Abstract Polypropylene, steel, and carbon fibers are used to increase the ductility toughness of concrete materials. In recent years, studies on use natural have increasingly continued. Among fibers, hemp fiber has highest tensile strength value. The aim this study was discuss present results experimental cement-based shives mortars. Another is in construction field by using more economical fib...

This paper presents a study of the possibilities of evaluating thermal parameters of single and multilayer structures using dynamic thermography. It also discusses potential uses of lock-in thermography. It presents a simulation of a periodic excitation of a multilayer composite material. In practice, the described methods can be employed in various applications, for example, in multilayer nonw...

Over time, many researchers have conducted studies to investigate the construction sector by assessing those related energy, environmental and economic problems find ways improve global sustainability. The on use of natural fibers: wheat, date palm hemp as an insulating material in concrete panel yields been through ten previous research studies. In market, there are various types thermal insul...

Clarke, R.C. 1995. Hemp (Cannabis sativa L.) Cultivation in the Tai'an District of Shandong Province, Peoples Republic of China. Journal of the International Hemp Association 2(2): 57, 60-65. This paper summarizes the history of hemp (Cannabis sativa L.) cultivation and traditional use in the Tai'an District of Shandong Province in the People's Republic of China, and investigates the cultivatio...

The aim of this work was to explore how various surface treatments would change the dispersion component of surface energy and acidbase character of hemp nanofibers, using inverse gas chromatography (IGC), and to investigate the effect of the incorporation of these modified nanofibers into a biopolymer matrix on the properties of their nanocomposites. Bio-nanocomposite materials were prepared f...

Natural fibers, including mineral and plant fibers, are increasingly used for polymer composite materials due to their low environmental impact. In this paper, thermographic non-destructive inspection techniques were used to evaluate and characterize basalt, jute/hemp and bagasse fibers composite panels. Different defects were analyzed in terms of impact damage, delaminations and resin abnormal...

During the growth of biomass, there are two carbon storage paths for plant-derived fibers. One path is to assimilate dioxide (CO2) from atmosphere through photosynthesis and temporarily store it in textile plants. Besides, can be captured stored soil. The capacity products made fibers such as cotton, flax, hemp, kenaf bamboo fiber, etc., a non-negligible part greenhouse gas (GHG) accounting rep...
