An Experimental Investigation on the Strength and Workability Characteristics of Polypropylene Fiber Reinforced Tertiary Blended Concrete Using Industrial Wastes

Abstract

An Experimental Investigation On The Strength And Workability Characteristics Of Polypropylene Fiber Reinforced Tertiary Blended Concrete Using Industrial Wastes Over the past several years, extensive research on concrete technology has been underwayaround the globe in finding other materials that can partially or completely replace ordinary Portland cement (OPC) and can also meet the requirements of strength, workability and durability aspects.

Consequently, these have led to the growth of binary, ternary and tertiary mixed concrete depending on the number of CCMs and their combinations used as partial cement replacement materials. Over the past several decades, extensive research on concrete technology has been underway around the globe in finding alternative materials that can partially or fully replace ordinary Portland cement (OPC) and can also meet the requirements of strength and durability aspects.

These have subsequently led to the development of binary, ternary and tertiary mixed concrete depending on the number of CCMs and their combinations used as partial cement replacement materials.

Conclusion

The compressive strength of the combination of 10% MK with 20% GGBS showed an increase from 19.06 to 22.76% with different fiber percentages Among the different percentages of steel fibers, i.e. 0.5 percent, 1.0 percent, 1.5 percent, 2.0 percent, the optimum percentage of higher compressive strength is 2.0 percent. The percentage of steel fiber is therefore confined to 2 %.

The tensile strength showed an increase from 13.54 to 57.42 percent with various percentages of fiber for this combination of 10 percent MK with 20 percent GGBS. As the percentage of steel and glass fiber increases, there is a marginal increase in compressive strength and a higher increase in tensile strength. The tensile strength obtained for a mix with 2 percent fibers was 8.24 MPa.
