    Defects of communication pipes from plastic in modern civil engineering
    (TJPRC Pvt. Ltd., 2018) Lyashenko, V.; Ahmad, M. Ayaz; Sotnik, S.; Deineko, Z.; Khan, Alveera
    Plastic is an important material that is used in civil engineering. Communication pipes - one of the directions of use of plastic. The external environment affects the quality of the use of plastic pipes. Therefore it is important to know the defects of plastic products. It is also necessary to make assessment of the quality of the use of plastic pipes. It depends on many factors. Therefore the task of detection and preventing of the communication pipes defects - the complex task. We did a survey of the major defects of the communication pipe. We have examined the factors that influence the formation of defects in the communication pipe. A classification of variable factors that affect the quality of communication pipes is proposed. A generalized algorithm for evaluating the quality of communication pipes has also been developed.

    Some Effect of Chemical Treatment by Ferric Nitrate Salts on the Structure and Morphology of Coir Fibre Composites
    (Scientific Research Publishing, 2015) Khan, Alveera; Joshi, Shirish; Ahmad, M. Ayaz; Lyashenko, V.
    The present study shows some important effects of chemical treatment on the structure and morphology of coir fibre. The objective of the present study is to optimise overall properties of coir fibre so as to use coir fibre as a reinforcing agent in thermoplastic and thermosetting polymers. In the present study, coir fibre is treated with ferric nitrate salt. A thermal treatment has been done at temperature of 1000˚C by using annealing method. X-ray diffraction of the treated coir fibre reveals the crystalline nature of the fibre. Change in morphology has been found in coir fibre when subjected to scanning electron microscopy. Finally, the Fourier transform and infrared spectrographs show the presence of traces of iron oxide:fibre in the prepared composite.
