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.

Numerical Development and Validation of a Polyethylene Component Injection Mold| Chapter 6 | Techniques and Innovation in Engineering Research Vol. 7

 Foam needle molding is a variant of the unoriginal injection decoration that uses a chemical blasting agent (CBA), to produce a absorbent core. The always-increasing client demands for quality and cheap have led to the necessity of best possible status in injected parts. In view of this, mold designers are utilizing Finite Element Method (FEM) models to optimize the process. This work aims to design a mold for needle of a large give up chemical tumbling agent. In the mold design, 3D imitation software is used to call possible questions that would exist in the mold and to present the benefits of injecting with the tumbling power. The injected component is a abundant-dimensions extreme-density polyethylene (HDPE) cot. The mold was fabricated and the first parts had few problems of accent in the area of the hydraulic pins, that led to a change of the adjustment of these parts. However, the project was successfully achieved and it is currently functional.

Some Practical Aspects of Oxidative Stability of Polypropylene Tubes Characterized by DSC | Chapter 8 | Current Research and Development in Chemistry Vol.3

The oxidation time and oxidation temperature of a total of 20 specimens with unknown pre-history
from various manufacturers of polyethylene and poly(ethylene-co-propylene) are determined. The
specimens are in the form of fittings used in piping. The specimens are divided into two groups
corresponding to their melting temperature and polyethylene content in the copolymer, respectively.
The oxidation activation energy for the two groups is calculated. Reasonable relationship between the
measured oxidation time and the time, calculated on the base of the measured oxidative temperature,
is obtained. The scattering of experimental data is thoroughly examined and some recommendations
aiming at improving the results are suggested. Specific recommendations are given for the cases of
technological and post consummative piping waste. The paper critically estimates the accuracy in the
measured oxidation time and temperature as well as their mutual relation.

Assessment of Concrete Mixes Replaced with Fly Ash and Reinforced with Steel and Polypropelene Fibres: Advanced Study | Chapter 12 | Emerging Trends in Engineering Research and Technology Vol. 6

This paper presents a series of tests for characterizing the structural behavior of fibre reinforced concrete subjected to different loading. The experimental program involves investigation of fly ash replaced concrete with two types of fibres i.e. Steel fibre and polypropylene fibre. Plain concrete and conventionally fly ash replaced reinforced concrete specimens have also been casted and tested in the laboratory. The mechanical properties of Conventional M30 grade of concrete and concrete with cement replaced by fly ash and reinforced with steel and polypropylene fibres of three volume fractions of 0.2% to 1.4% are studied. This research is to study about the mechanical properties of fly ash with steel and polypropylene as a strengthening material.
