In industrialized countries, most of the reinforced concrete (RC) structures and infrastructures have more than 40 years, since they were built around 1960 − 1980, designed for a service life 50 years. Consequently, in next number infrastructuresthat will need to be repaired steeply increase. Several techniques, characterized by different durability, environmental impact economic impact, are av...

during the past two decades the use of lignocellouse fibers in reinforcing composites has attracted much research activities. in the present work, date palm fiber was used for production of composites compatible withliving environment. the fibers were pre-treated chemically to remove impurities. in order to verify and compare the effectiveness of the pretreatment methods, lignin, ash, moisture ...

Abstract The main purpose of the present work is to demonstrate mechanical performance a wet-compression-molding (WCM) composite product through conventional compressive-strength-after-impact (CSAI) analysis. Biaxial non-crimp fabric (NCF) utilized manufacture laminated panels. Specimens are cut from panels and tested characterize fundamental properties NCF composite. volume fractions fibers vo...

Objective Titanium dioxide (TiO2) is a white pigment which is used in paints, plastics, etc. It is reported to induce ‎oxidative stress and DNA damage. The N-acetylcysteine (NAC) was used to fight oxidative stress-induced ‎damage in various tissues. The aim of this study was to evaluate the toxic effects of TiO2 nanoparticles by oral ‎administration and the protective role of NAC on testes of a...
