“…In the neat PVA spectrum, the peaks belonging to the typical O–H (3280 cm −1 ) and C–H (2939 cm −1 ) bands were evident. [ 22 ] Comparing the curves of PVA and TPVA, the absorption peak of Ti–O band at 662 cm −1 appeared after modification of PVA. [ 23 ] Furthermore, absorption peaks of other organic functional groups had no significant changes because of little HY‐109.…”

Bone defects in the load‐bearing area require bone reconstruction using strong biomaterial with mechanical properties like cortical bone. Herein, the high‐strength/high‐modulus polyvinyl alcohol fiber (PVA) was first designed to incorporate into poly(amino acid) (PAA)/hydroxyapatite (HA) to obtain a new poly(amino acid)/hydroxyapatite/polyvinyl alcohol fiber (PAA/HA/PVA) composite via a melt extrusion process. To improve the interfacial adhesive performance, the titanate coupling agent HY‐109 [isopropyl tris(dodecylbenzenesulfonyl) titanate] was used for simultaneously graft modification of the PVA fiber and HA (TPVA, THA). The effect of their components on the mechanical properties and degradation ability were investigated by electromechanical universal testing machine and in vitro phosphate buffer solution soaking. The results indicated that the PAA/30THA/20TPVA composite had the most ideal mechanical and degradation properties, which far exceed those of PAA and PAA/THA composite. In addition, in vitro simulated body fluid immersion and cell culture experiment showed the PAA/THA/TPVA composites boosted in vitro bioactivity and exhibited excellent cytocompatibility and osteogenic activity in cell attachment, proliferation, alkaline phosphatase activity, matrix mineralization, and osteogenesis‐related gene expression. These reports demonstrated that the developed PAA/THA/TPVA composite displayed comprehensive performance optimizations, which showed its potential as a novel biomaterial to be applied as load‐bearing implant in the field of orthopedics.

“…In the laboratory, variations of mix proportions have been prepared to use a 5 cft cementitious material machine, when concrete mixture was laid on a concrete surface after mixing [45,46]. To determine the workability of freshly mixed concrete, a slump test is immediately conducted (Figure 5).…”

<p>In concrete industry, the use of concrete solid wastes is becoming further common since it can minimize associated costs and environmental implications. The current research looks at how concrete performs when polypropylene (PP) plastic, produced from pollution garbage items, is used as a partially replacing for coarse aggregate (CA). The proportion of total PP (PPA) (0, 5, 10, 15, and 20%) as well as the water-cement ratio 0.45 of recycled household waste water, are the most important variables. Flow ability, hard porosity, maximum compressive strengths are all factors to consider, and economic feasibility are all discussed. The slump value grew when the proportion of PPA was raised, according to the findings. Compressive and cracking tensile strengths were increased in concrete containing 15% PPA. As a result, suggested to utilize more than 10% PPA in structural concrete, with either crushed stone or PP aggregate. The results showed that 15% is the best alternative to coarse gravel during terms of strength and durability, and hence PPA can be utilized as a partial replacement for coarse aggregate in concrete. To conduct studies to enhance the impact resistance of concrete by utilizing recycled water. Reducing the consumption of nonrenewable resources reducing greenhouse gas emissions and improving the strength and load capacity of industrial materials used in building research. Finally, employing non-biodegradable waste plastic resources to make green concrete will offer up new possibilities.</p>

The Effects of Nano-Based Bio-Carbonates in Superhydrophobic Concrete—A Review

et al. 2023

Concrete must be a hydrophilic compound that is easily fabricated by nature. At the nanoscale, mechanical and chemical reactions alter the quality of cement-based substances. Continuous sprinkling of nano-silica solution synthesised with minimal surface solvents has been used to create a superhydrophobic (SH) concrete surface while similarly modifying the surface’s chemical composition and dynamical intrinsic structure. In this study, we examine the impacts of admixtures in SH concrete including nano-based bio-carbonate. The fundamental characteristics and dispersal techniques of nanoparticles often employed in cement-based compounds are reviewed initially in this paper. Investigations of the large contact angle, small slide angle, and carbonated thickness have been employed to analyze the impacts of admixtures. Additionally, the industry and uses of nanoparticles for concrete substances are addressed, and the expense is inventively represented by a survey questionnaire. Finally, this article identifies the obstacles that now occur in the field of research and offers appropriate future viewpoints.
