme.com/ijciet.asp Journal Impact Factor (2013): 5.3277 (Calculated by GISI) www.jifactor.com IJCIET © IAEME

Here, we have taken compressive strength and flexural strength into account while varying the dosages of fiber used. Polypylene fiber is varied from 0% to 0.45%, steel fiber is ranged from 0% to 2% and glass fiber dosages are inbetween 0% to 0.04%.The compressive strength is tested for 3 days, 7 days and 28 days while flexural strength is tested for 7 days and 28 days. Respective graphs are plotted to show the comparison. 2 METHOD AND MATERIALS 2.1 Cement: Ordinary Portland cement of 53 grade of 28 days compressive strength of 48.7 MPa, satisfying the requirements of IS: 12269–1987. The specific gravity of cement was found to be 3.16.Cement is tested for various properties. The results have been showed in Table 1. These various properties include consistency, initial setting time, final setting time, specific gravity, fineness and soundness. Table 1 Sr. No. Test Value 1. Consistency 31% 2. Initial Setting Time 159 minutes 3. Final Setting time 480 minutes 4. Specific Gravity 3.16 5. Fineness 2% 6. Soundness 2 mm 2.2 Fine Aggregate: The sand generally collected from the River bed,sand is the main component of the concrete that material passing through 4.75mm IS sieve, that is grading zone-II of IS: 383-1978 was used with fineness modulus of 2.57,specific gravity of 2.65 and water absorption of 0.70 % at 24 hours. 2.3 Coarse Aggrgate: Mechanically crushed granite stone with 12.5 mm maximum size, satisfying to IS: 383-1978 was used. The specific gravity was found to be 2.82, fineness modulus of 7.32 and water absorption is 0.59 % at 24 hours. 2.4 Chemical Admixture: Polycarboxylate ether based super-plasticizer condensate as HRWR ad- mixture was used and specific gravity of 1.18. 2.5 Polypropylene Fibers: Crimped polypropylene fibers imported from Korea was used in the present study and the various properties of the material are given in Table 2.

CONCLUSION In the study, it can be concluded that performence characteristics of polypropylene-steel fi- bers were dependent on optimum fiber dosage upto 0.45% and 2% while for polypropylene-glass it was 0.3% and 0.04%.Any further addition of fiber resulted in loss in workability in both cases.The maximum increase in compressive strength was found to be about 24% in case of polypropylene- steel fiber on the other hand the increase was around 24.74% in polypropylene-glass fiber when compared to reference concrete.The maximum increase in flexural strength was approximately 43% in polypropylene-steel fiber reinforced concrete which was far less in comparison of polypropylene- glass fibers which accounted an increase of 49.43%.Both the fibers have shown a capability of pre- venting crack formation.Thus polypropylene-glass fiber reinforced concrete have proved to be much better than polypropylene-steel fiber reinforced concrete.
