Durability Testing of Fibrous (Cement Bags) Concrete for Sulphate Attack

The present work is aimed to study the effect of sulphate on compressive strength of Normal concrete of M-40 grade as well as on fibrous concrete of grade M-40. The fibrous concrete was achieved by adding 0.5 % of polypropylene fibers (obtained from cement bags) by weight of dry aggregates in the concrete mix. Concrete cubes of size 150mmX150mmX150mm were casted for testing the compressive strength of the concrete mixes. The cubes were immersed in sulphate solutions after 28 days of normal curing and the reduction in compressive strength and weight was obtained for 30 and 60 days. The results show that fibrous concrete showed better performance as compared to the normal concrete when exposed to the sulphate environment.
