Application of automation in construction work has now become need the hour. Automation can be done by implementing a technique known as additive manufacturing technique. Use sector potential to bring fourth industrial revolution using 3D concrete printers. This paper is based ona parametric experimental study evaluate effect Polypropylene (PP) fibers on mechanical properties printable concrete...

The behavior of stone groundwood / polypropylene injection-molded composites was evaluated with and without coupling agent. Stone groundwood (SGW) is a fibrous material commonly prepared in a high yield process and mainly used for papermaking applications. In this work, the use of SGW fibers was explored as a reinforcing element of polypropylene (PP) composites. The surface charge density of th...

This research explains the melt spinning of bicomponent fibers, consisting of a conductive polypropylene (PP) core and a piezoelectric sheath (polyvinylidene fluoride). Previously analyzed piezoelectric capabilities of polyvinylidene fluoride (PVDF) are to be exploited in sensor filaments. The PP compound contains a 10 wt % carbon nanotubes (CNTs) and 2 wt % sodium stearate (NaSt). The sodium s...

The aim of this work was to study the formation process of dielectrophoretic (DEP) carbon nanotube fibers (CNT-fibers) and characterize the fiber properties relevant to their technological applications. The fiber diameter was shown to increase when applied voltage was increased (up to 350 V(pp)) and when retraction speed was decreased (down from 400 µm s(-1)) in accordance with theoretical expe...

The effect of fiber type and hybridization on the repeated impact strength was investigated experimentally using six high-performance concrete mixtures reinforced with a 2.5% volume fraction. types considered in this study included short steel fibers (SF) 6 mm length, long SF 15 polypropylene (PP) fibers. test conducted specially made automatic testing machine following setup recommendations AC...

Synaptic structures of neuronal contacts with pituicytes in the posterior pituitary (PP) were investigated in detail after wheat germ agglutinin conjugated horseradish peroxidase (WGA-HRP) injection into the rat hypothalamus including the paraventricular, dorsomedial and arcuate nuclei. The injection resulted in heavy labeling of hypothalamic fibers in the PP. In the neuropil of the PP, there w...

In the present work, microfibrillar composites (MFCs) consisting of polypropylene (PP) and poly(ethylene terephthalate) (PET) were successfully produced by melt extrusion cold stretching. The resulting filaments then printed using fused filament fabrication. morphological results demonstrate that highly oriented PET fibrils after stretching are still well preserved in components. Since printing...

Roller compacted concrete (RCC) is a relatively new alternative construction material that can be used in road and dam constructions by allowing rapid use after production the of conventional building materials production. RCC, which produced with low water/cement ratio, one rigid pavement types shows similarity to flexible pavements technique. Different fibers such as steel polypropylene (PP) ...

Bio-based wood materials are preferable for composites because of their sustainability, but adequately dispersing fibers in polymers can be difficult and costly. Our approach was to pretreat the with a green solvent system, allowing composite extruded single step, simplifying process, reducing overall cost. This study investigates fibrillation untreated sawdust (W) deep eutectic solvent-treated...
