“…Nano-silica, which is also known as condensed silica fume, is one of the most important materials used to replace 7 -15 % of the total cement material in the cement mortars [7]. Nano-silica was reported to improve the packing characteristics of the cement mortar leading to improved mechanical properties [8][9][10][11].…”

Manufacturing of building materials with unique properties is one of the most important key-parameters in the development of construction engineering and building materials. The development in the nanomaterials and nanotechnology can be utilized in this field. In this paper, production of eco-friendly, low water absorption and self-cleaning cement mortar reinforced with carbon nanotubes and nano-silica with different weight percentages (0.5%, 1.5%, and 2%) is performed. Results showed prominent improvement of hardness, compression strength and a decrease of water absorption and bending resistance in the reinforced cement mortars. The results show the possibility to control the mechanical properties of the cement mortars with minimal reinforcing agents provides the possibility to design these building materials for versatile applications.

“…However, in the long run problems arise especially in the quality of these types of pavements after several years of services like rutting, cracking, bleeding and permanent deformations [1]. Many researches have been carried out over the past decades to improve the quality of pavement by modifying the asphalt mixture [3,4,5]. This concept of modification is not common nowadays especially when the industry is foreseeing challenges with sustainable raw material and earth resources.…”

Improvement in transportation system is never been as easy as just providing links for better connection and network but more to do with the pavement quality of the road itself. Modification with agriculture waste is just another approach to enhance the performance of asphaltic concrete. In this study, a non-traditional bitumen modifier from a coconut shell which is the charcoal coconut shell ash (CCSA) was used. Addition of CCSA in bitumen with 0%, 2%, 4%, 6%, and 8% by weight of bitumen were investigated along with the laboratory stimulation of aging was applied in this study. Properties of modified asphalt mixture were determined using resilient modulus, dynamic creep and Marshall Stability test.. Results of samples with CCSA which underwent aging show some improvement in terms of the stability and permanent deformation characteristics. Resilient modulus, dynamic creep and Marshall Stability tests recorded the highestrates when compared to controlled sample. Hence, for more durable asphalt concrete and high serviceability it is recommended to use 2% to 4% of CCSA.
