Enhancement and Implementation of Developed Polypropylene Macrosynthetic Fiber for the Improvement of Reinforced Concrete Properties | Chapter 6 | Scientific Research, New Technologies and Applications Vol. 8

This research work describes the results of collaborative research between a research institution in Kuwait and an industry partner to produce Polypropylene macro synthetic fibers (PMSF), the first of its kind in Kuwait and the Arabic Gulf area. Polypropylene macro synthetic fibers used for reinforcement in concrete result in longer concrete service life due to better crack control and corrosion resistance, making these fibers an excellent alternative to conventional steel reinforcement for slab-on-grade construction. This research study aimed to determine the optimal dosage of PMSF within a concrete mix and to evaluate the effect of their inclusion on the mix properties of concrete. Different percentages of the selected fiber were included in the preparation of concrete mixes. The developed fibers satisfied the requirements for qualifying and using fibers in fiber-reinforced concrete. It was concluded that PMSF at a dosage of 6% showed a maximum advantage in terms of post-crack performance. Therefore, the developed fibers satisfied the requirements for qualifying and using fibers in fiber-reinforced concrete.

Assessment of Behaviour of M-Sand Concrete by Addition of Different Types of Steel Fibers: An Update | Chapter 7 | Research Highlights in Science and Technology Vol. 6

 This stage assesses the behaviour of M-Sand Concrete by Addition of Different Types of Steel Fibers. Concrete being a worldwide material in the construction manufacturing is being a research material as an alternative and effective individual is being aimed upon and surplus of experimentation is limitless. The material such as M-Sand and Steel Fiber leads to important variation in strength limits of concrete. The objective search out achieve necessary charactertics such as substance, durability and workability in an careful manner. The use of made sand a suggestion of choice to natural soil in the production of concrete results in cost funds and an improvement in substance metrics. Concrete gains substance as a result of the use of miscellaneous steel fibre kinds, containing crimped steel fibres. In this paper stating beliefs M-Sand is replaced by Natural Sand entirely along with various proportion of crimpled steel fibers that is 0.00%, 0.50%, 1.00%, 1.50%, & 2.00% as different oppose nominal rude aggregate and OPC 43 grade of cement. The research works shows that crimped fortify fiber at 1.50% the compressive strength of actual increases because of the increase in crimped gird fiber on account of which relation between void are discounted.The concrete prepared will be of M25 grade hardened by adopting IS code arrangement. With varying portion of steel fibre apart from M-Sand the proportion have varying substance. It has been decided that the concrete qualified by using M-Sand as substitute of fine aggregate gives uniform workability throughout the join.
