Mr Ali Yousefi
Ali received his Bachelor’s Degree in the field of Civil Engineering in 2005. He has worked in the construction industry as a construction engineer and site supervisor. His interest in engineering scientific research led him to pursue his postgraduate studies in the field of structural health monitoring at the University of Science Malaysia. He has been involved in academic research since 2010. Currently, he is doing his PhD at the School of Architecture and Built Environment. His PhD project focuses on incorporating phase change materials (PCMs) with concrete products for integrating into building components to reduce energy consumption in buildings.
He is enthusiastic about sustainable development in the construction industry, developing building materials and improving their properties. His primary research expertise lies in utilising recycled materials such as recycled glass and recycled concrete aggregates in concrete products.

Multi-walled carbon nanotubes (MWCNTs) with extraordinary properties have shown a promising role toward enhancing the flexural performance of cement composites. This paper investigates the effect of concentrations of MWCNTs on major flexural properties of cement mortar composites, including flexural strength, strain capacity, modulus of toughness, and modulus of elasticity. For this purpose, cement mortar reinforced with various concentrations of MWCNTs (0.02, 0.05, and 0.1 wt.% by weight of cement). Dispersion of MWCNTs was carried out using ultrasonic energy and concrete superplasticizer as surfactant agent. Prismatic beams of sizes 100 mm×100 mm×500 mm were fabricated and four-point bending tests were performed on the beam specimens at the age of 28 days. The results from bending tests indicated substantial improvements in the flexural strength, strain capacity and modulus of toughness of MWCNT-cement mortar, while the modules of elasticity remained constant. It was observed that specimens reinforced with 0.05 wt.% of MWCNTs exhibited higher flexural properties enhancement. Besides, it was noticed that with the increase of MWCNTs content, the flexural properties of MWCNT-cement mortar increased. The microstructure observation of MWCNT-cement mortar demonstrated well dispersion of nanotubes with concentration of 0.05 wt.% but large agglomerates and bundles of MWCNTs depicted within the sample with higher loading of MWCNTs (0.1 wt.%). It was concluded that the properties enhancement of MWCNT-cement composites highly depends on the concentration of MWCNTs and the level of dispersion of nanotubes in the cement matrix.
