Abstract

Aim: The major objective of this study is to increase the strength of ordinary cement concrete by adding novel polypropylene fiber by cement weight.
Method: A study of the impact of extra novel polypropylene fiber in regular Portland cement concrete has been attempted in an effort to enhance these attributes of plain concrete. Results: Through the use of a compressive strength test at 28 days for concrete of the M25 grade, 4% of fibers in this experimental inquiry have been examined for their impact on the strength characteristics of concrete. The concrete cube mould size was taken as 150 mm x 150 mm x 150 mm cubical steel mold. The findings of the tests indicate that concrete with novel polypropylene fiber performs better than concrete alone. With the addition of novel polypropylene fiber to regular Portland cement concrete, the findings have shown an increase in compressive strength. Concrete added with novel polypropylene fiber at 4% had a mean compressive strength of 30.24 N/mm2 , compared to conventional concrete’s 27.46 N/mm2 . The outcomes were examined using an independent sample t-test. Two groups of 36 samples taken for the test. The novel polypropylene fiber standard deviation for concrete was 4% and was 0.91737. The SPSS carried out has a significance of 0.000 (p < 0.05). This shows that there are the two groups’ statistically significant differences considered in this study. Conclusion: The results of the experimental study led to the conclusion that adding fibers to the concrete mixture very slightly increases the compressive strength.
