“…For example [7] modified the surface of PP fibres in low-frequency argon and oxygen plasma at 20 Pa. They achieved best results for 2 minutes exposition and power input 120 W. The improvement of flexural strength was 56% and the toughness (work to fracture multiplied by the width and depth of the tested sample) was improved by 54%.…”

Abstract:The plasma treatment of polypropylene fibres used as concrete admixtures for improving its mechanical properties is the focus of this research paper. A plasma treatment was conducted in a low-temperature plasma environment at atmospheric pressure in a DCSBD (Diffuse Coplanar Surface Barrier Discharge). The degree of hydrophilicity caused by the plasma treatment was determined by measuring the rate of penetration of water into the porous media, commonly referred to as the Washburn method. The influence of the addition of PP (polypropylene) fibres to the concrete matrix was investigated using a three point bending test which determined the flexural strength of concrete samples. Our experiments demostrate that plasma improves both the wettability of PP fibres and its adhesion to the concrete matrix. The tests of flexural strength show, that even a short plasma treatment (5 s) can have a significant impact on the mechanical properties of fibre-reinforced concrete composite.

“…This concept is not entirely new. Plasma treatments of PP fibres for applications in concrete mixtures have already been investigated [7,8]. However these previous studies were carried out under low pressure conditions, which makes the studies unsuitable for industrial applications.…”

“…Taking into account the fact that the wetting angle of the propylene fibres is less than 90° (Felekoglu et al 2009), it can be assumed that these fibres are not absolutely hydrophobic. Apart from this, 3-dimensional pores are formed between individual fibres in the bunches of fibres.…”

This paper reports the state of art in a variety of pressure and the detailed study of various matrix based pressure sensors. The performances of the bridges, buildings, etc. are threatened by earthquakes, material degradations, and other environmental effects. Structural health monitoring (SHM) is crucial to protect the people and also for assets planning. This study is a contribution in developing the knowledge about self-sensing smart materials and structures for the construction industry. It deals with the study of self-sensing as well as mechanical and electrical properties of different matrices based on pressure sensors. The relationships among the compression, tensile strain, and crack length with electrical resistance change are also reviewed.
