Nanoclays are new generation of processed clays of interest in a wide range of high performance composites. In other words, nanoclay is defined as a clay that can be modified to make the clay complexes compatible with organic monomers and polymers. Here, it can be said that the polymeric nanocomposites are among the most exciting and promising classes of materials discovered recently. A number ...

In this study, age hardenable material Aluminum alloy Al-7075-T6 (aged) was investigated for weldability. Al-7075-T6 plates were subjected to Al-7075-0 heat treatment and were joined with different welding parameters by means of friction stir welding method. After Joining, the parts which were subjected to tensile and bending tests were examined. As a result of the studies, it was observed that...

Glycyrrhiza glabra extract is gaining increasing acceptance as a folk remedy for treatment of wound. We studied the effect of its extract on wound tensile strength in albino rats. 20 male albino rats had a linear 3 cm incision made over skin of back. The animals were randomly divided into two experimental groups, as control and treatment. Animals of control group received topical cold cream onc...

the marble slurry wastes (msw) produced by marble industry is left unattended in theenvironment which causes serious environmental problems. in order to evaluate its potential usage in normal1:2:4 concrete, this study was designed, where the partial replacement of cement with msw was examined.replacement of cement with msw from 0 to 100%, and also its usage as an additive material 10% and 20% b...

Leaf-litter assays have advanced understanding of decomposition processes in both terrestrial and aquatic ecosystems. Some shortcomings inherent in the technique may be overcome through use of a cotton-strip assay. Key assumptions for using cotton strips as proxies for natural leaves are: 1) decomposition rates of the 2 materials are related, and 2) the materials decay in a similar way when exp...

Commercial adhesives present a high bond strength and water resistance, but they are considered non-healthier products. Chitosan can be as an interesting biosourced biodegradable alternative, despite its low resistance. Here, wood bonding implementation tensile shear in dry wet conditions were investigated depending on structural characteristics. Firstly, the spread rate, open assembly time, dr...

In this research, the efficiency of Recycled Glass Powder (RGP) is evaluated for improvement of polymer-modified bitumen and asphalt mixture performance. An extensive laboratory programm was undertaken for polymer-modified bitumen including Crumb Rubber (CR), Styrene Butadiene Styrene (SBS) and Styrene Butadiene Rubber (SBR). Rheological and mechanical proper...

Fiber-reinforced composite (FRP) materials have gained an increasing success, mostly for strengthening, retrofitting and repair of existing historic masonry structures and may cause a significant enhancement of the mechanical properties of the reinforced members. This article summarizes the results of previous experimental activities aimed at investigating the effectiveness of GFRP (Glass Fiber...

Objectives/Goals This project was designed to determine how varying the amount of a specific ingredient that constitute a bioplastic mixture can affect tensile strength. I hypothesized that if more glycerin is added to a mixture of cornstarch, water, vinegar, and glycerin, then a bioplastic with increased tensile strength and flexibility will be produced. Methods/Materials Mold, 40 bioplastics ...

Granite is a typical crystalline material, often used as a building material, but also a candidate host rock for the repository of high-level radioactive waste. The petrographic texture-including mineral constituents, grain shape, size, and distribution-controls the fracture initiation, propagation, and coalescence within granitic rocks. In this paper, experimental laboratory tests and numerica...
